A Seismic Refraction/Wide Angle Relfection Transect Through the Northridge Epicenter

9416774 Henyey 这项研究将利用 1994 年秋季 Lamont-Doherty 研究船 Maurice Ewing 位于加利福尼亚州南部水域时的情况，获取穿过北岭震中的折射/广角反射陆上 - 海上横断面。 该船将在南加州水域航行，作为洛杉矶地区地震实验的一部分，该实验已由 NSF、SCEC 和 USGS 资助。 R/V Ewing 上的 10,000 个调谐气枪阵列将用于在横向山脉褶皱和冲断带上增加一条南北横断面，从圣莫尼卡湾到莫哈韦沙漠西部，穿过北岭震中地区。 这项研究的结果将与圣费尔南多谷经过重新处理的工业地震反射数据相结合，提供有关圣莫尼卡山-乐土公园冲断坡道和北岭地震断层系统以及圣费尔南多盆地及其下伏地壳的地下结构的信息。

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.
