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.
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 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
The earthquake rupture propagated northwards until it reached the megathrust, triggering the second subevent along the Sunda megathrust itself. The strike-slip rupture probably represents slip on a pre-existing fracture zone , similar to the likely cause of the M 7.9 earthquake that struck about 1,000 km to the south on 18 June 2000 with a ...
The 1629 Banda Sea earthquake struck the Banda Sea, Indonesia on August 1. Its epicentre is believed to have been in the Seram Trough . A megathrust earthquake caused a 15 m (49 ft) tsunami, which was recorded to have affected the Banda Islands about 30 minutes after the quake.
