Mayon

A pyroclastic flow sweeps down the SE flank of Mayon volcano in the Philippines on September 24, 1984. A thick column of ash rises above the surface of the moving pyroclastic flow, which was the largest of a series of pyroclastic flows that occurred during an eruption that began on September 9. Flow velocities of 50 m/sec were estimated from timed 35-mm photographs. The pyroclastic flow traveled 7 km from the summit vent, which is hidden behind the far left side of the ash column.
