Magnitude 6.6 quake hits off Indonesia's Sumatra - USGS

SYDNEY, July 25 (Reuters) - 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.
