7.6-Magnitude Quake Triggers Tsunami Alert in Northern Japan
A powerful undersea earthquake struck off the northern coast of Japan late on December 8. The tremor, measured at magnitude 7.6, hit offshore near Aomori Prefecture and was felt across several regions in northern Honshu and parts of Hokkaido. The quake shook buildings, rattled windows and caused temporary power disruptions in some localities.
Tsunami warning issued
Authorities immediately issued tsunami alerts for coastal areas, warning that waves could reach up to three metres. People living near the shorelines were urged to evacuate to higher ground. Actual tsunami waves that reached coastal areas were significantly smaller, recorded at under one metre in most locations. Emergency sirens and public broadcast systems were used throughout the night to direct people to shelters.
Injuries and local impact
More than 20 people were reported injured, largely due to falling objects, broken glass and accidents during evacuation. Some buildings and hotels along the coast reported minor structural damage, although no major collapse was reported. Transport systems remained functional, though several train services were suspended temporarily as safety checks were carried out.
Nuclear plants safe, alerts lifted
Officials confirmed that nuclear power facilities in the region remained safe, with no abnormalities detected. By early morning, tsunami warnings were lifted as no widespread flooding or coastal destruction occurred. Residents were still advised to remain cautious due to the possibility of aftershocks.
Preparedness and vigilance
Japan’s disaster response system was fully activated, with local governments, police and fire services coordinating evacuation and rescue operations. The quick mobilisation of emergency teams and public communication helped prevent loss of life. Experts noted that the region, known for frequent seismic activity, must remain prepared at all times as even moderate tsunami waves can be dangerous in low-lying areas.
