M4.7 Earthquake 97 km SE of Wadomari, Japan — February 13, 2024
2024-02-13 10:18:40 UTC (2024-02-13) · approx. 7:18 PM UTC+9 local
On February 13, 2024 at 10:18 UTC, a magnitude 4.7 shallow crustal earthquake struck 97 km SE of Wadomari, Japan, at a depth of 10.0 km and coordinates 26.8405°, 129.4267°. This earthquake was detected by 48 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
