Felt by 141 people across surrounding communities.
On May 19, 2026 at 06:47 UTC, a magnitude 3.5 shallow crustal earthquake struck 2 km ESE of Johnson, Oklahoma, at a depth of 17.5 km and coordinates 35.3972°, -96.8158°. This earthquake was detected by 97 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 242, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 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.
