The world remains on edge as a powerful 7.4 magnitude earthquake struck the northern coast of Japan on Monday, April 20, 2026. The seismic event, centered in the Pacific waters off the coast of the Iwate Prefecture, immediately triggered urgent warnings from the Japan Meteorological Agency (JMA).

The intensity of the quake was felt far beyond the epicenter. In Tokyo, hundreds of kilometers away, residents reported violent shaking that lasted for over a minute, causing high-rise buildings to sway significantly and sparking widespread alarm across the capital.

Following the initial shock, the JMA issued a critical tsunami alert, forecasting waves as high as three metres. The danger was not merely theoretical; officials observed actual tsunami activity shortly after the quake:
