JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) said there were no 6.3 magnitude (M) earthquakes in Bengkulu Province and not from the megathrust zone.
BMKG Earthquake and Tsunami Center Director Daryono said the earthquake that occurred on Friday, May 23 in the morning, came from the intraslab zone with a depth of 84 kilometers and did not have the potential to trigger a tsunami.
"This intraslab earthquake character has strong vibrations but does not cause basic deformation of the sea, so it does not cause a tsunami," Daryono said at a press conference in Jakarta, Friday, May 23, which was confiscated by Antara.
He added that this type of earthquake tends to have a high "stress drop", meaning that energy is released completely and usually not followed by aftershocks. As of this afternoon, no aftershocks have been detected.
The areas most affected were in Bengkulu City, but the tremors were also felt quite strongly in a number of areas such as Seluma in Bengkulu to Empat Lawang Regency, South Sumatra, and parts of western Lampung.

Daryono emphasized that people do not need to panic because scientifically the potential for aftershocks is very small.
"The energy has been released out," he said, adding that the intraslab zone has homogeneous rocks so that it is different from other active earthquake zones that have the potential to produce large aftershocks.
Previously, BNPB reported that until Friday, May 23 at 11.20 WIB, no casualties or injuries were reported.
However, the earthquake caused damage to 140 housing units and a number of public facilities in Bengkulu City, Central Bengkulu Regency, North Bengkulu, and Seluma Regency.
The impact of the damage varied from light to heavy with details of 50 damaged houses in Bengkulu City, two houses and one PAUD unit in Central Bengkulu, and 8 houses collapsed in Betungan Village. In addition, there are two schools, one mosque, one sub-district office, and one meeting hall that were damaged.
