Özet

Studying previously published and other publicly available geologic evidence of Quaternary faulting in the midcontinent United States, Wheeler and Crone [Eng. Geol. 62 (2001) 5 1] judged that the 30-km northwest extension of the Meers Fault in southwestern Oklahoma suggested by Cetin [Cetin, H., 1992, The northwest extension of the Meers fault in southwestern Oklahoma. Proc. 28th Symp. Eng, Geology and Geotechnical Eng., University of Idaho, Boise, ID, pp, 43-58,] is not of Quaternary age, and claimed that Holocene surface rupture has been limited to the previously reported 26-37-km section of the fault to the southeast. Surface rupture length is one of the most commonly used parameters to infer magnitudes of paleoearthquakes and, thus, potential future earthquakes, in seismic hazard studies. As a result, underestimating fault dimensions may lead to serious errors in earthquake hazard evaluation.
