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

9416774亨耶这项研究将利用拉蒙特-多尔蒂研究船莫里斯·尤因1994年秋季在加利福尼亚州南部水域时的存在，获取穿过北岭震中的折射/广角反射岸上-近海断面。这艘船将在加利福尼亚州南部水域，作为洛杉矶地区地震实验的一部分，该实验已经得到了NSF、SCEC和USGS的资助。R/V Ewing上的10,000英寸调谐气枪阵列将用于在从圣莫尼卡湾到穿过北岭震中地区的西部莫哈韦沙漠的横向山脉褶皱和推覆带上增加一个南北横断面。这项研究的结果将与来自圣费尔南多山谷的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-伊利西亚公园逆冲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.
