CGS Alquist Priolo Fault Zones

This data set contains the Alquist-Priolo Earthquake Fault Zones as shown on the Official Alquist-Priolo Earthquake Fault Zones Maps. The dataset is comprised of polygons that form regulatory zone boundaries (Alquist-Priolo Earthquake Fault Zones). These features delineate areas where surface fault rupture previously has occurred, or where local topographic, geological, and geotechnical conditions indicate a potential for permanent ground displacements such that mitigation by avoidance as stated in Public Resources Code Section 2621.5 would be required.本数据集收录了官方阿尔奎斯特-普里奥洛地震断层带（Alquist-Priolo Earthquake Fault Zones）地图中载明的阿尔奎斯特-普里奥洛地震断层带。该数据集由构成监管区域边界（阿尔奎斯特-普里奥洛地震断层带）的多边形要素组成，这些要素划定了曾发生过地表断层破裂，或局部地形、地质及岩土工程条件显示存在永久性地面位移风险的区域，此类区域需按照《公共资源法典》第2621.5条的规定采取避让减灾措施。
