A 7.7 magnitude earthquake off the Japanese coast has triggered a tsunami warning, prompting mass evacuations. The tremor, striking the country’s northeastern coast, has raised concerns of a potential tsunami reaching up to three meters in height in Iwate prefecture and parts of Hokkaido. Authorities have activated disaster prevention measures in 182 areas spanning cities, towns, and villages across several prefectures. The Japan Meteorological Agency has advised residents to prepare emergency kits and secure their surroundings in anticipation of potential evacuations. The likelihood of another significant earthquake remains high, with a 1% chance of a major quake occurring near Hokkaido and Sanriku, ten times higher than normal conditions. Evacuation orders impacting over 156,000 people have been issued in response to the tsunami warnings. Despite the downgrade in warnings, coastal areas from Hokkaido to Fukushima Prefecture are under tsunami advisories, urging individuals to stay away from vulnerable areas. The earthquake’s epicenter, located off the coast of Sanriku, has heightened concerns about the potential for a mega-quake, prompting officials to emphasize preparedness and safety measures for the affected regions.
