Magnitude 6.0 Earthquake on coast of East Kalimantan, Borneo.

The United States Geological Survey recorded a Magnitude 6.0 Earthquake at a depth of 9 km on the coast of the Indoneasian province of East Kalimantan on Borneo slightly after 2.45 am local time on Monday 21 December 2015 (slightly after 6.45 pm on Sunday 20 December GMT). People have reported feeling the quake across East Kalimantan and Malaysian Sabah, though there are no reports of any injuries or significant damage.

The approximate location of the 21 December 2015 East Kalimantan Earthquake. Google Maps.

Borneo forms part of the Sunda Plate, a breakaway section of the Eurasian Plate caught between the converging Eurasian, Indo-Australian, Philippine and Pacific Plates. It is being pushed to the north by the movement of the Indo-Australian Plate to the south (which is being subducted beneath the Sunda Plate along the southern shores of the islands of Java and Sumatra), and to the west by the movement of the Philippine Plate to the east (which is being subducted beneath the Sunda Plate to the east of the Philippines). To the southeast of the island the Moluca and Banda Plates, which together form the island of Sulawesi, are being subducted beneath the Sunda Plate along the southeastern shore of Borneo, pushing the island to the northwest, and creating further tectonic stresses.

Witness accounts of Earthquakes can help geologists to understand these events, and the structures that cause them. The international non-profit organization Earthquake Report is interested in hearing from people who may have felt this event; if you felt this quake then you can report it to Earthquake Report here.
