Japan Braces for Possible Megaquake After 3rd Consecutive Quakes, No Tsunami Threat

Japan has been rocked by a series of powerful earthquakes, with the latest tremors measuring 6.5 magnitude on the Japanese scale (5.9 on the Richter scale) striking eastern Aomori and Hokkaido prefectures on Wednesday. The depth of the quake was 30 kilometers. The country has faced three consecutive days of earthquakes, with a 7.6 magnitude quake on Monday and a 6.7 magnitude quake on Tuesday. The Japan Meteorological Agency (JMA) has issued a rare 'megaquake advisory' following Monday's devastating quake, warning of an elevated risk of a powerful magnitude-eight-plus quake within the next week. According to authorities, Monday's quake has injured 51 people, with the number expected to rise. The JMA has advised residents in coastal areas to stay alert, be prepared with emergency kits, and evacuate quickly if needed. The agency cited the increased seismic risks along the Hokkaido-Sanriku coast, where the Pacific Plate dives beneath Japan, forming the Japan Trench and Chishima Trench. This pattern is reminiscent of the 2011 magnitude 9.0 megaquake, which was preceded by tremors of magnitude 7.3 in the same zone just two days earlier. The JMA has highlighted the possibility of a massive tsunami reaching the area or experiencing strong shaking if a large-scale earthquake occurs in the future. No tsunami threat has been issued following the latest earthquake, but residents are advised to remain vigilant.
