| Abstract: | Holocene reactivation of the aseismic Meers fault in southwestern Oklahoma illustrates the limitation of using the historical seismic record for identifying hazardous faults in the central United States. The 26- to 37-km-long fault sarp is one of the few known scarps recording Holocene movement in the central and eastern United States. Two documented late Holocene slip events, each with about 2.5 m of net slip and estimated Ms ranging from 6 3/4 to 7 1/4 , identify the Meers fault as a potentially hazardous fault. In the present-day strike-slip regional stress field, the observed up-to-the-north Holocene displacement suggests that either the fault continues to dip steeply at depth or the regional stress field is approaching a normal-faulting stress regime. If the former is true, the scarcity of near-vertical faults with similar orientation within the areas of the southern Oklahoma aulacogen implies that few are likely candidates for reactivation. from Author |
