Researchers have come to this conclusion based on the "genetic footprints" of the long-lost species Chelonoidis elephantopus in the DNA of their hybrid sons and daughters.

However, despite the claims of those who fear 2012, there's no evidence that such a supereruption is imminent.

Researchers only needed 15 days to map its formation in high resolution. The volcanic cone has reached a height of 100 m and the lava tongue flows down its side, even though its activity has slowed down in the past few days.

A new model points to a combination of temperature influence and the geometrical configuration of the magma chamber as a potential cause for these super-eruptions.

Rock of the oceanic crust, which sinks deep into the earth due to the movement of tectonic plates, reemerges through volcanic eruptions after around 500 million years.

The event is intriguing because the scientists had forecast the eruption starting five years ago -- the first successful forecast of an undersea volcano.

Using ship-borne sea-floor mapping technology during research cruises onboard the RRS James Clark Ross, the scientists found 12 volcanoes beneath the sea surface -- some up to 3 km high. They found 5 km diameter craters left by collapsing volcanoes and seven active volcanoes visible above the sea as a chain of islands.

NASA has collected them in an image gallery that shows the progression of the plume around the southern hemisphere.

One year after the Eyjafjallajökull volcano in Iceland brought European air traffic to a standstill its ash plume revealed a surprising scientific finding: Researchers found that the ash plume contained not only the common volcanic gas sulfur dioxide, but also free chlorine radicals. Chlorine radicals are extremely reactive and even small amounts can have a profound impact on local atmospheric chemistry. The findings give solid evidence of volcanic plume chlorine radical chemistry and allowed calculations of chlorine radical concentrations.

Now nanoscientists have developed a way to provide the necessary information within hours.

The image suggests the plume is even bigger than it appears in earlier images made with earthquake waves.

Mon, 04 Apr 2011 13:06:06 EDT http://www.sciencedaily.com/releases/2011/04/110404130615.htm http://www.sciencedaily.com/releases/2011/03/110328151734.htm Most deep-sea volcanoes produce effusive lava flows rather than explosive eruptions, both because the levels of magmatic gas tend to be low, and because the volcanoes are under a lot of pressure from the surrounding water. But by using an ion microprobe, researchers have now proved that explosive eruptions can also occur. Mon, 28 Mar 2011 15:17:17 EDT http://www.sciencedaily.com/releases/2011/03/110328151734.htm http://www.sciencedaily.com/releases/2011/03/110306234145.htm A fissure that opened on Kilauea's east rift zone after the March 5 collapse of the Pu'u 'O'o crater floor continues to erupt lava. Activity along the fissure was sporadic overnight and throughout the following day, with periods of quiet punctuated by episodes of lava spattering up to 25 meters (80 feet) high.

A theoretical model was tested on two major eruptions and completely overturned this hypothesis: the reawakening of a chamber could take place in just a few months. This research should lead to a reassessment of the dangerousness of some dormant volcanoes.

Wed, 23 Feb 2011 13:38:38 EST http://www.sciencedaily.com/releases/2011/02/110223133852.htm http://www.sciencedaily.com/releases/2011/02/110216123545.htm Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano, Iceland, encountered a problem they were unprepared for: magma which flowed into the well at 2.1 kilometers depth, forcing the researchers to terminate the drilling. The research team believes it should be possible to find reasonably shallow bodies of magma elsewhere in Iceland and the world, which would make for attractive sources of high-grade energy.

Analysis of erupted rock from Agrigan volcano in the western Pacific near Guam found it to be highly oxidized as a result of its exposure to oxygen when it formed in the Earth's mantle.

The finding could help scientists predict when Hawaiian volcanoes are going to erupt. It also suggests that Hawaii holds great potential for thermal energy.

But, in March 2008, an additional eruption vent opened at the volcano's summit, resulting in triple the amount of sulfur dioxide gas emissions drifting to the local community of Ka'u, raising health concerns over the risks associated with exposure to "vog," volcanic air pollution.

Most of the molten rock that comes out of these volcanoes is rich in water, but the team has shown that the volcanoes are aligned above narrow regions in the mantle where water-free melting can take place.

It will help scientists better understand the nature of Mount Hood's past and future eruptions, as well as other volcanoes that erupt by similar mechanisms. This includes a large number of the world's active volcanoes.

For several decades, scientists have pretty much used one theory to explain what is causing huge amounts of gas to erupt so frequently: swimming-pool-sized bubbles that travel through a few hundred meters of molten magma before popping at the surface. But they may be wrong, according to new research.

Bringing almost all transatlantic air travel to a halt for the first time in modern history, this volcano reminded humanity of the powers these forces of nature contain -- and of our relative inability to understand them. Researchers have studied this event and other massive volcanic eruptions and their atmospheric consequences in the past in North America.

They found mobility patterns in places far from Europe -- including the United States, India and southeast Asia -- were significantly affected by the European disruption, to the surprise of the team. At the top of the list of most affected airports still operating were Singapore, Hong Kong and Beijing.

In the latest Envisat image acquired April 22 at 13:36 CEST, less ash is visible.

New research provides more details about the actual height and development of the ash cloud as well as qualitative measurements of the volcanic ash concentrations in the cloud.

Over the last three days these satellites have provided visible and infrared imagery of the ash plume from the Eyjafjallajokull volcano in Iceland.
