Japan Earthquake News: An earthquake with a preliminary magnitude of 7.5 struck off the northeastern coast of Japan on Monday afternoon, the Japan Meteorological Agency said. It warned of a tsunami as high as 3 metres in Iwate, Aomori and Hokkaido prefectures. The tremor had an epicentre in the Pacific Ocean and was 10 km deep, according to the JMA.
The operator of Tohoku Shinkansen bullet train says the service has been suspended between Tokyo station and Shin-Aomori station. It had been halted because of the earthquake, NHK reported.
Tokyo Electric Power Company says that it's checking to see if the quake has caused any problems at its Fukushima Daiichi and Daini nuclear power plants.
The Tohoku Electric Power Company is performing similar checks at its Onagawa nuclear power plant in Miyagi Prefecture and Higashidori nuclear power plant in Aomori Prefecture.
Minor tsunami observed at Miyako Port
A tsunami measuring 80 centimeters has hit Kuji Port in Iwate Prefecture, with water levels continuing to rise. A 40-centimeter tsunami was also observed at Miyako Port in Iwate Prefecture. Smaller waves have been recorded at several other locations: 30 centimeters at Hachinohe Port in Aomori Prefecture, and 20-centimeter tsunamis at Urakawa Town and Erimo Town in Hokkaido, as well as Ishinomaki Ayukawa in Miyagi Prefecture.
The Japanese government immediately established a task force at the crisis management center in the Prime Minister’s Office following the earthquake.
Why is Japan prone to earthquakes?
The quake measured an 'upper 5' on Japan's seismic intensity scale — strong enough to make it difficult for people to move around. In many cases, unreinforced concrete-block walls can collapse.
