Felt by 41 people across nearby locations.
On June 3, 2020 at 20:31 UTC, a magnitude 4.9 shallow crustal earthquake struck 8 km E of Funaishikawa, Japan, at a depth of 59.6 km and coordinates 36.4761°, 140.6590°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
