Tokyo (CNN): Fires burned in northeastern Japan Monday evening after a powerful earthquake shook the region, sending a landslide into Iwaki City, authorities said.
A preliminary estimate put the quake’s magnitude at 7.1, which was later lowered to 6.6, according to the U.S. Geological Survey. Residents in Tokyo also felt the jolts.
A tsunami warning issued by Japan’s Meteorological Agency was canceled.
The quake was centered about 164 kilometers (101 miles) northeast of Tokyo, or about 50 kilometers (31 miles) southwest of the crippled Fukushima Daiichi nuclear plant, according to the USGS.
Workers at the plant were asked to evacuate.
The Tohoku Electric Power Company said 220,000 households and businesses in Fukushima where without power after Monday’s quake.
