JAKARTA, Indonesia (AFP) — A 6.2-magnitude earthquake hit off the coast of Indonesia’s Sumatra island early Monday, the United States Geological Survey reported.

The epicenter of the quake was 48 kilometers south-southeast of the city of Singkil in Aceh province, at a depth of 37 kilometers, USGS said.

It occurred around 6:30 a.m. local time, and USGS revised it up from its initial measurement at 6.0 magnitude with a 48 kilometers depth.

Indonesia’s Meteorology, Climatology and Geophysics Agency or BMKG also put it at 6.2 and said there was no threat of a tsunami, while the country’s disaster agency said there were no immediate reports of casualties or major damage.

“The earthquake caused people to panic. It was felt between 3 to 10 seconds in four districts in Aceh and North Sumatra province,” Abdul Muhari, a spokesperson for the BNPB disaster mitigation agency, said in a statement.
