6.3 magnitude earthquake reported off Andaman and Nicobar Islands

The approximate site of the earthquake that struck in the sea off India's Andaman and Nicobar Islands.

A 6.3 magnitude earthquake struck in the sea off India's Andaman and Nicobar Islands on Friday evening -- a week after a weaker quake shook the area, the India Meteorological Department said.

There was no immediate report of damage, and the U.S. Pacific Tsunami Warning Center did not issue any tsunami warnings for the area.

The quake was centered in the south Andaman Sea, about 113 kilometers east of Mohean on Katchal Island, one of the Nicobar Islands, the U.S. Geological Survey said. The USGS reported a different magnitude -- 6.5 -- than the Indian estimate.

The sea is one of the areas where search teams have been looking for missing Malaysia Airlines Flight 370 in recent days.

The temblor produced light to moderate shaking on Katchal, and light shaking on the rest of the Nicobars and, to the southeast, parts of Indonesia, the USGS reported.

Friday's earthquake comes seven days after a 5.5 magnitude quake struck in the same sea. That one -- which also brought no reports of damage -- was centered about 110 kilometers southeast of Mohean.
