On June 27, 2024 at 19:27 UTC, a magnitude 4.9 shallow crustal earthquake struck 32 km ESE of Wadomari, Japan, at a depth of 37.3 km and coordinates 27.2326°, 128.9261°. This earthquake was detected by 69 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 371, placing it among routine seismic activity.
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.
