详细而准确的滑坡调查是地震滑坡危险性分析的重要组成部分。理想的清单应涵盖受地震影响的整个地区，并包括所有可能检测到的长度为1-5米的滑坡。滑坡还必须准确定位，并绘制成描绘其真实形状的多边形。这样绘制的滑坡分布图可用于进行地震滑坡危险性分析和其他定量分析。地震引发的山体滑坡的详细清单地图始于20世纪60年代初，当时使用的是航空摄影。近年来，由于技术的进步，人们可以获得分辨率足够高的卫星图像，以查明和绘制除最小的地震事件以外的所有山体滑坡。有了这种查看地球仪任何区域的能力，我们可以获取任何引发大量山体滑坡的地震的图像。然而，随着高分辨率卫星图像的出现，一个普遍的问题是对滑坡的全分布覆盖不完全，这沿着出现。由爱思唯尔公司出版
A detailed and accurate landslide inventory is an essential part of seismic landslide hazard analysis. An ideal inventory would cover the entire area affected by an earthquake and include all of the landslides that are possible to detect down to sizes of 1-5 m in length. The landslides must also be located accurately and mapped as polygons depicting their true shapes. Such mapped landslide distributions can then be used to perform seismic landslide hazard analysis and other quantitative analyses. Detailed inventory maps of landslide triggered by earthquakes began in the early 1960s with the use of aerial photography. In recent years, advances in technology have resulted in the accessibility of satellite imagery with sufficiently high resolution to identify and map all but the smallest of landslides triggered by a seismic event. With this ability to view any area of the globe, we can acquire imagery for any earthquake that triggers significant numbers of landslides. However, a common problem of incomplete coverage of the full distributions of landslides has emerged along with the advent of high resolution satellite imagery. Published by Elsevier B.V.
