Felt by 38 people across nearby locations.
On February 13, 2021 at 22:01 UTC, a magnitude 2.4 shallow crustal earthquake struck 12 km NW of Edmond, Oklahoma, at a depth of 6.6 km and coordinates 35.7405°, -97.5563°. This earthquake was detected by 97 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 106, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 62.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 28 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Oklahoma, a region characterized by induced seismicity from high-volume wastewater injection into the Arbuckle Group formation, which reactivates ancient basement faults. View all earthquakes in Oklahoma.
