9416774 Henyey This study will make use of the presence of the Lamont-Doherty Research Vessel Maurice Ewing when it is in southern California waters in fall 1994 to acquire a refraction/wide angle reflection onshore-offshore transect through the Northridge epicenter. The ship will be in southern California waters as part of the Los Angeles Region Seismic Experiment already funded by the NSF, SCEC and USGS. The 10,000 in tuned air gun array on the R/V Ewing will be used to add a north-south transect over the Transverse Ranges fold and thrust belt form Santa Monica Bay to the western Mojave Desert through the Northridge epicentral region. The results of this study will be combined with reprocessed industry seismic reflection data from the San Fernando Valley to provide information on the subsurface structure of the Santa Monica Mountain-Elysian Park thrust ramp and the Northridge earthquake fault system as will as the San Fernando Basin and its underlying crust.

小行星9416774 这项研究将利用Lamont-Doherty研究船Maurice Ewing 1994年秋季在南加州沃茨时的存在，以获取通过北岭震中的折射/广角反射陆上-海上断面。 该船将在加州南部沃茨作为洛杉矶地区地震实验的一部分，已经由美国国家科学基金会，SCEC和美国地质勘探局资助。 R/V Ewing上的10，000英寸调谐气枪阵列将用于在横贯山脉褶皱和逆冲带上增加一个南北向断面，从圣莫尼卡湾到西部莫哈韦沙漠，穿过北岭震中地区。 这项研究的结果将与圣费尔南多谷再处理的工业地震反射数据相结合，以提供关于圣莫尼卡山-伊利森公园冲断斜坡和北岭地震断层系统的地下结构以及圣费尔南多盆地及其下伏地壳的信息。
