Details for: Pinatubo
The 1991 eruption of Pinatubo volcano in the Philippines created a new caldera with an average diameter of 2.5 km. Caldera collapse, which lowered the height of the volcano about 300 m, occurred following the ejection of nearly 10 cu km of tephra in one of the world's largest eruptions of the 20th century. This 1994 view from the NW shows a lake filling the caldera floor and two small islands from a partially submerged lava dome that was erupted in 1992.
