Meers Fault is a fault in Oklahoma that extends from Kiowa County to Comanche County. It is marked by a long conspicuous fault scarp but the fault extends beyond the ends of this scarp. The Meers fault is part of a group of faults that lie between the Anadarko Basin and the Wichita Mountains. While the fault was active during the Permian-Cambrian, movement possibly accompanied by earthquakes took place during the Holocene and formed the fault scarp, with one earthquake occurring less than 2,000 years ago. There is currently no seismicity on the fault but it is considered an earthquake hazard. Appearance The Meers Fault runs along the northern side of Meers Valley through Comanche County and Kiowa County and close to Caddo County in an east-southeast to north-northwest direction. Towns close to the fault are Cooperton, Meers, Apache, Fort Sill, Treasure Island and Elgin; Oklahoma State Highway 19, Oklahoma State Highway 115, Oklahoma State Highway 58 and U.S. Route 281 cross the fault and Oklahoma State Highway 44 might do so as well. The fault scarp is located on private land; the southeastern part runs through farmland and the northwestern part runs through hilly terrain. The Meers fault is a reverse fault (at first it was interpreted to be a normal fault) with a straight path despite a variable topography; it probably does take the form of a broad dislocation rather than of a plane and its expression varies depending on the substrate rock. Underground, the fault may be over long. It dips first northeastward but deeper it becomes either vertical or down-to-the-southwest, but certainly steep at depth. One interpretation is that the Meers fault is a "back-thrust" that dips northwards. Unlike many other faults, there is no evidence of segmentation in the Meers fault. A conspicuous high and – long fault scarp just north of the Wichita Mountains is noticeable on Google Earth; it has formed on the Holocene part of the fault and continues southeastwards in the form of more subtle scarps although it may not exactly coincide with the path of the fault. Because the scarp is not present along the entire length of the fault, it is subdivided in a southeastern section in Comanche County and a northwestern section in Kiowa County, with only the southeastern section featuring a scarp. The scarp marks the Holocene section of the fault. The Meers fault is the only
