Geologists investigate a thick pyroclastic flow deposit on the ENE side of Parker volcano in southern Mindanao. Preliminary investigation of the eruptive deposits of this volcano revealed many similarities to those of Pinatubo. The flanks of both volcanoes are blanketed with thick pyroclastic flow deposits produced by powerful explosive eruptions.
