A 7.3 magnitude earthquake hit just off of Japan’s coast early Saturday morning, which triggered tsunami alerts for the northeastern coast.
The quake occurred about 230 miles off of the Japanese coast at around 2 a.m. local time, according to ABC News, and was soon felt more than 300 miles away in Tokyo.
Citizens were informed to stay away from the coasts after the quake hit. The Japan Meteorological Agency put a tsunami warning out for the Iwate, Miyagi, Fukushima, Ibaraki and Chiba prefectures, reports the Japan Times.
The advisory was cancelled only a few hours later, but USA Today reports that small waves that were less than 3 feet high hit the cities of Soma, Kamaishi, and Ishinomaki-shi Ayukama.
According to the agency, Saturday’s quake was an aftershock of the 2011 quake, which struck the same area of Japan.
Japanese authorities evacuated the Fukishima power plant during the advisory, which was damaged in the 9.0 magnitude earthquake in 2011 that also killed more than 18,000 people. After workers were allowed to return early Saturday morning after the advisory was lifted, nothing abnormal was noticed in the plant.
There was no damage or serious injury reported after the quake, though one elderly woman reportedly fell from her bed during the quake and hit her head on the floor. She was taken to a nearby hospital to be treated for her minor injuries.
The earthquake was later downgraded from a 7.1 magnitude to a 6.8 magnitude earthquake. There were three different aftershocks that occurred following the quake, with the strongest measured at a magnitude of 5.5.
