Felt by 337 people across surrounding communities.
On February 23, 2022 at 23:25 UTC, a magnitude 2.7 shallow crustal earthquake struck 4 km NE of Jackson, Wyoming, at a depth of 5.3 km and coordinates 43.5066°, -110.7286°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Wyoming, a region characterized by the Yellowstone volcanic system and Teton Fault, where a mantle plume drives volcanic seismicity and crustal extension. The nearest mapped fault system is the Teton Fault. View all earthquakes in Wyoming.
