A 6.4-magnitude earthquake struck Indonesia's North Sumatra province on Saturday, according to the country's meteorology agency BMKG. The quake occurred at a depth of 168 kilometers, with its epicenter located on land about 11 km southeast of Simalungun. BMKG confirmed there was no tsunami threat and no immediate reports of aftershocks or damages. Tremors were felt in Tebing Tinggi, Kabanjahe, and Limapuluh areas.
This event follows a more powerful 7.7-magnitude earthquake that struck off eastern Indonesia on the same day, resulting in at least 38 fatalities and prompting a brief tsunami warning that was later lifted. The earlier quake caused significant damage, including collapsed buildings and landslides, with power outages hampering rescue efforts.
Another report stated the 6.4-magnitude earthquake's epicenter was located at sea at a depth of 13 kilometers, 61 km southeast of Sinabang, Aceh, and advised the public to remain cautious of possible aftershocks. A 5.0-magnitude earthquake also struck Southwest Maluku Regency earlier that Tuesday.
