During the night of 20 February 1979, the Sinila volcano of the Dieng Volcanic Complex erupted on the Indonesian island of Java in Central Java province. Over 175 people died, mainly due to gas poisoning in villages on the plateau near the Sinila crater. It was the fourth Sinila eruption since 1928, and the first one since 1951.This complex sits on a subduction zone between the Australian and Eurasian plates.
