Pinatubo

Voluminous pyroclastic flows on June 15, 1991, from Mount Pinatubo in the Philippines, swept all sides of the volcano. The flat, light-colored areas in the foreground are pyroclastic-flow deposits that filled the Marella River valley on Pinatubo's SW flank to a depth of 200 m, more than the height of the Washington Monument. The dark hill at the center was completely surrounded by pyroclastic flows, which traveled 14 km down this valley.
