Evacuate as quickly as possible. Waves can hit repeatedly. Continue to evacuate until all warnings are lifted.<\/p>\n NKH added in its report:<\/p>\n double quotation markIf you are in the affected areas, keep away from coasts and river mouths which could overflow. Continue to evacuate until all advisories are lifted.<\/p>\n It said that while there may be some changes to the sea level, \u201cthere is no threat of tsunami damage,\u201d adding:<\/p>\n double quotation markPeople in the affected areas must evacuate immediately. Escape to a higher, safe location right away.The time of the tsunami\u2019s arrival is just an estimate.<\/p>\n Waves could actually arrive sooner or later.

The disaster killed almost 20,000 people, most of whom were swept away by the tsunami.<\/p>\n Share<\/a><\/p>\n It\u2019s 15 years since the much more powerful magnitude 9.0 earthquake and tsunami on March 11, 2011, ravaged parts of northern Japan<\/a>. As Associated Press reports, it caused almost 20,000 deaths and forced nearly half a million people to flee their homes.<\/p>\n 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\u2019t returned because they resettled elsewhere, their hometowns remain off-limits or they have lingering concerns about radiation.<\/p>\n Share<\/a><\/p>\n Updated at\u00a005.09 EDT<\/p>\n There are no nuclear power plants currently in operation in Hokkaido and Tohoku regions but Hokkaido Electric Power Co and Tohoku Electric Power Co have a number of shutdown nuclear power plants there.<\/p>\n Tohoku Electric said it was checking the impact of the earthquake and tsunami on its Onagawa nuclear power plant.<\/p>\n Share<\/a>People in affected areas urged to evacuate<\/p>\n The strength of the earthquake has been revised up to 7.5 and the biggest waves due to the tsunami are expected in Iwate, Aomori and Hokkaido prefectures, authorities said.<\/p>\n Reuters reported that 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 Broadcaster NHK showed ships sailing out of Hachinohe port in Hokkaido in anticipation of the waves, as an alert \u2019Tsunami!
