9316871 Henyey This research is to reduce and analyze seismic reflection data from the Mojave Desert and San Bernardino Mountains in Southern California. The seismic data were collected using three-channel portable recorders to detect seismic waves generated by aftershocks of the 1992 M=7.5 Landers earthquake. The goal of the experiment is to study the depth of the crust in the region by comparing the travel time differences between waves traveling through the crust and those reflected from the base of the crust. Crustal depths are important to models of the shape of the San Andreas fault surface in the southern California region. This research is a component of the National Earthquake Hazard Reduction Program. ***

小行星9316871 本研究是要减少和分析来自莫哈韦沙漠和圣贝纳迪诺山在南加州的地震反射数据。 地震数据收集使用三通道便携式记录仪，以检测1992年M=7.5兰德斯地震的余震产生的地震波。 实验的目的是通过比较穿过地壳的波和从地壳底部反射的波之间的旅行时间差来研究该地区地壳的深度。 地壳深度对加州南部地区圣安德烈亚斯断层表面形状的模型很重要。 这项研究是国家地震减灾计划的一个组成部分。 ***
