A powerful magnitude-7.4 earthquake rocked northeastern Japan's Pacific coast today, triggering immediate tsunami warnings for coastal communities. The tremor occurred at 4:53 p.m. local time near Honshu's eastern shoreline, with its epicenter located just 10 kilometers below the seabed, according to the China Earthquake Networks Center.
The Japan Meteorological Agency issued urgent evacuation orders for Iwate, Aomori, and Hokkaido prefectures, forecasting tsunami waves potentially reaching 3 meters. Coastal residents reported feeling strong shaking lasting nearly a minute, with preliminary reports indicating power outages and disrupted transportation services.
Emergency response teams have been mobilized across affected regions, while Tokyo Electric Power Company confirms it is monitoring nuclear facilities in the area for any abnormalities. This seismic event marks the strongest earthquake recorded in the region since the 2021 Fukushima aftershocks.
As night falls on April 20, 2026, authorities urge residents to avoid coastal areas and follow evacuation protocols until the tsunami warning is lifted. International travelers are advised to monitor official advisories through their embassies and local media.
