Incandescent blocks roll down the SW flanks of Mayon on 18 May 1978, seen from near Camalig on the SW flank. During the eruption a lava flow traveled a distance of more than 4 km over the top of the 1968 lava flow to about 550 m elevation. The 1978 eruption began on 7 March and continued through the summer.
