Assessment of Late Quaternary Surficial Deformation, San Fernando Valley

这项研究将绘制出与圣费尔南多谷北部埋藏的潜在发震源有关的晚第四纪地表变形的位置和模式。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图上划定潜在地震危险区。潜在的与断层有关的地貌特征的分布将使用一组特殊的20世纪30年代的航空照片和古地形图来绘制，这些照片是在该地区城市化之前拍摄的。纵向河流剖面和河道模式分析将有助于识别与地震有关的背斜变形。将制作1:24 000比例尺的Oat山、Van Nuys、San Fernando和Canoga Park四合院的晚第四纪变形地图。这项研究的结果将产生关于盲目逆冲断层和地貌特征之间关系的信息，并将有助于设计在地质图和规划图上描绘这些信息的方法。＊＊＊

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. ***
