The SW avalanche valley, the smallest of four large radial valleys that extend from the summit of Manam to its lower flanks, is seen here in August 1972. During larger eruptions, pyroclastic flows and lava flows descend all four valleys and sometimes reach the coast. The unvegetated summit is emitting a plume.
