An earthquake occurred on September 2, 2009, at 14:55:01 local time in West Java, Indonesia.^[1] The magnitude 7.0 earthquake killed at least 81 people, injured over 1,297, and displaced over 210,000 (including more than 140,000 in Tasikmalaya regency).^[2]^[3] The quake was felt in the capital Jakarta, although damage there was minimal, and it was Indonesia's deadliest earthquake since the 2006 Pangandaran earthquake and tsunami.^[4]

Cause

The earthquake's focus lies close to the major fault plane where the Indo-Australian plate is being subducted beneath the Eurasian plate. However, the focal mechanisms determined for this event shows reverse faulting at a high angle to the trend of the subduction zone and it has been suggested that the cause was deformation within the descending slab.^[1] Analysis of GPS data, tsunami run-ups and the effect of stress transfer compared to aftershock distribution supports a west-dipping reverse fault.^[5]

Another earthquake in the same subduction zone occurred only 5 days later in the ocean south of Yogyakarta. This newer quake (magnitude 6.2)^[6] is considered to be related to the West Java earthquake.^[7]

Damage

Buildings in Bandung and Tasikmalaya, the town closest to the epicenter, were damaged, and hundreds of people were injured.^[8] An estimated 18,300 homes and offices were earlier thought to have been damaged. This figure later rose to 87,000.

The quake was felt in Jakarta, Indonesia's capital;^[9] causing evacuation in many office buildings and hotels. Several office buildings along major thoroughfares in Central Jakarta suffered damage.

At least 11 houses were covered by a landslide in Cianjur.^[10]

Around 37 inhabitants, including 13 children, of Cikangkareng were affected by a landslide caused by the quake and are thought to have been buried beneath rubble.^[11] The area has become a breeding ground for voyeurs who are flocking to the area to take photographs of the destruction and victims.^[12]

At least one hospital was destroyed by the quake.^[13]

Victims

Confirmed death tolls by area were issued by The Jakarta Post on 4 September.^[14]

They provided food and clothing as well as meals for the breaking of fast.^[17]
