Japan was hit by a 7.4-magnitude earthquake that hit 25 miles (40 kilometers) under the water off the coast of Miyagi prefecture. The quake that preceded last month’s tsunami was a 9.0-magnitude.
A strong aftershock and tsunami warning followed Thursday night nearly a month after a devastating earthquake and tsunami flattened the northeastern coast. Hundreds of aftershocks have been reported, since March 11, but few have been as strong as 7.0 magnitude.
