A warning of a tsunami reaching as high as 3.3 feet has been issued in Japan after a powerful earthquake jolted the north-west of the country.
Huge tremors were felt on the west coast of Honshu on Tuesday and an alarm was immediately been put into effect along the coast of the north-western prefectures of Yamagata, Niigata and Ishikawa.
The earthquake was measured at 6.8 magnitude, according to Japan’s Meteorological Agency and was located off the western coast of Yamagata, around 30 miles south-west of the city of Sakata. The body said the quake’s epicentre was fairly shallow, about six miles below the sea’s surface. However, shallow earthquakes usually cause more damage to the Earth’s surface. Around 9,000 households in Yamagata and Niigata lost power, according to Tohoku Electric Power Co.
The bullet train service, which connects Tokyo and Niigata city, was suspended in parts of the region due to power cuts and for safety checks. All seven reactors at the Kashiwazaki-Kariwa nuclear plant in Niigata were off line and no abnormalities were reported. Chief Cabinet Secretary Yoshihide Suga said an emergency response team was set up at the Prime Minister’s Office to assess the extent of injuries and damage. He urged residents of the affected areas to be prepared for possible aftershocks, as many were evacuated to safe areas. An elderly man suffered a minor foot injury in Murakami city, where strong shaking was reported, public broadcaster NHK said.
