\n Now residents in 182 towns across seven prefectures have been urged to be on alert for a potential stronger earthquake and to confirm evacuation routes and shelters, Japan\u2019s national broadcaster NHK reported.\n <\/p>\n
\n The megaquake advisory is not a prediction, but officials from Japan\u2019s Cabinet Office and the Japan Meteorological Agency said there was a 1% chance of an earthquake of magnitude 8 or stronger striking along two deep sea trenches in the Pacific in the next week, compared to a 0.1% chance during normal times, the Associated Press<\/a> reported.\n <\/p>\n \n A similar advisory was issued following a 7.5-magnitude earthquake that struck off Japan\u2019s northeastern coast in December 2025<\/a>, but a larger quake did not occur.\n <\/p>\n \n \u201cThe government will do our utmost in case of an emergency,\u201d Japanese Prime Minister Sanae Takaichi told reporters Monday, the AP reported.\n <\/p>\n \n Monday\u2019s earthquake prompted the country\u2019s disaster management agency to issue evacuation orders to more than 180,000 people.\n <\/p>\n \n CNN\u2019s producer on the ground in Tokyo reported feeling the building they were in shake for about seven minutes when the earthquake struck.\n <\/p>\n \n Two people were injured after falling, according to Japan\u2019s Fire and Disaster Management Agency, the AP reported. But no damage to homes had been recorded, chief cabinet secretary Minoru Kihara said Monday evening local time, noting the situation was still being assessed. Kihara added that there were 200 power outages across the impacted areas and authorities were working to restore service.\n <\/p>\n \n The Japan Meteorological Agency initially issued a three-meter tsunami warning for the Iwate prefecture and parts of Hokkaido and Aomori \u2013 later downgraded to an advisory. It also issued an advisory in other areas of northeastern Japan, estimating a tsunami of up to one meter (3.3 feet).\n <\/p>\n \n Observations of tsunami waves were we\ufeffll below the warning level that was issued. One 0.8-meter (2.6-foot) tsunami struck Kuji Port in Iwate Prefecture, according to data from the meteorological agencies. Another 0.4-meter (1.3-foot) tsunami hit Miyako Port in Iwate Prefecture.\n <\/p>\n \n The US Tsunami Warning System reported that the magnitude of the earthquake off the east coast of Honshu, Japan, was 7.4. The tsunami threat was issued at 8:52 UTC (4:52 a.m. ET). Japan\u2019s national agency later revised its figure up to 7.7 magnitude, although it\u2019s unclear why there is a discrepancy in the numbers.\n <\/p>\n
