摘要

地震次生地质灾害指由地震活动引起的地质灾害。地震次生地质灾害

主要为崩塌、滑坡

其次为塌陷、地裂缝、砂土液化等。地震次生地质灾害增强了地震的破坏效应

加剧了地震灾害的损失程度

给抢险救灾和灾后重建造成很大困难。一般震级大于5级、烈度超过6度的地震可能引发不同程度的地质灾害

震级和烈度越高

次生地质灾害越严重。本文根据中国历史地震次生地质灾害的活动程度及发生条件

以地（市、区、盟）为单元

进行了危险性评价:高度和中度危险区主要分布在中国中部的陕甘宁川渝滇藏地区

形成一个大致北北东向的高危险带

其余大部分地区为轻度危险区。

Abstract

The earthquake secondary geological hazards are referred to those geological hazards due to earthquakes.They can be classified mainly into land collapse and landslide

together with subsidence

ground fissure and sand liquefaction

etc.The destructive effect and damage level of earthquakes could be exacerbated by the secondary geological hazards

which poses great difficulty

in turn

for the rescue and relief work

and the post-disaster reconstruction.Generally

earthquakes with magnitude over 5.0 and intensity beyond Ⅵ would result in geological hazards at certain degrees

the higher the magnitude and the intensity were

the more serious would be the secondary geological hazards.Based on the conditions and serious extents of the earthquake secondary geological hazards in history

the risk levels have been assessed in this paper at prefectural（city

region

union） units: The areas with high and moderate levels of risk are mainly distributed in the region of Shanxi-Gansu-Ningxia-Sichuan-Chongqing-Yunnan-Tibet

being located in the central part of China and forming a nearly NNE-striking zone of high risk levels

and the most of other areas are of low levels of risk.
