Tokyo, March 17, 2022, SPA -- Tens of thousands of Japanese households remained without power on Thursday morning after a magnitude 7.4 quake struck shortly before midnight, throwing a swathe of northeastern Japan into darkness, severing key transportation links and killing four, Reuters reported. About 300 km (186 miles) south of Fukushima, areas of the capital Tokyo lost power immediately after the quake, though most regained it within three hours. Prime Minister Fumio Kishida said four people had died and that the government would be on high alert for the possibility of further strong tremors over the next two to three days. At least 107 people were reported injured, several seriously, with 4,300 households also still without water by mid-morning. Residents of one Fukushima city formed a long queue to fill up plastic tanks with water for use at home. The quake, initially measured at magnitude 7.3 but later revised to 7.4 by the Japan Meteorological Agency, hit at 11:36 p.m. local time (1400 GMT) just off the coast of Fukushima prefecture at a depth of 60 kilometres. --SPA 10:48 LOCAL TIME 07:48 GMT 0007 www.spa.gov.sa/w1708387
