A magnitude 6.7 earthquake struck off the eastern coast of Aomori Prefecture in Japan, prompting a tsunami warning for Aomori, Iwate, Miyagi, and parts of Hokkaido.
Authorities warned of possible waves up to 1 meter and urged residents to stay away from coastal areas. The quake comes days after a stronger 7.5 tremor hit the same region, raising concerns over further seismic activity.
