Earthquakes

How many earthquakes does Oklahoma have each year?

Oklahoma had 883 earthquakes of magnitude 3 or more in 2015, after averaging about 1 a year from 1973 to 2008; it had 6 in 2025. USGS scientists link the surge to wastewater from oil and gas production pumped deep underground, and the count fell after Oklahoma limited that injection from 2015.
