Clark Air Base on the ENE side of Pinatubo is the setting for this 14 June 1991 view, the day before the catastrophic eruption that caused collapse of the summit of the volcano. The evacuation of Clark Air Base was completed on 10 June. The light-colored peak in the center is the former 1,745 m summit, which is covered with ash from activity that had begun on 2 April and intensified strongly on 12 June. The high, dark ridge to the right is the NE rim of the 4 x 5 km Tayawan caldera of ancestral Pinatubo volcano.
