Monday Earthquake Downgraded to 6.6 in Japan

Posted: Updated:

JAPAN (AP) - Japan's earthquake on Monday has been lowered to 6.6 in magnitude, according to the U.S. Geological Survey. A series of smaller quakes continued to shake the region. Residents in Tokyo also felt the jolts.

A tsunami warning issued by Japan's Meteorological Agency was later canceled.

Monday's initial 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.

Workers at the plant were asked to evacuate for a time, but later returned to resume their efforts to cool the troubled nuclear facility.

The Tohoku Electric Power Company said 220,000 households and businesses in Fukushima were without power after Monday's quake, which came a month after a deadly magnitude-9 quake and tsunami devastated the island nation.

To date, police have confirmed that 12,596 people have died as a result of the earthquake and tsunami on March 11th, another 14,747 are listed as missing or presumed dead.
