JAKARTA - An earthquake with a magnitude (M) of 5.8 that was updated to M 5.6 hit the Mentawai Islands triggered by the subduction activity of the Indo-Australian plate.
Head of the BMKG Earthquake and Tsunami Center, Daryono, said that the 34-kilometer earthquake was located at sea at a distance of 167 km northwest of the Mentawai Islands, West Sumatra (West Sumatra).
"By paying attention to the location of the epicenter and the depth of the hypocenter, the earthquake that occurred was a shallow type of earthquake due to the subduction activity of the Indo-Australian plate hitting the Eurasian plate," he said in Jakarta, Tuesday,
He added that the results of the analysis of the source mechanism showed that the earthquake had a thrust fault mechanism.
"The modeling results show that this earthquake has no potential for a tsunami," he said.
Daryono said the earthquake that occurred on Tuesday, June 20 at 15.39 WIB was located at coordinates 1.03 south latitude and 98.42 east longitude.
