Shallow M5.5 earthquake hits northeast of Hasaki, Japan

An earthquake of magnitude M5.5 struck 74 km (46 miles) northeast of Hasaki, Japan, at 11:07 UTC on November 7, 2026. The hypocenter was located at a depth of 31.7 km (19.7 miles), with epicentral coordinates at 141.4°E, 36.2°N.

This event occurred in the offshore region northeast of Hasaki on the eastern side of Honshu, placing it near the Pacific coast of Japan. The nearest significant urban centers and coastal towns are situated inland from the epicenter.

Given its proximity to coastal settlements along Japan’s eastern seaboard, the area may have critical infrastructure such as highways, ports, and energy transport facilities supporting regional commerce and local communities.

There is no tsunami threat associated with this earthquake, based on its location and available data.

USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity reached IV (4.054) on the Modified Mercalli scale. Ten felt reports were submitted. The significance index is 468 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

This sector of Japan lies along the Pacific Ring of Fire, where the Pacific Plate subducts beneath the North American Plate, resulting in frequent seismic activity and numerous moderate to large earthquakes.
