Desk Correspondent , Tokyo - A powerful magnitude 7.5 earthquake struck off Japan's northeastern coast on April 20, 2026, at approximately 4:52 PM JST, with its epicenter located near Iwate prefecture in the Pacific Ocean, sending intense tremors across multiple regions and prompting urgent tsunami warnings from the Japan Meteorological Agency (JMA). Prime Minister Sanae Takaichi activated national emergency protocols as an initial tsunami wave measuring 40-70 cm slammed into Miyako port in Iwate, while authorities issued stark alerts for a potential second, much larger wave up to 3 meters (10 feet) high threatening the coasts of Iwate, Aomori, Miyagi, and parts of Hokkaido, urging over 100,000 residents to evacuate to higher ground immediately amid fears of widespread coastal flooding.

The quake's prolonged shaking, lasting over 30 seconds even in Tokyo more than 400 km distant, toppled unsecured objects, injured dozens primarily from falls and flying debris, and triggered localized power outages in coastal communities, though no collapsed buildings or fires have been confirmed yet, bullet trains halted nationwide, airports suspended flights, and nuclear facilities like Onagawa reported no radiation leaks but remain on high alert. Rescue teams, Self Defense Forces, and JMA observers surged into action, with live broadcasts capturing anxious crowds fleeing low lying areas as sirens wailed, while aftershocks some exceeding magnitude 5 continued to rattle nerves in the seismically active Ring of Fire zone.

While initial waves caused no major inundation, experts caution that the forecasted larger tsunami could mirror devastating past events like 2011's Tohoku disaster, compounded by Japan's ongoing mega quake preparedness drills, coastal defenses held firm so far, but prolonged disruptions to shipping, fishing, and power grids loom if the alert persists. As of now, the situation remains fluid with evacuations ongoing authorities plead for compliance to avert casualties, eyeing a delicate balance between rapid response and the unpredictable fury of nature in one of the world's most quake prone nations.
