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 ...
Plate tectonic setting of Sunda megathrust USGS map showing rupture area of the 1833 quake. The 1833 Sumatra earthquake occurred on November 25 at about 22:00 local time, with an estimated magnitude in the range of 8.8–9.2 M w . It caused a large tsunami that flooded the southwestern coast of the island. There are no reliable records of the ...

The 1797 Sumatra earthquake occurred at 22:00 local time on 10 February. [1] It was the first in a series of great earthquakes that ruptured part of the Sumatran segment of the Sunda megathrust . It caused a damaging tsunami that was particularly severe near Padang , where a 150–200 t (170–220 short tons) English ship was driven 1 km (0.62 ...
A major earthquake in Yogyakarta on 27 May 2006 killed 5,716 people. [10] A magnitude 7.7 earthquake caused a tsunami around west and central Java on 17 July 2006 and killed 668 people. [11] The 2009 Sumatra earthquakes on 30 September caused severe damages in Western Sumatra, killing around 1,110 people and leaving 2,180 injured. [12]
The earthquake occurred in the Sunda Strait segment of the Java Trench. The magnitude of the earthquake was estimated at M w 8.5, although some experts provided a range of M w 8.0–8.5. [3] However, seismologists also attribute the earthquake to shallow crustal faulting associated with a back-arc thrust fault running along the island.
