The 1976 Papua earthquake occurred on 26 June with a surface-wave magnitude of 7.1 in Yahukimo Regency near the border with Pegunungan Bintang Regency, Highland Papua (then Irian Jaya), Indonesia. Total deaths for the event amounted to 422, including 70 who died in subsequent landslides.

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. [2] Papua is constantly plagued by landslides. [3]

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. [4]

The 1998 Papua New Guinea earthquake occurred on July 17 with a moment magnitude of 7.0 and a maximum Mercalli intensity of VIII (Severe). The event occurred on a reverse fault near the north coast region of Papua New Guinea, 25 kilometers (16 mi) from the coast near Aitape and caused a large submarine landslide which caused a tsunami that hit the coast, killing between at least 2,183 and 2,700 people and injuring thousands.

The first of the 2009 Sumatra earthquakes occurred on 30 September off the coast of Sumatra, Indonesia with a moment magnitude of 7.6 at 17:16:10 local time. The epicenter was 45 kilometres (28 mi) west-northwest of Padang, West Sumatra, and 220 kilometres (140 mi) southwest of Pekanbaru, Riau. Government and authorities confirmed 1,115 dead, 1,214 severely injured and 1,688 slightly injured. The most deaths occurred in the areas of Padang Pariaman (675), Padang (313), Agam (80) and Pariaman (37). In addition, around 135,000 houses were severely damaged, 65,000 houses were moderately damaged and 79,000 houses were slightly damaged. An estimated 250,000 families have been affected by the earthquake through the total or partial loss of their homes and livelihoods.

Shortly after midnight local time on January 20, 1981, eastern Indonesia was struck by an earthquake known as the 1981 Irian Jaya earthquake. Registering a moment magnitude of 6.7, it killed more than 300 people, damaging structures and buildings across the Irian Jaya province. Indonesia is highly active in terms of seismicity and volcanic eruptions, with a subduction zone and many faults. It is neighbored by several tectonic plates. Such earthquakes pose a significant threat to life in the area through earthquakes and also tsunamis.
