Texas Earthquakes
Pennington and Davis, both of the Institute of Geophysics of the University of Texas at Austin.Texas. reported that Texas has experienced more than 100 earthquakes of magnitude 3 or greater since 1847. However, because the density of both seismographs and people has been very low in Texas, knowledge of the state’s seismicity is undoubtedly incomplete. The largest known earthquake in Texas occurred on Aug. 16, 1931, near the town of Valentine in Jeff Davis County. The total felt area exceeded one million square kilometers (about 400,000 square miles).
