Japan Hit by New 7.4 Quake
Japan was rattled by a strong aftershock and tsunami warning Thursday night nearly a month after a devastating earthquake and tsunami flattened the northeastern coast.
The Japan meteorological agency issued a tsunami warning for a wave of up to one meter. The warning was issued for a coastal area already torn apart by last month's tsunami.
Officials say Thursday's quake was a 7.4-magnitude and hit 25 miles (40 kilometers) under the water and off the coast of Miyagi prefecture. The quake that preceded last month's tsunami was a 9.0-magnitude.
Buildings as far away as Tokyo shook for about a minute.
