As of 16:07 UTC on Nov. 7, 2026, the U.S. Geological Survey (USGS) said a magnitude 5.5 earthquake struck 74 kilometers northeast of Hasaki, Japan, at 8:07 p.m. local time on Nov. 7, 2026, at a depth of 31.7 kilometers.

USGS's Did You Feel It system had logged 21 reports from people who felt the shaking, and the agency's impact estimate says there is a low likelihood of casualties and damage.

USGS puts about 1,670,000 people in the area of light shaking, MMI IV, and about 413,000 in weak shaking, MMI III. Overall, the agency says, the region's population lives in structures resistant to earthquake shaking, though vulnerable buildings exist, with heavy wood frame and reinforced or confined masonry construction the predominant vulnerable types.
