Pinatubo

Lahars from Pinatubo volcano fill the broad Santo Tomás River valley SW of the volcano. Erosion along the south bank of the river has cut into the town of San Rafael. This photo was taken a month after the end of the 1991 eruption. Lahars produced by the redistribution of thick deposits of ashfall and pyroclastic flows caused extensive longterm economic devastation and were expected to continue for as long as a decade after the eruption.
