Gunung Api volcano is seen here in an aerial view from the south on May 19, 1988. The narrow peninsula at the left-center is the terminous of a still-steaming lava flow that was erupted from a vent low on the SW flank beginning on May 9. Another flow erupted from a vent at about 150 m elevation on the SW flank also reached the sea immediately to the west. The May 9 vents were located along an arcuate N-SSW-trending fissure that cut across the summit of the volcano.
