Seismic Monitoring Program
OGS Seismic Station
The Oklahoma Geological Survey's Seismic Monitoring Program was established to document and compile information on Oklahoma earthquakes, examine these occurrences, and through extensive research, gain a better understanding of earthquake processes within the state of Oklahoma. Data and discoveries from this research are available to the public on this website.
Data collection and archiving occurs in the main OGS offices at the University of Oklahoma in Norman, Oklahoma. This data is transmitted in realtime from all permanent stations and the majority of temporary stations, some of which are cooperated by the OGS, private research undertakings, the Incorporated Research Institution for Seismology (IRIS) and the United States Geological Survey (USGS). A few additional temporary stations do not transmit data in real-time, but must have data collected periodically. Most stations are continuous-recording stations, meaning they record all the time (whether there is ground motion or not), whereas some stations are accelerometers, recording only when triggered by movement. The map above depicts stations used most often for analysis.
