These maps should not be considered as zoning guides, nor be used for risk assessment. Because of the sheer number of faults in southern California, this is not an exhaustive collection. Most, if not all, of this material has a certain level of uncertainty to it. Our understanding of faults is constantly expanding, and new faults and better data may be added to these maps as our knowledge about these structures advances. Also , to use these imagemaps your browser must be compatible with client-side imagemaps.
