Magnitude 6.6 quake hits off Indonesia's Sumatra: USGS

A strong earthquake with a magnitude of 6.6 struck off northern Sumatra in Indonesia on Wednesday, the U.S. Geological Survey said, and there were warnings that a local tsunami was possible.

The Hawaii-based Pacific Tsunami Warning Center said there was no threat of a widespread, destructive tsunami after the quake, about 330 km (205 miles) southeast of Indonesia's Banda Aceh, but said there was a "very small possibility" of a local tsunami.
