Tsunami warning lifted after Japan quake

TOKYO - Three strong earthquakes rattled southwestern Japan islands on Friday, but there were no immediate reports of injury or damage.

Japan's Meteorological Agency at one point warned that a small tsunami was possible, but later said no such waves had developed.

The strongest quake, with a preliminary magnitude of 6.7, struck at 10:46 a.m. Two other quakes, each with preliminary magnitudes of 6.2, struck shortly before and then after the larger temblor, the agency said.

All the quakes struck near the island of Miyakojima, 1,130 miles southwest of Tokyo, part of the Ryukyu islands chain that stretches southwest toward Taiwan.

Japan is one of the world's most earthquake-prone countries.
