One was issued following another major quake in December. No major subsequent quake occurred.<\/p>\n<p>Earlier Monday, a magnitude 7.5 earthquake struck off the northeastern coast of\u00a0Japan\u00a0on Monday, as authorities urged residents to stay away from coastal areas where tsunami waves of up to three metres were expected.<\/p>\n<p>The biggest waves were forecast to hit Iwate and Aomori prefectures\u00a0at\u00a0the top\u00a0of\u00a0Japan&#8217;s main Honshu island, and the northern island of Hokkaido, authorities said.<\/p>\n<p>WATCH | Japan leads the world in earthquake response.

CBC\u2019s Johanna Wagstaffe<\/p>\n<p>There were no immediate reports of casualties or major damage, Japan&#8217;s \u2060top government spokesperson Minoru \u2060Kihara told a news conference as night fell \u200cin the capital, Tokyo.<\/p>\n<p>In the hour following the earthquake, which struck at 4:52 p.m. local time, tsunami waves as high as 80 centimetres had been detected, while warnings remained for waves as high as three metres. Japan&#8217;s Meteorological Agency (JMA) kept their tsunami alert in place while the Pacific Tsunami Warning Centre said the tsunami threat from the quake &#8220;has now passed.&#8221;<\/p>\n<p>Several port towns including Otsuchi and Kamaishi \u2014 both hard-hit by a massive earthquake and tsunami in 2011 \u2014 issued evacuation orders for thousands of residents, according to public broadcaster NHK.<\/p>\n<p>Prime Minister Sanae Takaichi said the government had set up an emergency task force and urged citizens in the affected areas to evacuate to safety.<\/p>\n<p>Big aftershocks anticipated<\/p>\n<p>Big aftershocks may occur in the following days and weeks, an official from\u00a0JMA said at a separate televised press conference.<\/p>\n<p>Ships sailed out of Hachinohe port in\u00a0Hokkaido in anticipation of the waves, footage aired on NHK\u00a0showed, as a &#8220;Tsunami! Evacuate!&#8221; alert flashed across the screen. A three-meter tsunami could cause damage to low-lying areas, flooding buildings, and anybody exposed would be caught in its currents, according to JMA.<\/p>\n<p>Bullet train services in Aomori were halted due to the tremors, Kyodo news agency reported.<\/p>\n<p>The quake measured an &#8220;upper 5&#8221; on\u00a0Japan&#8217;s seismic intensity scale \u2014 strong enough to make it difficult for people to move around and cause unreinforced concrete-block walls to collapse. The tremor had an epicentre in the Pacific Ocean and was 10 kilometres deep, JMA said.<\/p>\n<p>Located in the &#8220;Ring of Fire&#8221; of volcanoes and oceanic trenches partly encircling the Pacific Basin, \u00a0Japan\u00a0is one of the world&#8217;s most earthquake-prone countries, with a tremor occurring at least every five minutes.<\/p>\n<p>It accounts for about 20 per cent of the world&#8217;s earthquakes of magnitude 6.0 or more, such as the 2011 disaster that caused nuclear meltdowns at a Fukushima power plant.<\/p>\n<p>Another 7.5 magnitude quake in December left dozens injured.<\/p>\n<p>It&#8217;s been more than 15 years since a magnitude 9.0 earthquake and tsunami on March 11, 2011, ravaged parts of northern Japan, caused more than 22,000 deaths and forced nearly half a million people to flee their homes, most of them due to tsunami damage.<\/p>\n<p>Some 160,000 people fled their homes in Fukushima because of the radiation spewed from the tsunami-hit Fukushima Daiichi nuclear power plant. About 26,000 of them haven&#8217;t returned because they resettled elsewhere, their hometowns remain off-limits or they have lingering concerns about radiation.<\/p>\n","protected":false},"excerpt":{"rendered":"Listen to this article Estimated 4 minutes The audio version of this article is generated by AI-based technology.&hellip;\n","protected":false},"author":2,"featured_media":616414,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[43,44,41,39,42,40],"class_list":["post-616413","post","type-post","status-publish","format-standard","has-post-thumbnail","category-headlines","tag-headlines","tag-news","tag-top-news","tag-top-stories","tag-topnews","tag-topstories"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/616413","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=616413"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/616413\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/616414"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=616413"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=616413"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=616413"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
