M4.7 Earthquake 169 km E of Yamada, Japan — June 12, 2020
2020-06-12 19:16:24 UTC (2020-06-12) · approx. 5:16 AM UTC+10 local
On June 12, 2020 at 19:16 UTC, a magnitude 4.7 shallow crustal earthquake struck 169 km E of Yamada, Japan, at a depth of 53.6 km and coordinates 39.2774°, 143.8977°.
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.
