A strong earthquake occurred off the coast of Northeast Japan this afternoon, triggering tsunami warnings. The earthquake's magnitude has been revised to 7.5. Tsunami alerts have been issued for the Pacific coasts of Hokkaido, Aomori Prefecture, and Iwate Prefecture, with predictions of tsunami waves up to 3 meters arriving rapidly.
According to the Japan Meteorological Agency, as of 5:41 PM, observed tsunami heights included 0.8 meters at Kuji Port in Iwate Prefecture at 5:34 PM and 0.4 meters at Miyako, Iwate Prefecture, at 5:22 PM.
Furthermore, in some areas, the actual tsunami height may exceed the values measured by tide gauges.
The Japan Meteorological Agency stated that it is conducting further analysis of the earthquake's magnitude and epicenter to determine if it meets the criteria for issuing a "Hokkaido/Sanriku-oki Aftershock Warning," warning of the possibility of subsequent large-scale earthquakes.
The Japanese government has set up a liaison office in the Prime Minister's office crisis management center. Prime Minister Sanae Takaichi, in a statement, urged residents in areas with tsunami warnings to immediately evacuate to higher ground or tall buildings to ensure their safety.
In terms of transportation, JR East announced that operations on the Tohoku Shinkansen line between Tokyo and Shin-Aomori have been suspended. Regarding electricity, Tohoku Electric Power reported that no abnormalities have been found at the Higashidori Nuclear Power Plant in Aomori Prefecture and the Onagawa Nuclear Power Plant in Miyagi Prefecture.
Authorities remind the public that tsunamis may continue to intensify after the first wave, and the highest waves may appear several hours later. Coastal residents are urged not to let their guard down. (Editor: Chen Cheng-kung) 1150420
