Large numbers of earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region. Based on the records of the USGS, Indonesia has had more than 150 earthquakes with magnitude > 7 in the period 1901–2019.

Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by discoveries of Earth's tectonic plates, [1] seismotomography imaging technique, [2] observations using space satellites from outer space, [3] artificial intelligence (AI)-based ...
Variation of seismicity with depth across the Sunda Trench subduction zone, low-angle part is the Sunda megathrust – 2007 Bengkulu earthquakes mainshock shown by star. The Sunda megathrust is a fault that extends approximately 5,500 km (3300 mi) from Myanmar (Burma) in the north, running along the southwestern side of Sumatra, to the south of Java and Bali before terminating near Australia.

The first earthquake occurred at 11:10:26 UTC (18:10 local time) on 12 September 2007, and was an 8.4 M w earthquake on the moment magnitude scale. [2] It had a focal depth of 34 km, at , about 130 km southwest of Bengkulu on the southwest coast of Sumatra, Indonesia, and some 600 km west-northwest of Indonesia's capital city, Jakarta
If it were an intraslab earthquake occurring within the downgoing Australian plate as it subducts beneath the Sunda plate along the Sunda megathrust, the estimated moment magnitude (M w ) would be 7.4 to 8.0, with an epicenter near Batavia, and a focal depth of 100 km. [4] Modelling of the 1699 earthquake scenarios show that an intraslab ...

The 1861 Sumatra earthquake occurred on 16 February and was the last in a sequences of earthquakes that ruptured adjacent parts of the Sumatran segment of the Sunda megathrust. It caused a devastating tsunami which led to several thousand fatalities. The earthquake was felt as far away as the Malay peninsula and the eastern part of Java. [3]
