Earthquakes in Oklahoma

Latest earthquakes in Oklahoma, United States: 1 in the last 24 hours, 78 in the last 30 days. Updated Nov 10, 2026 00:18 UTC.

Oklahoma has an unusual earthquake history. For decades the state had only a couple of magnitude 3 or larger earthquakes per year. Starting around 2009, the rate shot up, and the USGS catalog lists close to 900 magnitude 3 and larger events in the region in 2015 alone. USGS and Oklahoma Geological Survey scientists linked the increase to the underground injection of wastewater from oil and gas production, which raised the pressure on faults that were already stressed. The strongest earthquake was the magnitude 5.8 Pawnee earthquake of September 3, 2016, felt in many states; the magnitude 5.7 Prague earthquake of November 6, 2011 was almost as large. After regulators ordered cuts in injection volumes, the numbers dropped sharply, though the state still has more small earthquakes than before 2009. Oklahoma is a textbook case of induced seismicity, where human activity changes the earthquake hazard. The list below shows the most recent 30 days.
