2024-05-08 19:34:44 UTC (2024-05-08) · approx. 4:34 AM UTC+9 local
On May 8, 2024 at 19:34 UTC, a magnitude 4.5 intermediate depth earthquake struck 8 km NNE of Takedamachi, Japan, at a depth of 104.7 km and coordinates 33.0408°, 131.4384°. This earthquake was detected by 81 seismic stations with excellent 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.
