Jakarta (ANTARA) – The Meteorology, Climatology and Geophysics Agency (BMKG) reported that the 6.4 magnitude tectonic earthquake on the west coast of Aceh on Saturday morning did not cause a tsunami.
“There is no impact from the tsunami, and the sea level also does not show any increase. There is a sea level observation tool, and it is indicated that it does not there is no significant sea level change,” said BMKG geophysics deputy Suko Prayitno Adi. said during a virtual press conference on post-earthquake development in Aceh, followed here, on Saturday.
Adi noted that the earthquake was triggered by Aceh-Andaman Megathrust plate subduction activity, in line with active Megathrust activity in the West Sumatra region.
Based on observations of the epicenter and the depth of the hypocenter, the earthquake that struck was a shallow type of earthquake that had a thrust fault mechanism, Adi explained.
He said the map of the estimated shock level reached the Modified Mercalli Intensity (MMI) IV-V scale which could potentially cause damage.
As of 9:00 a.m. local time on Saturday, Adi had not yet received any reports of casualties from the incident.
“If we look at the intensity, the possibility of damage is only minor. So far, no casualties have been reported,” he noted.
BMKG reported that the earthquake was felt at MMI IV in Meulaboh, South Aceh and Nagan Raya regions.
The earthquake was also felt at MMI III by residents of Aceh Besar, Banda Aceh, Takengon, Bener Meriah and Simeulue.
“The earthquake sounded like a passing truck,” he said.
He noted that the earthquake was also felt at MMI II in Pidie, Idi, Bireun, Langsa and Aceh Tamiang.
“Several people felt the earthquake. Light objects that were hanging also swayed. So far, no damage from the earthquake has been reported,” Adi noted.
At 8:10 a.m. local time, BMKG monitoring results indicated two aftershocks, with the largest magnitude of 2.7.
The agency reminded the public to remain calm but vigilant as aftershocks are likely to occur.
“People whose homes have been damaged or partially damaged are advised not to stay in their homes. Buildings may suffer more severe damage and even collapse due to aftershocks,” Adi said.
He also warned the public to beware of hilly areas, with steep cliffs, as strong aftershocks could trigger landslides and rock collapses.
“People are urged not to believe false information about predictions of a bigger earthquake and tsunami,” Adi said.
As previously reported, a tectonic earthquake, with a magnitude of 6.4, at 03:53 local time, with the epicenter at 3.75° north latitude; 95.97° east longitude, at sea, 46 kilometers southwest of Meulaboh, Aceh Barat, at a depth of 53 kilometers, shook the west coast of Aceh.
Aceh experienced a major earthquake which triggered a tsunami on December 26, 2004, with a magnitude of 9 which resulted in the death of 283,100 people, the disappearance of 14,100 people and the displacement of 1,126,900 people.
Another earthquake struck on March 28, 2005, with a magnitude of 8.6, killing 1,303 people, injuring more than 340, and damaging more than 300 buildings.
On April 7, 2010, the BMKG recorded an earthquake of magnitude 7.6 which left five seriously injured, 17 slightly injured, 64 houses seriously damaged, 275 houses moderately damaged and 824 houses slightly damaged.
