JAKARTA, NNC - The Meteorology, Climatology and Geophysics Agency (BMKG) reported that a tectonic quake measuring 5.3 magnitude had occurred at 2:27 p.m. (Western Indonesian Time) on Wednesday, Sept 12, in the West Coast of Sumatra (Indian Ocean).

The earthquake's epicenter was located at coordinates 5.43 LS and 102.3 BT, or located at sea at a distance of 127 km southwest of Manna City, South Bengkulu District, Bengkulu Province at a depth of 40 km.

BMKG Earthquake and Tsunami Chief Rahmat Triyono says by looking at the epicenter's location and depth of the hypocenter, it appears that the quake is included in the shallow quake category, due to the subduction of the Indo-Australian Plate beneath the Eurasian Plate, precisely in the Megathrust zone which is the plate subduction zone located in Indian Ocean west of Sumatra.

"The convergence of the two plates forms a subduction zone which is one of the most active earthquake source regions in Sumatra. The results of the analysis of the source mechanism indicate that the earthquake was triggered by an descending enlargement with a combination of normal oblique," Rahmat told NNC on Wednesday, Sept 12.

The earthquake shock could be felt up to Liwa region on an intensity scale of II SIG-BMKG (III-IV MMI), South Bengkulu and Bengkulu City I-II SIG-BMKG (II-III MMI).

"So far there have been no reports of damages from the earthquake with no potential threat of tsunami," Rahmat said.

Until 2:50 p.m., the BMKG monitoring result did not show any aftershock activity. Residents are urged to remain calm and avoid fake news.
