What formed Pinatubo?
subduction
It is a subduction-related volcano, formed by the Eurasian Plate sliding under the Philippine Mobile Belt along the Manila Trench to the west. Molten material related to the complex tectonics associated with the subducting slab, rises through the lithosphere and generates the volcanism typical of subduction.

More than 350 people died during the eruption, most of them from collapsing roofs. Disease that broke out in evacuation camps and the continuing mud flows in the area caused additional deaths, bringing the total death toll to 722 people. The event left more than 200,000 people homeless.
How long did Mount Pinatubo eruption last?
It lasted about five minutes, and the eruption column once again reached 24 km (15 mi). After three hours of quiet, seismic activity began, growing more and more intense over the next twenty-four hours, until a three-minute eruptive blast generated a 21 km (13 mi) high eruption column at 13:09 on June 14.
