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 ...

Compared to normal arc-related volcanic eruptions, the formation of a volcanic caldera is a relatively atypical event. During caldera formation a series of large volumes of magma are erupted, reducing ...

Las Cañadas caldera at Tenerife, Canary Islands, is the result of different episodes of caldera collapses, associated to large explosive eruptions that triggered several landslides that modified the ...

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 ...
