6.6-Magnitude Earthquake Hits Indonesia's Sulawesi Monday May 29,2017

A shallow, 6.6-magnitude earthquake hit inland on the central Indonesian island of Sulawesi on Monday May 29,2017, US seismologists said.

The quake hit at a depth of nine kilometres (six miles) at 10:35 pm (1435 GMT), 80 kilometres southeast of the city of Palu, USGS said.

Muhammad Guntur, who lives on the outskirts of Poso, east of the epicentre, said it was felt strongly.

"People are panicking here. We are now all gathered outside of our houses," he told AFP. "The electricity is off here."

Indonesia sits on the Pacific "Ring of Fire" where tectonic plates collide, causing frequent seismic and volcanic activity.
