An M5.7 earthquake was recorded at 04:52 UTC on November 9, 2026, about 106 km (66 miles) east-northeast of Hasaki, Japan. The event occurred at a depth of 24.2 km (15 miles).
The earthquake’s epicenter was located offshore, near 36.2°N, 141.8°E, in the Pacific Ocean east of Honshu. The nearest coastal city is Hasaki, situated more than 100 km (62 miles) to the west of the event location.
Given the offshore setting near the crowded Pacific coast of Honshu, nearby infrastructure may include shipping routes, regional ports, and potential energy facilities typical for coastal Japan. The affected maritime area may also intersect with international sea traffic lanes.
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 earthquake reached an estimated maximum intensity of IV, with 3 felt reports submitted. The significance index is 501 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
Japan is situated along the Pacific Ring of Fire, characterized by complex subduction zones and transform faults where the Pacific Plate interacts with the North American and Eurasian Plates, making the region susceptible to frequent seismic activity.
