TEMPO.CO, Jakarta - The Meteorology, Climatology, and Geophysics Agency (BMKG) conducted an analysis and parameter changes to the earthquake that rocked Bengkulu in the early hours of today, February 21, 2023, at 03:13:51 western Indonesian time (WIB).

Head of the agency’s quake and tsunami center, Daryono, said the Indian Ocean of Sumatra’s west coast, Seluma, Bengkulu was rocked by a tectonic quake with an updated magnitude of 5.2.

Its epicenter was located at 4.39° South Latitude and 102.08° East Longitude, or precisely at sea, 59 kilometers south of Bengkulu City, and was at a depth of 56 kilometers.

"Taking into account the epicenter and the depth, the quake was a shallow one triggered by the subduction activity of the Indo-Australian Plate," said Daryono. The analysis also indicated that the quake has a thrust fault mechanism.

The tremor was felt in Seluma with an intensity scale of III MMI as well as in Manna and Bengkulu City with an intensity scale of II-III MMI.

There was no report of damages caused by the quake thus far. The modeling results also showed that the quake had no potential to generate a tsunami. As of 03:40 WIB, the agency did not detect any aftershocks.

On Monday, February 20, the BMKG confirmed that a subduction activity of the Indo-Australian plate triggered an earthquake with a magnitude of 5.2 in Simeulue, Aceh.
