T
he Meteorology, Climatology and Geophysics Agency (BMKG) has recorded an increase in seismic activity around a local fault in Pagar Alam city, South Sumatra, beginning on Feb. 27.
The most recent tremor was confirmed to have occurred on Sunday morning with a magnitude of 2.1 on the Richter scale.
Earlier, a total of 10 minor earthquakes occurred, including two earthquakes on Feb. 27, one earthquake on March 4, two earthquakes on March 6 and four earthquakes on March 9. The magnitude of the earthquakes ranged from 1.5 to 3.2.
“We’re still focusing on monitoring the fault’s activity because it’s uncommon. Hopefully, no major earthquake will follow,” BMKG’s Kepahiang-Bengkulu Geophysics Station researcher Sabar Ardiansyah told The Jakarta Post on Sunday.
He went on to explain that small earthquakes rarely occurred successively at the location.
The fault is the Manna segment, a part of the larger Sumatra fault. The segment stretches from South Bengkulu regency to the west side of Mount Dempo between Tanjung Sakti Pumu district and Pagar Alam city and extends to the hills in Semendo district of Muara Enim regency.
