Tokyo, Dec 9 || At least 30 people were injured after a powerful 7.5-magnitude earthquake struck Japan, triggering tsunami waves that reached heights of up to 70 centimetres along the Pacific coast, local media reported on Tuesday, quoting the government.
The Japan Meteorological Agency said the quake struck at 11:15 p.m. local time on Monday off the eastern coast of Aomori Prefecture at a depth of 54 kilometres.
The agency warned that the tremor could be followed by another earthquake of similar or even higher magnitude in the same region in the coming days, News reported.
Prime Minister Sanae Takaichi urged residents in the affected regions to remain alert for updates from local authorities and the weather agency over the next week or so, and to make preparations for a possible subsequent quake, including by securing furniture and household items.
