Felt by 18 people across nearby locations.
On June 27, 2023 at 23:46 UTC, a magnitude 3.3 shallow crustal earthquake struck 14 km N of Snyder, Texas, at a depth of 4.1 km and coordinates 32.8427°, -100.9467°. This earthquake was detected by 25 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 175, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Texas, a region characterized by a mix of natural intraplate seismicity and induced events in the Permian Basin linked to wastewater disposal. View all earthquakes in Texas.
