Summary: The Pawnee, Oklahoma earthquake occurred on September 3, 2016 at 12:02 PM UTC time. The USGS reported magnitude is M5.8, and the epicenter was located 15 km northwest of the town of Pawnee, Oklahoma. The GEER reconnaissance team includes members from the University of Texas at Austin, the University of Texas at Arlington, and USGS. The objective of this reconnaissance effort was to collect and document earthquake effects from a small-to-moderate magnitude event that occurred in a region that has recently experienced an increase in seismicity rates. This report documents observations of liquefaction, damage to earthen levees and dams, ground settlement, and nonstructural damage to buildings and bridge abutments. A Google Earth KMZ file with a summary of sites visited, observations made, and key photos is also provided to supplement the report.
