Japan assesses damage from 7.5-magnitude earthquake in which dozens injured
Prime Minister Sanae Takaichi said an emergency task force had been set up to urgently review the situation.
Japan was assessing damage and cautioning people of potential aftershocks after a late-night 7.5-magnitude earthquake caused injuries, light damage and a tsunami in Pacific coastal communities.
At least 34 people were injured, one seriously, the Fire and Disaster Management Agency said. Most of them were hit by falling objects, public broadcaster NHK reported.
Prime Minister Sanae Takaichi told reporters an emergency task force had been set up to urgently assess the damage.
“We are putting people’s lives first and doing everything we can,” she said.
At a parliamentary session, Ms Takaichi pledged the government would continue its utmost effort and reminded people they had to protect their own lives.
The 7.5-magnitude quake struck around 11.15pm in the Pacific Ocean, around 50 miles (80km) off the coast of Aomori, the northernmost prefecture of Japan’s main Honshu island.
The US Geological Survey measured the quake at 7.6 magnitude and said it occurred 27 miles (44km) below the surface.
A tsunami of up to two feet, four inches (70cm) was measured in Kuji port in Iwate prefecture, just south of Aomori, and waves of up to 50cm struck other communities in the region, the Japan Meteorological Agency said.
NHK reported the waves had damaged some oyster rafts.
The agency had lifted all tsunami advisories by 6.30am.
Chief cabinet secretary Minoru Kihara said about 800 homes were without electricity and Shinkansen bullet trains and some local lines were suspended in parts of the region in the early hours of Tuesday.
East Japan Railway said bullet trains resumed operation in the region later on Tuesday.
Power was mostly restored by Tuesday morning, according to the Tohoku Electric Power Co.
About 480 residents sheltered at Hachinohe Air Base and 18 defence helicopters were mobilised for a damage assessment, defence minister Shinjiro Koizumi said.
About 200 passengers were stranded for the night at New Chitose Airport in Hokkaido, NHK reported.
And part of a domestic terminal building was unusable after parts of its ceiling cracked and fell to the floor, according to the airport operator.
The Nuclear Regulation Authority said about 450 litres (118 gallons) of water spilled from a spent fuel-cooling area at the Rokkasho fuel reprocessing plant in Aomori, but that its water level remained within the normal range and there was no safety concern.
No abnormalities were found at other nuclear power plants and spent fuel storage facilities, the NRA said.
JMA cautioned about possible aftershocks in the coming days. It said there was a slight increase in the risk of a magnitude 8-level quake and possible tsunami occurring along Japan’s north-eastern coast from Chiba, just east of Tokyo, to Hokkaido.
The agency urged residents in 182 municipalities in the area to monitor their emergency preparedness in the coming week, reminding them that the caution was not a prediction of a big quake.
Monday’s quake occurred just north of the coastal region where the magnitude 9.0 quake and tsunami in 2011 killed nearly 20,000 people and destroyed the Fukushima Daiichi nuclear power plant.
“You need to prepare, assuming that a disaster like that could happen again,” JMA official Satoshi Harada said.
Smaller aftershocks were continuing on Tuesday.
The US Geological Survey reported a magnitude 6.6 and later a 5.1 quake in the hours after the initial temblor.
