Powerful 7.5-magnitude earthquake strikes off Japan, tsunami alert issued

TOKYO, April 20, (AP): A powerful earthquake struck off the northern Japanese coast, and the Japan Meteorological Agency issued a tsunami alert in the region. The quake registering a preliminary magnitude of 7.5 occurred off the coast of Sanriku in northern Japan at around 4:53 p.m. (0753 GMT), at a depth of about 10 kilometers (6 miles) below the sea surface, the agency said.

Japan’s NHK public television said a tsunami of up to 3 meters (10 feet) could hit the area shortly. It's 15 years since a magnitude 9.0 earthquake and tsunami on March 11, 2011, ravaged parts of northern Japan, caused more than 22,000 deaths and forced nearly half a million people to flee their homes, most of them due to tsunami damage.

Some 160,000 people fled their homes in Fukushima because of the radiation spewed from the tsunami-hit Fukushima Daiichi nuclear power plant. About 26,000 of them haven’t returned because they resettled elsewhere, their hometowns remain off-limits or they have lingering concerns about radiation.
