An earthquake occurred on September 2, 2009, at 14:55:01 local time in West Java, Indonesia.{{Cite anss|Java|2009|usp000h152|M 7.0 – Java, Indonesia|access-date=2 October 2018|mode=cs2}} 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).[http://regional.kompas.com/read/xml/2009/09/08/09584280/Korban.Tewas.Akibat.Gempa.Sudah.79.Orang "Korban Tewas Akibat Gempa Sudah 79 Orang"] Kompas newspaper, Sept 8, 2009{{cite web | url=https://cdn.bmkg.go.id/Web/Gempa-Signifikan-dan-Merusak-Per-Tahun-1821-2017.pdf | title=Katalog Gempabumi Signifikan Dan Merusak 1821–2017| publisher=Meteorology, Climatology, and Geophysical Agency | language=id | access-date=October 16, 2022}} 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.{{cite web|url=https://www.bloomberg.com/apps/news?pid=20601087&sid=a5lhxO3lwghE|title=Indonesian Quake Death Toll Reaches 64 as Rescue Work Continues|date=2009-09-04|accessdate=2009-09-04|publisher=Bloomberg News}}

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. Analysis of GPS data, tsunami run-ups and the effect of stress transfer compared to aftershock distribution supports a west-dipping reverse fault.{{Cite journal |last1=Gunawan |first1=E. |last2=Widiyantoro |first2=S. |last3=Marliyani |first3=G.I. |last4=Sunarti |first4=E. |last5=Ida |first5=R. |last6=Gusman |first6=A.R. |date=2019 |title=Fault source of the 2 September 2009 Mw 6.8 Tasikmalaya intraslab earthquake, Indonesia: Analysis from GPS data inversion, tsunami height simulation, and stress transfer |url=https://www.researchgate.net/publication/332755848 |journal=Physics of the Earth and Planetary Interiors |volume=291 |pages=54–61 |doi=10.1016/j.pepi.2019.04.004|bibcode=2019PEPI..291...54G |s2cid=155851594 }}

Another earthquake in the same subduction zone occurred only 5 days later in the ocean south of Yogyakarta.
