A powerful earthquake has rocked the northern part of Indonesia's Sumatra island, killing at least one person and causing panic among others.

The U.S. Geological Survey says a 6.6-magnitude earthquake struck early Tuesday local time, about 100 kilometers southwest of the city of Medan. It was 110 kilometers deep and was felt in several communities in the region.

The mayor of the town of Subulussalam said a 12-year-old boy died in the quake, which also caused some material damage and sent frightened residents out in the streets.

No tsunami warning was issued as the quake was considered to be far enough from the coast.

Indonesia sits on the Pacific “Ring of Fire,” a series of fault lines that make the island nation prone to volcanic and seismic activity.
