TOKYO: Tsunami waves over a meter high hit central Japan on Monday (1st of Jan, 2023) after a series of powerful earthquakes that damaged homes, closed highways and prompted authorities to urge people to run to higher ground.
A major 7.5 magnitude earthquake struck the Noto region in Ishikawa prefecture around 4:10 pm (0710 GMT), the US Geological Survey (USGS) said.
Japan’s weather agency reported a succession of 21 quakes of 4.0 magnitude or stronger hitting the nation’s central region in just over 90 minutes.
Tsunami waves as high as 1.2 meters (four feet) hit Wajima port in Ishikawa prefecture at 4:21 pm (0721 GMT), about 10 minutes after the strongest jolt, the Japan Meteorological Agency (JMA) said.
“All residents must evacuate immediately to higher ground,” national broadcaster NHK said after the quakes.
Hazardous tsunami waves were possible within 300 kilometres (190 miles) of the quake’s epicentre along the coast, on the Sea of Japan side of Japan’s main island of Honshu, the Hawaii-based Pacific Tsunami Warning Center said.
But a much higher tsunami of five meters was expected to arrive in Noto in the same region, the JMA said.
The Japanese government said it was still assessing what damage had been caused and whether there had been any casualties.
Around 33,500 households around the epicentre, in Toyama, Ishikawa and Niigata prefectures, were without power, local utilities said.
Television reports showed a building on fire in Wajima city in Ishikawa and journalists said houses shook in central Tokyo.
A video clip posted on social media platform X showed lines of wooden houses toppled by the quakes, with walls and roofs caved in.
“This is the Matsunami district of Noto. We are in a horrible situation. Please come and help us. My town is in a horrible situation,” said a person heard in the video.
Sakhalin island and Vladivostok in Russia’s far east were on “alert” due to a possible tsunami risk after the quakes in Japan, officials said.
– ‘Lives above everything else’ –
The JMA said the Noto region experienced a rapid succession of quakes, with another 6.2 tremor hitting soon after the initial swarm, the USGS said.
The largest of the quakes prompted broadcasters to switch to special programming and make urgent calls for affected residents to leave for higher ground.
