Assessment of Late Quaternary Surficial Deformation, San Fernando Valley

9416384凯尔森这项研究将绘制与圣费尔南多河谷北部埋藏的潜在震源有关的第四纪晚期地表形变的位置和模式。将对与地震有关的地貌特征进行评估，看看它们是否可以用来在公共规划地图上划定潜在的地震危险区域。潜在与断层有关的地貌特征的分布将使用1930年S航拍的特殊集合(在该地区城市化之前拍摄)和古老的地形图来绘制。纵向河流剖面和河道形态分析将有助于识别与地震有关的背斜变形。将制作燕麦山、Van Nuys、San Fernando和Canoga公园四合院内晚第四纪变形的1：24,000比例尺地图。这项研究的结果将提供有关隐伏逆冲断层与地貌特征的联系的信息，并将有助于设计在地质和规划图上描述此类信息的方法。***

9416384 Kelson This study will map the locations and patterns of late Quaternary surficial deformation related to buried, potentially seismogenic sources in the northern San Fernando Valley. An assessment will be made of earthquake-related geomorphic features to see if they can be used to delineate areas of potential seismic hazard on public planning maps. The distribution of potentially fault- related geomorphic features will be mapped using a special collection of 1930's aerial photographs, taken prior to urbanization in the area, and vintage topographic maps. Longitudinal stream profiles and channel pattern analyses will assist in recognition of earthquake- related anticlinal deformation. 1:24,000-scale maps will be produced of late Quaternary deformation within the Oat Mountain, Van Nuys, San Fernando and Canoga Park quadrangles. The results of this study will yield information on the association of blind thrust faults and geomorphic features, and will assist in devising methods to depict such information on geologic and planning maps. ***
