The 1991 eruption of Pinatubo in the Philippines created a new caldera with an average diameter of 2.5 km. Caldera collapse occurred following the ejection of around 5 km³ of material in one of the world's largest eruptions of the 20th century and lowered the height of the volcano by about 300 m. This 1994 view from the NW shows a lake within the caldera and two small islands from a partially submerged lava dome that was erupted in 1992.
