M7.0 Earthquake in the Bonin Islands, Japan region — October 24, 2026
2026-10-24 02:09:00 UTC (1 day ago) · approx. 11:09 AM UTC+9 local
On October 24, 2026 at 02:09 UTC, a magnitude 7.0 deep-focus earthquake struck in the Bonin Islands, Japan region, at a depth of 473.0 km and coordinates 28.0000°, 139.9000°. This earthquake was detected by 10 seismic stations and was assigned a USGS significance rating of 754, making it a moderate-impact event.
Physical scale: An earthquake of magnitude 7.0 releases seismic energy equivalent to roughly 477 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 41 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Japan, a region characterized by the intersection of four tectonic plates — Pacific, Philippine Sea, Eurasian, and North American — creating multiple subduction zones. The nearest mapped fault system is the Japan Trench. View all earthquakes in Japan.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 7.0 earthquakes can continue for months to years and gradually diminish over time.
Has Japan had earthquakes this big before?
The largest recorded earthquake in Japan was the M9.1 Tohoku earthquake of March 11, 2011. Today's magnitude 7.0 event is significantly smaller than that historical record.
