Caldera formation arises when large volumes of magma are evacuated from a sub-surface reservoir, leading to gravitational collapse of the overlying rock into the evacuated space. The process begins ...

A spectacular proof of our planet's activity, calderas are huge topographic depressions, similar to flat-bottomed craters, with a diameter of several tens of kilometres. They are formed by large ...

The McDermitt Caldera is 16.4 million years old, and this specific caldera formation measures 45 kilometers in length and 35 kilometers in circumference. The McDermitt Caldera eruption is believed to ...

An international team of scientists co-led by Dr. Steffen Kutterolf from GEOMAR Helmholtz Center for Ocean Research Kiel has found evidence of a historical submarine eruption of the Kameni volcano on ...

Below that, they found what they describe as the caldera's basement—a dense rock formation that the research team suggests serves as the backbone of the caldera. In their work, the researchers found ...

New research indicates that a volcano near Naples, Italy might be in the early stages of gearing up for an eruption large enough to change the area’s landscape. In the study, researchers found that ...

The Bárdarbunga eruption on Iceland has broken many records. The event in 2014 was the strongest in Europe since more than 240 years. The hole it left behind, the so-called caldera, is the biggest ...

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the ...

Calderas are huge topographic depressions formed by large volcanic eruptions. They sometimes experience an inflation of their floor of up to a kilometer, caused by magma injection. This process, ...
