Caldera

  • mount mazama's eruption timeline, an example of caldera formation

    a caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber/reservoir in a volcanic eruption. when large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. the ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a massive depression at the surface (from one to dozens of kilometers in diameter). although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. only seven caldera-forming collapses are known to have occurred since 1900, most recently at bárðarbunga volcano, iceland in 2014.[1]
