Felt by 22 people across nearby locations.
On November 7, 2026 at 11:53 UTC, a magnitude 3.4 shallow crustal earthquake struck 6 km E of Calumet, Oklahoma, at a depth of 5.8 km and coordinates 35.6103°, -98.0430°. This earthquake was detected by 92 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 186, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 129 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.
