Felt by 12 people across nearby locations.
On September 30, 2024 at 17:30 UTC, a magnitude 2.5 shallow crustal earthquake struck 4 km E of Cole, Oklahoma, at a depth of 5.3 km and coordinates 35.1015°, -97.5230°. This earthquake was detected by 97 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 98, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 71.4 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 30 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.
