A 7.4-magnitude earthquake hit Japan at 11:32 p.m. local time on Thursday in the same area as the initial March 11 9.0-magnitude earthquake killing two people and injuring more than 100in the northeastern Japan.

The earthquake also knocked off power in parts of the region according to Japan's government broadcaster.

After the April 7 earthquake hit, Japanese authorities initially put out a tsunami warning and told people along the coastline to evacuate. However, there have been no evidence of tsunamis and the warning was lifted.

The aftershock caused no further damage to the already crippled Fukushima Daiichi nuclear plant, operator Tokyo Electric Power Co. (TEPCO) said. Cooling-down operations resumed after the fresh quake, the Kyodo news agency reported.

Following the quake, blackouts were seen all over Aomori, Iwate and Akita prefectures as well as several parts of Miyagi and Yamagata prefectures.
