资源简介:
This map shows the relative likelihood of deep landsliding based on regional estimates of rock strength and steepness of slopes. On the most basic level, weak rocks and steep slopes are more likely to generate landslides. This shows the distribution of one very important component of landslide hazard. It is intended to provide infrastructure owners, emergency planners and the public with a general overview of where landslides are more likely. The map does not include information on landslide triggering events, such as rainstorms or earthquake shaking, nor does it address susceptibility to shallow landslides such as debris flows. This map is not appropriate for evaluation of landslide potential at any specific site.

If gridcode is 8,9,10 than area is High Susceptibility for landslides
本图展示了基于区域岩石强度和坡度陡峭度的估计,对深层滑坡相对发生可能性的分布。在最基本层面上,岩石强度较弱且坡度陡峭的区域更易发生滑坡。该图展示了滑坡风险一个至关重要的组成部分的分布情况。其旨在为基础设施所有者、紧急规划人员及公众提供滑坡易发区域的总体概览。该图未包含滑坡触发事件的信息,例如暴雨或地震震动,亦未涉及浅层滑坡(如泥石流)的易损性。本图不适用于评估特定地点的滑坡潜力。
可视化说明:
若网格代码为8、9或10,则该区域对滑坡具有高敏感性。
