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.
Details and relief
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]
