The magma in this cove contains gases that are kept dissolved by the immense pressure under which the magma is contained.

The calderas lie over the,Over the past 18 million years or so, this hotspot has generated a succession of violent eruptions and less violent,The oldest identified caldera remnant straddles the border near.The volcanic eruptions, as well as the continuing geothermal activity, are a result of a great cove of magma located below the caldera's surface. If the pressure is released to a sufficient degree by some geological shift, then some of the gases bubble out and cause the magma to expand.

The word caldera comes from the Portuguese language, meaning "cauldron". See.a large, basinlike depression resulting from the explosion or collapse of the center of a volcano.The person "probably lived in the city but was not killed by the eruption" of the Loma,Despite its desert location some 160 kilometers northwest of Las Vegas, the 400-meter-high dormant,Dictionary, Encyclopedia and Thesaurus - The Free Dictionary,the webmaster's page for free fun content,First human remains found in El Salvador's 'Mayan Pompeii'.Will Trump and Perry revive proposed Yucca Mountain waste repository?Caldera OpenLinux Administration Software,Calderdale Primary Headteachers Association. If the expansion results in further relief of pressure, for example, by blowing crust material off the top of the chamber, the result is a very large gas explosion.According to analysis of earthquake data in 2013, the magma chamber is 80 km (50 mi) long and 20 km (12 mi) wide. According to the researchers, these maps could help predict when another supereruption occurs.Volcanic caldera in Yellowstone National Park in the United states,The northeastern part of Yellowstone Caldera, with the,West Thumb Lake is not to be confused with West Thumb Geyser Basin. n. A large crater formed by volcanic explosion or by collapse of a volcanic cone. Caldera volcano synonyms, Caldera volcano pronunciation, Caldera volcano translation, English dictionary definition of Caldera volcano. Contrary to some media reports, Yellowstone is not 'overdue' for a supereruption.Other media reports were more hyperbolic in their coverage.Studies and analysis may indicate that the greater hazard comes from hydrothermal activity which occurs independently of volcanic activity. The caldera formed during the last of three supereruptions over the past 2.1 million years: the Huckleberry Ridge eruption 2.1 million years ago (which created the,Volcanism at Yellowstone is relatively recent, with calderas that were created during large eruptions that took place 2.1 million, 1.3 million, and 630,000 years ago.

This can cause a chain reaction.
