2024-07-14 18:03:38 UTC (2024-07-14) · approx. 3:03 AM UTC+9 local
On July 14, 2024 at 18:03 UTC, a magnitude 4.5 shallow crustal earthquake struck 189 km SSE of Tateyama, Japan, at a depth of 57.2 km and coordinates 33.4418°, 140.7426°. This earthquake was detected by 82 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
