Background

Indonesia lies within the Pacific Ring of Fire, a sector of the Pacific where several tectonic plates intersect. This movement between the plates results in extremely high volcanic and seismic activity. Papua is constantly plagued by

Damage and casualties

Directly after the earthquake the casualty count was assessed as 350 dead. However, landslides soon occurred in the affected area, leading to 72 more casualties, and 5,000–9,000 were missing and assumed dead after the landslides. A total of six villages were demolished in the area. The west sector of Irian and eastern New Guinea also reported that the earthquake was felt significantly in their region.
