Strong earthquakes powerful volcanic eruption in eritrea

A volcano erupted in the Southern Red Sea Region of Eritrea on early Monday morning, experts said, sending an ash cloud kilometers (miles) up into the air. It is the first eruption at the volcano since 1861. The chief forecaster at the VAAC in Toulouse said the eruption at the Dubbi volcano began at around midnight local time (2100 GMT Sunday), sending a large plume up to 13 kilometers (8 miles) high. Few details about the eruption in the remote region were immediately available.

The eruption was preceded by a series of more than a dozen light to moderate earthquakes at the volcanic complex, according to the United States Geological Survey (USGS). It said the two strongest earthquakes had both a magnitude of 5.7 on the Richter scale. A seismologist at the USGS earlier said he did not know if the earthquakes were related to the volcano since both originate from the same continental rift zone. “

This thing also tends to generate volcanic activity, given the fact that since you are opening the Earth’s crust, a lot of the magma that is underneath the Earth’s crust does actually have access to the surface,” the seismologist said earlier. “That process itself, the volcanism and the earthquakes, are related to the same rift zone.”

The Dubbi volcano, which has a peak elevation of 1,625 meters (5,331 feet), is the country’s only historically active volcano. It last erupted in 1861, destroying local villages and killing more than 100 people.

The moderate earthquake was followed by seven light earthquakes between magnitudes 4.5 and 4.8 on the Richter scale during the next 2.5 hours. Those were then followed by three earthquakes with magnitudes of 4.7, 4.8, and 5.0.

Soon after, at 11.32 p.m. local time (2032 GMT), a moderate 5.7-magnitude earthquake struck about 123 kilometers (76 miles) west-northwest of Assab at a depth of 10.1 kilometers (6.3 miles). It was quickly followed by another 5.7-magnitude earthquake, as well as a 4.5-magnitude earthquake. There were no immediate reports from the region, but the USGS said there was a possibility of damage and casualties as a result of the earthquakes.

It estimated that some 18,000 people may have felt moderate to strong shaking as a result of the 5.7-magnitude earthquakes, while 3.6 million others were estimated to have perceived light shaking. Earthquakes in Africa are rare, especially moderate earthquakes, but similar events have happened before in the region. On July 20, 1884, a strong 6.2-magnitude earthquake struck offshore Massawa, Eritrea. Scores of homes in the region were destroyed but there were no confirmed reports of fatalities.

Next volcano eruption

Recent increase is volcanic activity worldwide starting with Iceland's Eyjafjallajökull and volcanoes in Guatemala and Ecuador, made doom seekers think "what is the next volcano eruption"? Many people think Icelandic Katla is going to blow next with the power of three times stronger than Eyja. 

This certainly stands on solid basis because the history records show that Katla eruptions somehow follow its neighbor - Eyjafjallajökull.  But what is going on at Hawaii right now does not smell good - it smells like sulfur to most of the people I spoke with. To the point - small quakes are happening around Mauna Loa volcano on daily basis and the epicenters of the quakes are progressively climbing towards Earth's

The eruption arab volcano

Much has taken place since the start of the year. There is no doubt that we are witnessing a ‘steady’ large volcanic eruption, but this is no normal volcano! This volcano has an unsteady history. Over the past century it’s lava has been filled with emotion, scars, hurt, and brutality. We have seen that on the odd occasion the volcano has released some of its black toxic fumes, to make way for more unrest that has followed.

I believe the time has come, these bubbles are getting bigger and bigger, and each bubble has its own tale to tell. If the heat alone is unable to make its surroundings wary of the danger it faces, then the anger and frustration that comes with it causes a deadly mix that no one will be able to stop. The guardians of this volcano knew of the dangers that they faced if the volcano were to erupt. Instead of cooling it down and keeping it steady, they have been managed to ignite the volcano with medieval tactics, and the highly flammable toll is now there for all to see. 

We have witnessed recently the volcano releasing flying pebbles of stone which are coated with extremely hot lava, these latest developments have caused casualties within those who guard the regimes, and has no doubt brought them fear.I think our people in the Middle East have had enough, our beloved friends in Tunisia have taken the lead and shown us all that these ignorant thugs who think they can play God with innocent lives can be defeated if all shall rise as one.

Our Egyptian friends have started to wake up from an inception which has lasted more then two decades, the road is still yet long for them before they can finally taste the sweetness that their neighbours in Tunisia have experienced, but God willing justice will prevail, the innocent cries and prayers will be answered to. I see that the line is getter bigger and each state is wanting to chew on the success which the Tunisians have had, the flags of Algeria and Yemen are the two that can be seen up close. All hail to the people of the Middle East who have finally come to realise that the key to change … is to let go of fear … and boy are they starting to let go of fearing those who have no fear of God!

Kilauea Volcano Erupts Again

The Kilauea volcano, a source of eruptions since the early 1980’s, erupted again yesterday, raising lava 65 feet high into the air, after the Puu Oo Crater collapsed. This eruption continues to fuel the spectacular lava show that is happening on Hawaii’s Big Island.

Although the volcano appeared peaceful lately, allowing for visits and scientific probing, Don Swanson, a scientist with the Hawaiian Volcano Observatory believed that the great fire mountain was giving everyone the wrong impression, and yesterday’s eruption proved him right. According to a message recorded by the Hawaii Volcanoes National Park, the Kilauea volcano kept erupting from inside the mountain since Monday. Thus the park seized all activity along the coastal trails, called the east rift zone, the Kulanaokuaiki and the Chain of Craters Road.

The lava show can be however watched and recorded by visitors. Two recommended places for this activities are the patio of the Jaggar Museum and the Kalapana View site. The First one is open for public between 8.30 a.m. and 5 p.m. daily and the second between 2 and 10 p.m. daily.

A warning concerning the fog concentration in the air has been issued. Thus, people who feel some breathing difficulties should remain inside, although most of the areas are clear and the air quality is adequate.

Krakatoa Island

On August 27, 1883, the island of Krakatoa literally exploded due to four volcanic eruptions. The explosions were so intense that they were heard 3,000 miles away, global. the shockwave circled the globe seven times! the island has grown up again and is now known as Anak Krakatau (Son of Krakatau). It remains volcanically active and has been steadily growing larger. Can it be much longerbefore another Krakatoa?

Volcanoes

This week we move from talking about anger in general to examining anger on a personal level.  We are going to see what we look like when we explode and what damage it creates.  We will discuss the three masks of anger and discover which mask we tend to wear.  

A volcano, in essence, is a natural thing that explodes under pressure.  And that’s exactly what can happen to us when motherhood gets to be just too much for us.  In an instant, we can change from the peaceful, nourishing women we want to be into Mount Momma – spitting fire and brimstone at all who cross our path.

There are four common types of volcanic eruptions in angry moms:

The Strombolian: 

Short eruptions at fairly predictable intervals that seem to blow over with little residual damage. Verbal cinders of sarcasm (Yeah right, Einstein!) smolder in our children’s hearts and cinders of regret (longing to take back words and thoughts) sear our conscience. You regularly don’t laugh, relax or enjoy your children. Small eruption after small eruption results in cumulative damage. Small eruptions and cinder damage can eventually bring about as much damage as any other kind of eruption.

The Hawaiian: 

Lakes and rivers of constantly boiling lava seething away in its crater, doing little damage. Sooner or later it boils up in the crater and overflows the sides, or it breaks through cracks and fissures and starts flowing out. You have chronic, simmering anger and aren’t really the explosive type. You don’t think of yourself as an angry person. However, there is a lot of turmoil bubbling inside of you all the time. 

But if you simmer and seethe long enough, even though you may avoid a violent explosion, sooner or later the anger and negativity is going to break out and the resulting damage may be all the greater because your anger doesn’t seem all that dangerous on the surface. The lava flow is mostly verbal – caustic criticism, negative assessments, unfavorable comparisons, sarcastic barbs, teasing that carries an edge or pessimistic pronouncements about life in general. These are all forms of spoken terrorism that scorch and burn our children. The most marked characteristics of The Hawaiian is that they often mask themselves as innocent remarks and actions and they can go on for a long time.

The Vulcanian: 

 Seethes with pent-up molton rock, then expels blobs of viscous magma in a huge explosion. The explosion is loud, scary and dangerous, violently ejecting solid fragments that are hot and deadly, and poisonous gases. You produce shrapnel – verbal, physical and emotional – that can shred the spirits of your children and the safety of your home. 

You may throw things or use poisonous words and actions (insults, accusations, slaps and shakes). The wrath is unpredictable and doesn’t pass quickly, but can be sustained for days on end, usually aimed at a particular child. The distinguishing characteristics are the “don’t want to stop” level of emotion and becoming engaged in willful, increasingly harder-to-stop behavior.

The Plinian: 

 The most violent and unmistakable of all explosions. Everything about it is big and bad. The distinguishing characteristic is the sheer volume of material ejected by the eruption and the sheer power of the explosion that throws it out. It wreaks terrible havoc upon yourself, your children and your relationships. 

This type of extreme, explosive anger, though it might erupt infrequently, can easily destroy everything you hold dear. This is an angry explosion that causes your children to hide from you or leave the house, leaves you hoarse from screaming, results in physical abuse or verbal lashings that later wither your heart and makes you wonder what kind of monster you’ve become.

Giant volcanic eruption

Scientists have uncovered evidence of a previously unknown giant volcanic eruption which they claim led to global mass extinction 260 million years ago.

The new study suggests the eruption in the Emeishan province of south-west China unleashed around half a million cubic kilometres of lava, covering an area five times the size of Wales, and wiping out marine life around the world.

The authors claim they have been able to pinpoint the exact timing of the devastating eruption and directly link it to mass extinction across the planet.

They claim it is due to the fact the ancient eruption occurred in shallow sea, and therefore its lava appears today as a distinctive layer of igneous rock sandwiched between layers of sedimentary rock containing easily datable fossilised marine life.

The layer of fossilised rock which appeared directly after the eruption contains evidence of mass extinction of different life forms, the authors write, which they suggest claim clearly links the onset of the eruptions with a "major environmental catastrophe".

It's believed the collision of the lava with the shallow sea would have caused a violent explosion during which vast amounts of sulphur dioxide were thrown up into the stratosphere.

Scientists believe the presence of the sulphur dioxide in the atmosphere would have led to the planet cooling and ultimately resulting in an outburst of acid rain.

"The abrupt extinction of marine life we can clearly see in the fossil record firmly links giant volcanic eruptions with global environmental catastrophe, a correlation that has often been controversial," Professor Wignall concludes.

Volcanic Eruptions

Volcanos are openings in the earth's crust through which molten lava, ash, and gases are ejected. They have caused some of the worst disasters in history, including wiping out entire cities and killing thousands of people. They impressed the Romans so much that their god of fire was represented by a volcano. 

In fact, that's where the word comes from. It comes from Vulcan, the Roman fire god. They believed that Vucan lived on an island of the Italian coast. The island was volcanic. They called the island Vulcano. Scientists have divided volcanic eruptions in to four basic groups based on the violence of the eruption and the type of material that erupts. The four groups are Hawaiian, Strombolian, Vulcanian, and Peleean. Hawaiian eruptions are named after the volcanoes in Hawaii and are the least violent type. They produce highly fluid lava that flows quietly from several vents. This gradually builds up a shield volcano.

 

Strombolian eruptions are named after Stromboli. These result from the constant release of gas from the magma. As the gas escapes, it produces tephra that piles up, turning into a cinder cone. Volcanic eruptions get their name from the Roman island Vulcano. Strombolian eruptions happen when sticky magma plugs the central vent. This makes the magmatic gas build up pressure until it blasts. 

The magma is turned into volcanic dust and bombs. The most violent kind of eruptions are the Peleean. Their name comes from the eruption of Mount Pelee in 1902 on Martinique, which killed almost 38,000 people. A Peleean eruption occurs when the magmatic gas build up tremendous pressure. 

This causes violent explosions with glowing clouds of hot ash and dust. Most of the volcano gets torn apart too. It is very hard to predict when a volcanic eruption will occur and most cannot be predicted. When volcanoes erupt, little to nothing can be done to save property, but many lives can be saved if the area if evacuated soon enoughtIt is a constant priority for scientists to figure out how to predict them, and they have already made a little progress. Scientists use several devices to figure out when a volcano will erupt. 

One such instrument is called a tilt-meter, they use it to measure the expansion of a volcano. Thermometers are often used to check the temperature in the surrounding area and gas detectors are used to measure the amount of gas. Though these instruments aren't perfect, they do help.

Volcanoes also have many benefits. Many volcanic materials have important industrial and chemical uses. Lava rocks can be used in roads, while pumice is used for grinding and polishing metals and other materials. Volcanic ash improves soil fertility and the underground steams volcanoes produce can be used as a source of energy. Besides these everyday uses, scientists can use volcanoes as "windows" to the inside of the earth. By studying them and the materials they erupt, scientists can gain a better understanding of the earth.

Effects from Eyjafjallajökull on European Vineyards

My knowledge of Iceland prior to last week’s volcanic eruption of Eyjafjallajökull was slim at best. I knew of shaggy, squat horses that ran wild over vast open swaths of land. Their traditional foods such as skyr, cured ram scrota, fermented shark and singed sheep heads have always held a perplexing fascination, while singers such as Bjork have paved an unforgettable international reputation. Essentially, it’s a culture I’ve eagerly wanted to wrap by brain around but have yet the opportunity to do so, until now. 

With the mass amount of media covering the looming cloud of volcanic ash from Iceland’s Eyjafjallajökull sitting maniacally over our heads, I’ve learned a considerable amount about Iceland. Yet, Ryan and I couldn’t help but wonder if there would be a direct effect to European vineyards, both now and in years to come.

Mount Pinatubo erupted in June of 1991, producing the second largest terrestrial eruption of the 20th century after the 1912 eruption of Novarupta. It sent approximately 10 billion metric tonnes of magma into the air, along with 20 million tons of SO₂, while Eyjafjallajökull is only sending approximately 3,000 tons of sulfur dioxide into the atmosphere. For a volcano to have a measurable effect on the climate, large amounts of sulfur dioxide must be emitted into the stratosphere, as exemplified by Pinatubo, which dropped temperatures by approximately 0.5 °C (0.9 °F)

If, however, the cloud lingers for months at a times, not only could we see a significant reduction in photosynthesis, but also a direct impact on the vintage itself. “I have never seen any direct studies on this issue. The closest parallel is the issue of smoke from forest fires which can cause depending on its severity, timing in the plant’s growth cycle, and length.” smoke taint in wine “The impacts would depend mainly on ash thickness, the type and growing condition of a crop, the presence of soluble fluoride on the ash, timing and intensity of subsequent rainfall. Most of the studies discuss large deposition effects (>100 mm of ash). But I could see where small quantities of both solid or liquid deposition could have a short term effect on plant growth.”

Volcano Eruptions

A volcano is an opening in the Earth’s crust that allows hot ash, lava, and gases to escape through the hole. Volcanoes are usually located in places where the tectonic plates are diverging or converging.

So, then what makes a volcano erupt ? Natural radioactive decay that occurs within the Earth causes pressure that affects the magma in a volcano. Although the concentration of these radioactive elements is not significant, it becomes more significant when you consider the volume of the Earth. Since the Earth is extremely large, a large amount of heat is produced from the radioactive decay. This heat causes more magma to melt. Since magma has a lower density, it then travels towards the surface.

Japan raises alert following volcanos biggest eruption 50 years

A one-mile cordon has been established around a volcano on Mount Kirishima after it erupted scattering rocks and ash across southern Japan and sending smoke billowing 5,000ft into the air.The Meteorological Agency raised the volcanic alert to level 3 as ash today continued to spew from Shinmoedake on Japan's southernmost main island of Kyushu, and residents have been banned from going within a mile of the volcano following its worst eruption in 50 years.

Force of nature: Lightning strikes as Shinmoedake erupts, scattering ash and rocks across a wide swathe of southern Japan

Ash and smoke continued to billow 5,000ft above Shinmoedake today as residents were banned from going within a mile of the volcano Agency volcanologist Sei Iijima said the eruption did not pose a threat to nearby cities, and a major eruption was not imminent. But he added: 'You can never say never with a volcano, although the lack of magma movement beneath the surface leads us to believe that this activity won't lead to a large-scale eruption,' he told ABC News.

The volcano, one of 20 inside Mount Kirishima, began erupting around 7.30am yesterday morning and by 3pm heavy smoke had risen to nearly 5,000ft, prompting the meteorological agency to raise the alert level. Volcanic activity is often reported at Kirishima, but this is the largest eruption recorded there since 1959. 

Volcanic activity is often reported in the Kirishima range, but Shinmoedake's is the largest eruption since 1959

 Under a cloud: A man takes a picture of erupting Shinmoedake from Takaharu, where an evacuation centre has been established Air space above the mountain remained open today but airlines cancelled a number of domestic flights because of the haze and the buildup of ash on train tracks forced Japan Rail to close several lines. Roads were also shut because of poor visibility. 

A small evacuation center was set up overnight in the town of Takaharu, seven miles east of Kirishima, and the town's general affairs manager Yuji Nakashima said: 'People told us their windows were rattling and they heard roaring sounds coming from the mountain.'

Volcano erupts in south Iceland

An Icelandic volcano, dormant for 200 years, has erupted, ripping a 1km-long fissure in a field of ice.

The volcano near Eyjafjallajoekull glacier began to erupt just after midnight, sending lava a hundred metres high.Icelandic airspace has been closed, flights diverted and roads closed. The eruption was about 120km (75 miles) east of the capital, Reykjavik. About 500 people were moved from the area, a civil protection officer said."We estimate that no-one is in danger in the area, but we have started an evacuation plan and between 500 and 600 people are being evacuated,"   

Sigurgeir Gudmundsson of the Icelandic civil protections department told the Agence France-Presse news agency. The area is sparsely populated, but the knock-on effects from the eruption have been considerable. A state of emergency is in force in southern Iceland and transport connections have been severely disrupted, including the main east-west road."Ash has already begun to fall in Fljotshlid and people in the surrounding area have reported seeing bright lights emanating from the glacier," RUV public radio said on its website. 

"

It was a bit scary, but still amazing to see," Katrin Moller Eiriksdottir, who lives in Fljotshlid, told the BBC News website. The ash had started falling and we couldn't leave the car." Three Icelandair flights, bound for Reykjavik from the United States, were ordered to return to Boston, RUV radio reported. 

Domestic flights were suspended indefinitely, but some international flights were scheduled to depart on Sunday. There had initially been fears that the volcano could cause flooding, as it causes ice to melt on the glacier above it, but that scenario appears to have been avoided. 

However, it could cause more activity nearby, scientists say. "This was a rather small and peaceful eruption but we are concerned that it could trigger an eruption at the nearby Katla volcano, a vicious volcano that could cause both local and global damage," said Pall Einarsson, a geophysicist at the University of Iceland's Institute of Earth Science, Associated Press news agency reported. 

As the eruption is taking place in an area that is relatively ice free, there is little chance of a destructive glacier burst like the one that washed away part of the east-west highway four years ago, after an eruption under the vast Vattnajoekull glacier. Iceland lies on the Mid-Atlantic Ridge, the highly volatile boundary between the Eurasian and North American continental plates, with quakes and eruptions. The last volcanic eruption in the Eyjafjallajoekull area occurred in 1821.

Sinabung volcano

The Indonesian volcano continues to experience explosions, which one last night (well, last night here in Ohio) that prompted an ash advisory for aircraft up to 6,100 m / 20,000 feet, although most reports I've seen pegged the ash column at closer to 2,000 m / ~6,500 feet.  This definitely makes it seem that the vent is partially blocked and these explosions are helping "clear the throat" of the volcano (NOTE: this does NOT mean I think something big is going to happen, rather just that it seems to be the reasonable explanation for the bifurcation of the plume).

My hunch is that even now, very little "new" juvenile magma has been erupted from Sinabung, but that is pure speculation until there are any analyses of the ash shard morphology or composition.  Evacuations have increased to over 21,000 people living near the volcano and some flights have been diverted due to the taller ash plume. The biggest threat right now is the ash fall from the explosions and as such, the government is providing face masks and moving people to sturdier shelter. The current death toll appears to be 8 (video), mostly from respiratory-related problems.

What comes next might be a guess for everyone at this point as the Surono, head of the Indonesian Center for Volcanology and Geological Disaster Mitigation admitted again "We don't know what set it off, how long it will continue or whether to expect pyroclastic flows or more powerful eruptions."

Eruptions readers were quick on the news about the new eruption at Sinabung in Indonesia. There isn't much known about the eruptive history of the volcano - checking out the Global Volcanism Program, the last activity at Sinabung might have been an explosive event in 1881 with persistent fumaroles up until 1912. However, most news sources are quoting 400 years as the last known eruption of the volcano, apparently information from the Indonesian government.

The eruption itself appears to be an ash-rich explosion with ash fall reported up to 30 km from the volcano although the ash column from the explosion was only 1.5 km (~5,000 feet) tall. The volcano had been showing signs of activity with smaller explosions and minor steam-and-ash plumes on Friday, but the explosion on Saturday was much larger than expected.

From the details I've read, [speculation] I wouldn't be surprised if there is no new magma (juvenile material) in this eruption, but rather just older material that was in the conduit. My hunch is that this explosion might be the start of more and the heat from the magma interacted with groundwater near the summit to cause the explosion - a very common precursor activity at a composite cone like Sinabung (think about the events leading to the eruption at Redoubt).

Thousands of people have needed to evacuate their homes around the volcano on Sumatra after this explosion - however, some have stayed behind to prevent the looting of their property. A 6-km exclusion zone has been set up around the volcano by the Center for Volcanology and Geological Disaster Mitigation as well.

Shield Volcano

Forces of nature are always unpredictable and cause massive destruction on the surface of the earth. Volcanoes are one of such forces that has swallowed the life from the face of the earth. They have a tendency to explosively erupt and spread up to a large area. 

 

As the pressure of gases, ash and hot magma increases, it explodes through the crust of the earth into the form of volcano. Depending on their frequency of eruptions they are classified into extinct, dormant and active. These volcanoes are made of different features which can help judge the behavior of each volcano. Let's take a look at how do shield volcanoes erupt and see their various types.

Fissure vents, shield volcanoes, lava domes, cryptodomes, cinder cones, stratovolcanoes, supervolcanoes, submarine volcanoes and mud volcanoes are some of the volcanic types, the names of which have been derived from their features. A shield volcano derives its name from its tendency to spread to a great extent. 

 

This volcano is made of only thin explosive fluid lava. At the time of its explosion, it shoots up at a height of 8 km and spreads in all directions. Due to the extremely fluid lava, the shield volcanic mountains are usually less steep. The exterior of the mountain has shallow slopes, which allows the hot fluid lava to spread in all directions. 

 

A shield volcano has a shallow bowl like structure called the summit caldera, through which it throws out the hot fluid. The hot lava that flows underneath the earth's crust, sometimes leaks out of the vents formed on the flanks. The Hawaiian islands, northern California and Oregon, are a home to many such shield volcanoes. 

 

Well-known Shield Volcanoes

▲ Mauna Loa

It is among the largest active shield volcanoes of the Hawaii, which is known for covering the area of 18,000 cubic miles with just 120 feet high peak. Mauna Loa frequently occurred form 24th March to 15 April 1984, but caused less damage to the life around it. However, its eruptions dated back in the 50s destroyed many villages. The lava that flows under, is extremely fluid and covers the shallow slopes of the mountain. The city of Hilo spreads over the dried lava of Mauna Loa. The existence of this shield volcano dates back some 700,000 years and since then been a part of the Hawaiian islands.

▲ Mauna Kea

Mauna Kea is also one of the volcanic mountain of the Hawaiian islands, which is located near the Mauna Loa volcanic mountain. Due to its less eruptions, it is considered as one of the dormant volcanoes. This volcano rises up to 30,000 ft above sea level. Mauna Kea is one of the oldest mountains that erupted 1,000,000 years ago and continued to be active for a few years.

▲ Kīlauea

Kilauea is one of the most active volcano in the Hawaiian Islands and is known for its 34 eruptions since 1952. As per the USGS, Kilauea is among the most dangerous volcanoes which has destroyed the entire settlement in the Kalapana area. Magma of this volcano flows 60 km deep under the earth's surface.

▲ Hualalai

Hualalai is a dormant shield volcano, located on the Hawaiian Islands. It stands 8,271 feet tall above the sea level and has come to exist some 300,000 years ago. This shield volcano is rated as the third most dangerous volcano. The last eruption of Hualalai was witnessed during the 1929 Swarm earthquake. The tremors of this earthquake were felt till Honolulu. The volcano has showed the signs of eruptions after every 200 to 300 years.

Shield volcanoes are considered to be the most destructive volcanoes of all. These volcanoes are present in different parts of the world and mainly occur during the diverging and converging movement of tectonic plates. The movement of tectonic plates not only results volcanoes but also give rise to earthquakes.

Eruption volcano

 

The advice would serve as a warning. Natives and residents of nearby areas could also tell when an eruption is eminent.Thus, volcanologists and seismologists would be able to advise people days or even months before the eruption of a volcano. That is because it would take some time before a volcano is able to accumulate enough lava that would trigger an eruption.Often, there are indicators that are monitored before an eruption of a volcano.

Preparing for Volcanic Eruptions - Fortunately, volcanic eruptions do not happen abruptly. Mudflow can also occur if there is rain over the crater of a volcano that is near eruption. Many people have lost properties and loved ones to raging and molten lava that erupting volcanoes produce.Often volcanic eruptions also accompany great and destructive earthquakes, making the disaster more catastrophic. Volcanic Eruptions - Through the years, people have seen the destructive potential of volcanoes. The other type id the destructive of the active volcanoes, which occasionally erupt.

Such volcanoes are like normal mountain and do not erupt. One is dormant and inactive. Types of Volcanoes - There are two kinds of volcanoes. All you need is to take precautionary measures when the volcano produces signs of eminent eruption. 

Be prepared for volcanic eruptions if you live nearby an active volcano. Volcanoes are truly one of nature's most destructive forces. Millions of people are living near and around them due to the beauty and fertility of the surround lands. Hawaii and other islands around the Pacific are also rich in volcanic supplies. The most destructive volcanoes are located in countries around the Pacific like Japan, Indonesia, the Philippines and New Zealand.

Most are located at special zones that are strategically located around the Pacific Ocean.Thus, the areas around the Pacific are collectively known as the Pacific Ring of Fire. Volcanoes are truly fascinating features of nature.

Volcano

 

As most people around the world probably know by now, there is a volcanic eruption going on in Iceland.

 

In the spring of 2008, 5 members of Mezzoforte spent a few days in a summer house in southern Iceland to write music for the album which is currently in the works. The nearness of Iceland’s best known and most active volcano Hekla (in plain view just a few kilometers away) sparked the idea for a song called Sleeping  Volcano. Written collectively by the band, the song was recorded later the same year in Vestmannaeyjar (another highly volcanic place in Iceland).

 During our stay in the summer house we were reminded of the awesome and unpredictable power of the Mid Atlantic Ridge when an earthquake measuring 6,1 on the Richter Scale shook the wooden house so violently that we could barely keep our balance to run outside.Little did we know that before long another neigbouring volcano under the glacier Eyjafjallajökull, less than 50 kilometers away, would erupt with the devastating consequences we see today. 

The members of Mezzoforte have not been directly affected by the eruption since prevaling winds are blowing the ash away from the capital Reykjavik. However our travel plans, like those of so many others, may well be disrupted if the eruption goes on for weeks, months or even years…

Volcano eruption causes choas in Europe

As I woke up for school one day last week and turned on the TV, news anchors continued to pour out new facts, the latest airline debt figure, and their own commentary on the eruption of the Eyjafjallajokull volcano in Iceland. When the volcano erupted on Wednesday, April 14, a large plume of ash was blown into the air cancelling thousands of flights and causing airlines to lose over $200 million a day while ash drifted over the northern European skies. 

It’s amazing to think how, in our high-tech world, a natural phenomenon such as a volcanic eruption, where no casualties or direct devastation occurred, can throw a part of the world into havoc. This eruption is just one of many recent windows that have been set up by Mother Nature for these scammers to benefit from.  Others include the earthquakes in Haiti, Chile, and China, and Thailand’s Tsunami.  But isn’t it the time that we, as neighbors, are supposed to cooperate and help as much as we can? Apparently not all of us think so.  In the midst of this turmoil, some people looked at it as a window of cruel opportunity.

As frustrated travelers waited hopelessly in airports, airlines scampered to reschedule flights, and millions of people watched the surreal events unfold on the news, pathetic con artists took full advantage to gain all the cash they could bargain from innocent people.   What happens in this situation is that these con artists find out a particular person’s location (a young man stuck in a London airport, for example) and retrieve the phone number or e-mail address of a vulnerable and innocent relative (mainly grandparents or aunts and uncles).  They then pose as the stuck family member asking the relative for a large amount of cash after explaining a false reason of why “they” need cash in a hurry.

In reality, they are probably miserable people too lazy to work for their own money.  And in an urgent situation, most family members would not hesitate to wire the money to help out their relative. I was stunned that people would dip this low for their own benefit. It’s a win situation for the scammer, but a lose-lose for the victims. Not only are they involved in or hurt by the disaster that just happened, they are out a few hundred or thousand dollars that they will most likely never see again.

So, props to the few human beings who never cease to amaze me with their constant greed and selfishness.  No matter what Mother Nature may have in store for us, a few of us always seem to feel the need to outdo her.  Keep up the good work! I think we’ll really grow from our experiences.

Feature Science Mission Impossible - Nyiragongo Crater

It is a matter of immense pleasure that a team of scientists and explorers stepped onto the shore of the lava lake boiling in the depths of Nyiragongo Crater, in the Great Lakes region of Africa. The molten matter of the volcano has been captured in camera from a minimum distance of 1 meter by the courageous photographer Olivier Grunewald.

Obviously the act has been performed with proper safety and scientific equipments. The camera was also prepared to protect 1300 degree Celsius heat. Nobody is encouraged here to repeat the same without any precaution to make a history, it was purely a professional arrangement under strict abidance of scientific and safety rules by highly experienced scientists, who had also undergone a four months training for the purpose. During the expedition the members of this team were in contact through radio uninterruptedly to chase the movement of the gas and lava.

The goal of this expedition was to enhance volcanologists’ knowledge so that mankind can be saved from disaster from the flame of volcano in the future by perfect prediction in this context.

Mount Nyiragongo is a stratovolcano (or sometimes termed as composite volcano) in the Virunga Mountains associated with the Great Rift Valley. Stratas means layers. So, the said volcano is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Normally the lava that flows from stratovolcanoes typically cools and hardens before spreading far due to high viscosity. However extensive felsic lava can flow up to 15 kilometers before solidified because of its thixotropic and shear thinning properties. Felsic is a geological term which refers to silicate minerals, magma, and rocks enriched in the lighter elements such as oxygen, sodium, potassium, silicon and aluminum.

Lava is a type of molten or melted rock expelled by a volcano during an eruption. This molten rock is formed in the interior of Earth. When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 degree Celsius to 1,200 degree Celsius equal to 1300 degree Fahrenheit to2200 degree Fahrenheit and up to 100,000 times as viscous as water.

Nyiragongo's lava lake has at times been the most voluminous known lava lake in recent history with an estimated 282 million cubic feet of lava. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about 20 km north of the town of Goma. Goma is a city in the eastern Democratic Republic of the Congo, on the northern shore of Lake Kivu, next to Rwanda. The main crater is about two km wide and usually contains a lava lake.

Volcanism at Nyiragongo is caused by the rifting of the Earth's crust where two parts of the African Plate are breaking apart. The African Plate is a tectonic plate which includes the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges.

The Nyiragongo mission is a great event which will be marked as a milestone in the history of geology. "News and Features” takes the pride to congratulate the whole team including Olivier Grunewald, Jacques Barthelemy, Dario Tedesco, Pierre-Yves Burgi, Franck Pothé and Marc Caillet for this historic success.
