A powerful earthquake off the northeast Japanese shore Tuesday sent residents fleeing to higher ground and prompted worries about the Fukushima nuclear power plant destroyed by a tsunami five year ago. Lines of cars were seen snaking away from the coast in the pre-dawn hours after authorities issued a tsunami warning and urged residents to seek higher ground immediately. The warning was lifted nearly four hours later. The magnitude 7.4 earthquake struck in the same region that was devastated by a tsunami in 2011, killing some 18,000 people. There were reports of minor injuries and damage, Japanese broadcaster NHK said. The earthquake shook buildings in Tokyo, 240 kilometers (150 miles) southwest of the epicenter.
NHK also showed one person’s video of water rushing up a river or canal, but well within the height of the embankment. It was eerily reminiscent of the 2011 disaster, when much larger tsunamis rushed up rivers and overflowed, wiping away entire neighborhoods.
On Tuesday, tsunami waves were recorded along the coast. The highest one was 1.4 meters (4.6 feet) in Sendai Bay. Hours later, the Japanese government lifted its tsunami warning. “The tsunami advisory has been lifted,” the Japan Meteorological Agency said in a statement released at 12:50 pm (0350 GMT) on its website.
The operator of the Fukushima Dai-ichi plant said there were no abnormalities observed at the plant, though a swelling of the tide of up to 1 meter was detected offshore. The plant was swamped by the 2011 tsunami, sending three reactors into meltdown and leaking radiation into the surrounding area. The plant is being decommissioned but the situation remains serious as the utility figures out how to remove still-radioactive fuel rods and debris and what to do with the melted reactor cores.
Plant operator TEPCO said a pump that supplies cooling water to a spent fuel pool at the nearby Fukushima Dai-ni plant stopped working, but that a backup pump had been launched to restore cooling water to the pool. Both plants are run by Tokyo-based TEPCO.
Naohiro Masuda, head of TEPCO’s decommissioning unit, said he believes that the pump was shut off automatically by a safety system as the water in the pool shook. He said decommissioning work at the destroyed Dai-ichi plant had been temporarily suspended because of the earthquake. The US Geological Survey measured the magnitude at 6.9.
For many, the early morning jolt brought back memories of the 2011 earthquake and tsunami. “I remembered 3/11,” Kazuhiro Onuki said by phone, referring to the March 11 date of the 2011 disaster. “It really came back. And it was so awful. The sways to the side were huge. But nothing fell from shelves.”
The 68-year-old former librarian is from Tomioka, a town that became a no-go zone because of radiation contamination. He was staying at what he calls one of his temporary homes on Tuesday. “I felt again that we should not have nuclear power,” he said.
