MEDAN - A tectonic earthquake with a magnitude of 5.0 occurred in South Nias, North Sumatra, on Tuesday night at 20.16 WIB.
BMKG's Director of Earthquake and Tsunami, Diaryono, said the epicenter of the earthquake was located at coordinates 0.39 degrees Celsius and 98.62 degrees east longitude, or precisely located at sea at a distance of 91 km southeast of South Nias at a depth of 33 km.
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 under the Eurasian Plate.
The results of the analysis of the source mechanism show that the earthquake has an upward sliding mechanism.
Reported by ANTARA, the earthquake had an impact and was felt in the Sibolga and Humbang Hasundutan areas with an intensity scale of III MMI, and West Nias with an intensity scale of II MMI.
"The modeling results show that the earthquake has no potential for a tsunami," he said.
As of 20.30 WIB, the results of BMKG monitoring have not shown any aftershock activity.
