“Examining Fault Scarps in the Yuha Desert, to Determine if They Were Caused by the 1892 Laguna Salada Earthquake” Author: Peter G. Hopper The 1892 Laguna Salada earthquake was an oblique slip, dextral earthquake that occurred at 23:20 Pacific Standard Time on February 23. It was estimated to be a 7.2 on the magnetic moment scale, and a perceived maximum intensity of VII (Severe). This fault presents a roughly 23km area of surface faulting with vertical displacement as high as 4m. To further examine the extent of this earthquake, a pair of suspected fault scarps were chosen in the Yuha Desert. These scarps were chosen because on an aerial view they could be seen crossing Quaternary Fill, and thus were suspected to be very recent. They were analyzed by first profiling the scarps, then calculating the weathering coefficient, and finally, comparing data to known examples of surface ruptures of the 1892 earthquake. It was ascertained that both scarps were part of an older slip, and not as a result of the 1892 earthquake.
