A magnitude 6.7 earthquake struck off the coast of Aomori Prefecture in northeastern Japan on Friday, December 12, 2025, at 11:44 am local time, prompting a tsunami advisory from the Japan Meteorological Agency (JMA). The quake's depth was approximately 20km. No immediate abnormalities were reported at nuclear facilities in the region. This event follows a magnitude 7.5 earthquake earlier in the week that caused damage and injuries in the same area, leading the JMA to issue a special advisory warning of potential aftershocks. The region is also sensitive to earthquake risks due to the devastating 2011 earthquake and tsunami.
