M5.3 Earthquake 126 km SSE of Itoman, Japan — July 12, 2024
2024-07-12 23:18:47 UTC (2024-07-12) · approx. 8:18 AM UTC+9 local
On July 12, 2024 at 23:18 UTC, a magnitude 5.3 shallow crustal earthquake struck 126 km SSE of Itoman, Japan, at a depth of 10.0 km and coordinates 25.0886°, 128.1823°. This earthquake was detected by 289 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
