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. ***

9416384 Kelson这项研究将绘制与北北圣费尔南多谷（North San Fernando Valley）相关的第四纪晚期表面变形的位置和模式。将对与地震相关的地貌特征进行评估，以查看它们是否可以用于描述公共规划地图上潜在的地震危险区域。可能与1930年的航空照片集合（在该地区进行城市化之前拍摄的特殊收集）和老式的地形图，将绘制潜在相关的地貌特征的分布。纵向流谱和通道模式分析将有助于识别地震相关的抗障碍变形。 1：24,000尺度的地图将在燕麦山，范努伊斯，圣费尔南多和Canoga Park四边形的燕麦山发生后期变形。这项研究的结果将产生有关盲推断层和地貌特征关联的信息，并将有助于制定方法以描述有关地质和计划地图的此类信息。 ***
