M5.1 Earthquake 57 km SSE of Hiroo, Japan — June 3, 2025
2025-06-03 13:18:28 UTC (2025-06-03) · approx. 11:18 PM UTC+10 local
On June 3, 2025 at 13:18 UTC, a magnitude 5.1 shallow crustal earthquake struck 57 km SSE of Hiroo, Japan, at a depth of 42.8 km and coordinates 41.7865°, 143.4834°. This earthquake was detected by 192 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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 5.1 earthquakes can continue for days to weeks 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 5.1 event is significantly smaller than that historical record.
