A strong new earthquake rattled Japan's northeast Monday as the government urged more people living near a tsunami-crippled nuclear plant to leave, citing concerns about long-term health risks from radiation.
The magnitude 7.0 aftershock, which trapped some people in collapsed homes, came just hours after residents bowed their heads and wept in ceremonies to mark a month since a massive earthquake and tsunami killed up to 25,000 people and set off radiation leaks at the nuclear plant by knocking out its cooling systems.
"Even after a month, I still cry when I watch the news," said Marina Seito, 19, a student at a junior college who recalled being in a basement restaurant in Sendai when the original 9.0-magnitude earthquake hit on March 11. Plates fell and parts of the ceiling crashed down around her.
Officials said Monday's aftershock did not endanger operations at the tsunami-flooded Fukushima Dai-ichi nuclear complex, where power was cut but quickly restored. The epicenter was just inland and about 100 miles (160 kilometers) north of Tokyo.
But a nuclear safety official said repeated strong aftershocks - another large quake hit last Thursday - were slowing work at the plant, and said that if one of them were to spawn a tsunami, the complex would be just as vulnerable as on March 11.
