A 6.2-magnitude earthquake struck off the central Indonesian island of Sulawesi on Wednesday

A 6.2-magnitude earthquake struck off the central Indonesian island of Sulawesi on Wednesday, according to the U.S. Geological Survey (USGS), sending panicked residents running from their homes.

The USGS initially reported the quake's magnitude at 6.5 but later revised it down.

The quake struck in the Molucca Sea between Sulawesi and the Maluku chain of islands, but Indonesian officials said there was no threat of a tsunami.

The tremor was felt in the major cities of Manado and Gorontalo in northern Sulawesi.

"People in Manado felt the quake and ran from their homes," national disaster agency spokesman Sutopo Purwo Nugroho said.
