CGS Landslide Zones

This is a digital Seismic Hazard Zone Map presenting areas where liquefaction and landslides may occur during a strong earthquake. Three types of geological hazards, referred to as seismic hazard zones, may be featured on the map: 1) liquefaction, 2) earthquake-induced landslides, and 3) overlapping liquefaction and earthquake-induced landslides. In addition, a fourth feature may be included representing areas not evaluated for liquefaction or earthquake-induced landslides. Developers of properties falling within any of the three zones may be required to investigate the potential hazard and mitigate its threat during the local permitting process.本数据集为数字地震灾害带地图（digital Seismic Hazard Zone Map），展示了强震期间可能发生液化（liquefaction）与滑坡的区域。该地图标注了三类被归为地震灾害带的地质灾害类型：1）液化，2）地震诱发滑坡（earthquake-induced landslides），3）液化与地震诱发滑坡重叠区。此外，地图还可包含第四类区域，即未针对液化或地震诱发滑坡开展危险性评估的区域。若不动产开发项目位于上述三类灾害带范围内，开发方在当地办理项目许可手续期间，可能需开展潜在灾害调查并采取措施减缓灾害威胁。
