Magnitude | 6.0 Mw |
Epicenter | 4°30′40″S 139°01′19″E / 4.511°S 139.022°E [1] |

Max. intensity | MMI VIII (Severe) [2] |
Casualties | 120 dead 120 injured |
The 1989 Irian Jaya earthquake struck Kurima District, Yahukimo Regency, Highland Papua, Indonesia – then Irian Jaya province – on August 1 with a moment magnitude of 6.0 and a maximum Mercalli intensity of VIII (Severe). Around 120 people were killed, mainly due to landslides and mudslides.
The earthquake struck at 9:17 local time [3] and measured Ms 5.7 [4] and 6.0 on the moment magnitude scale. [5] Its epicenter was located 299 km (186 mi) south of Jayapura; [6] the earthquake reached Wamena. [4] There were multiple aftershocks. [6]
The earthquake killed 120 people and left 120 injured; [4] all of the dead were recovered from the villages of Holuon, Pasema, and Soba. [3] Many of these deaths and injuries derived from landslides that covered two villages and disrupted sections of the Baliem River, practically flooding three villages [7] and depositing tons of mud. [3] One of these landslides was 200 m (660 ft) tall; [7] there were eleven in total. [8] A large portion of the dead consisted of Dhani tribesmen. [6]
Local authorities distributed food, blankets, clothing, and money to survivors. Helicopters supplied food and other relief supplies, [6] but they were slowed by cracks in the local airstrips. More than 25 survivors were treated for severe injuries and another 100 for less grave maladies. [3] Between 200 and 300 people were evacuated in the aftermath of the tremor, [3] [7] and 3,500 Hupla people were resettled at a lower altitude, thus moving them from their traditional settlements. [9]
The focal mechanism for the earthquake demonstrated reverse faulting. [4] The region around the epicenter has a history of powerful earthquakes. Between two earthquakes in 1976 and 1981, 1000 people died. [6] There have been large earthquakes in the region as recently as 2009 [10] and 2010. [11]
