A tsunami warning followed a 7.4-magnitude aftershock off Japan on Thursday nearly a month after a 9-0-magnitude quake and tsunami flattened the northeastern coast.
The Japan meteorological agency issued a tsunami warning for a wave of up to a meter for a coastal area already torn apart by last month’s tsunami, according to the Associated Press.
Buildings as far away as Tokyo, 215 miles away, shook for about a minute from the quake, which reportedly 25 miles under the water off the eastern coast 90 miles from Fukushima, off the coast of Miyagi prefecture.
In Ichinoseki, inland from Japan’s eastern coast, buildings shook violently and all power was cut, leaving the city in darkness.
Hundreds of aftershocks have shaken the northeast region devastated by the March 11 earthquake, but few have been stronger than 7.0.
A Pacific Tsunami Warning Center evaluation of the quake said an oceanwide tsunami was not expected, according to the AP.
