Description
We have completed initial paleoseismologic investigations to evaluate the recency and size of paleoearthquakes and long-term slip rates on the Hurricane fault in southern Utah and northern Arizona (SUNA). The Hurricane fault is a long, west-dipping normal fault with substantial late Cenozoic displacement within the structural and seismic transition between the Colorado Plateau and the Basin and Range province. Previous reconnaissance studies of the fault in northern Arizona and southern Utah had documented evidence of late Quaternary activity. Because of its great length, the Hurricane fault almost certainly ruptures in segments, and abundant geometric and structural characteristics suggestive of fault segmentation exist along its trace. Our efforts have focused on a systematic, detailed reconnaissance of the fault from the Utah-Arizona border north to Cedar City and a detailed investigation of 20 km of the fault from the border southward into Arizona. In addition, we conducted detailed reconnaissance investigations of the fault in Whitmore Canyon north of the Colorado River. (137 pages)
