A 7.5-magnitude earthquake struck off northeastern Japan in the Pacific Ocean at a shallow depth, triggering urgent tsunami warnings and immediate evacuation orders as coastal areas were placed at risk of waves up to three meters (about 10 feet).

Within minutes, officials reported smaller tsunami waves already reaching some northern ports, measuring around 70–80 centimeters. Authorities warned that tsunami waves can arrive in multiple surges and urged residents in Aomori, Miyagi, and Fukushima to move to higher ground and remain in evacuation areas until all alerts are lifted.

The shaking was felt widely, including in Tokyo, where buildings swayed and people experienced strong tremors. Transport was disrupted, with bullet train services suspended in some regions as a safety measure.

Emergency teams, including military units, were deployed as authorities assessed damage to infrastructure and communities. Early checks at nuclear facilities, including Fukushima, reported no abnormalities or radiation changes, easing some immediate concerns while monitoring continues.

Japan, located on the Pacific Ring of Fire, frequently experiences earthquakes, though events of this magnitude remain serious. Officials continue to urge caution, warning that tsunami waves may continue in cycles and that residents should not return to coastal zones too early.
