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 Bardarbunga 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 ...

One of the most common features found at large volcanoes are calderas, formed by the collapse of the land due to eruption. The scale of these features varies a lot depending on if you're on Earth or ...

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 ...

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 ...

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, ...

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 ...
