On February 12, 2024 at 11:19 UTC, a magnitude 6.1 intermediate depth earthquake struck in the Volcano Islands, Japan region, at a depth of 236.0 km and coordinates 22.0086°, 142.7919°.0 The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 168 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 573, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.1 releases seismic energy equivalent to roughly 21 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 9.7 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.
