Strong Earthquake Shakes Northern Japan as Tsunami Advisory Lifted

A powerful earthquake struck off the northern coast of Japan on Sunday evening, prompting temporary tsunami advisories along coastal areas, according to the Japan Meteorological Agency.

The quake, which the agency measured at magnitude 6.9, occurred at a depth of about 20 kilometers off the coast of Iwate Prefecture at 5:03 p.m. local time. The tremor was followed by several aftershocks and was felt across parts of northern Honshu and Hokkaido.

There were no immediate reports of injuries, major structural damage, or irregularities at nearby nuclear power facilities.

Authorities initially issued tsunami advisories warning that waves could reach up to 1 meter in height. The advisory was later downgraded after tsunami waves measuring between 10 and 20 centimeters were recorded in Ofunato, Miyako, Ominato, Kamaishi and Kuji. Residents were urged to stay away from coastal areas while the advisories remained in effect.

The tsunami advisory was lifted approximately three hours later. However, officials cautioned that the region could experience further significant aftershocks over the next several days, particularly within the next 48 to 72 hours.

Additional tremors were recorded across Iwate Prefecture and on the northern island of Hokkaido as monitoring and assessment continued. Authorities said they remain on alert and advised residents to follow local safety instructions.
