| 摘 要： | 地震次生地质灾害主要指地震引起的崩塌、滑坡、塌陷、地裂缝、砂土液化。震级大干5级、烈度超过Ⅵ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NE向高危险带，其余大部分地区为轻度危险区。

| Abstract: | Earthquake-induced secondary geological disasters include avalanches,landslides,caving-in,ground cracks and liquefaction of sand.The earthquakes of magnitudes>5 and intensity>VI may lead to occurrence of various scales of geological disasters.The higher the magnitude and intensity are,the secondary geology disaster will be more serious.Based on the extent and occurrence conditions of secondary geological disasters induced by historic earthquakes in China,the danger assessment has been made with the city,prefecture and meng(league)as the unit.The high and moderate danger areas are mainly distributed in the Shaanxi-Gansu-Ningxia-Sichuan-Chongqing-Yunnan-Tibet region in the central part of China,forming a nearly NE-trending high danger zone,and all other remaining areas are low danger areas. |
