Seismic Activity in Oklahoma City: Frequency and Magnitude

The city of Oklahoma City, Oklahoma, has experienced a significant increase in seismic activity over the past decade, largely attributed to the injection of wastewater from oil and gas operations.

Overview of Seismic Activity

Since 2010, the state of Oklahoma has recorded thousands of earthquakes, many of which have been felt in and around Oklahoma City. Specifically, the city has seen dozens of noticeable earthquakes each year, particularly during the early 2010s when the activity peaked. On average, the state has witnessed around 1000 earthquakes of magnitude 2.5 or greater annually, with a smaller percentage being felt in urban areas like Oklahoma City. In recent years, the frequency has varied but it has been common to feel several earthquakes each year in the city.

Frequency of Earthquakes

For a more precise number, you would need to check the latest data from the U.S. Geological Survey (USGS) or the Oklahoma Geological Survey, as they maintain updated records of seismic activity. It's worth noting that some quakes have occurred several times a day within a 50-mile radius of Oklahoma City, but most of these cannot be detected without a seismograph.

Magnitude of Earthquakes

Earthquakes in Oklahoma City range in magnitude. While some quakes occur several times a day, the majority cannot be felt without the use of seismograph equipment. Major earthquakes with a magnitude of 4 or greater are rare but do happen occasionally.

Resources and Data

The U.S. Geological Survey (USGS) website (USGS.gov) provides worldwide statistics and maps of seismic activity. This resource is invaluable for understanding the global context of seismic activity and for detailed analysis of specific events.
