M4.8 Earthquake 56 km SSE of Makubetsu, Japan — August 10, 2022
2022-08-10 15:35:18 UTC (2022-08-10) · approx. 12:35 AM UTC+9 local
On August 10, 2022 at 15:35 UTC, a magnitude 4.8 shallow crustal earthquake struck 56 km SSE of Makubetsu, Japan, at a depth of 10.0 km and coordinates 44.8780°, 142.0110°. This earthquake was detected by 144 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
