Voluminous pyroclastic flows on 15 June 1991 descended all sides of Mount Pinatubo in the Philippines. 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. The dark hill at the center was completely surrounded by pyroclastic flows that traveled 14 km down this valley. Photo by Rick Hoblitt, 1991 (U.S. Geological Survey).
