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 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 ...

Magma chambers function both as repositories for melt rising through the crust and as reservoirs that feed individual volcanic eruptions. During silicic caldera-forming eruptions, these functions ...

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 ...

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 ...
