摘要
陷落地震是石灰岩喀斯特区溶洞或土洞塌陷所引起的特殊类型的地震,在我国南方及西南喀斯特区域分布较为广泛,是一类低震级高烈度的地震,在震中区造成较大的震灾。本文以桂林附近喀斯特区为研究范围,从古往今来的地震记录中分析提炼出其分布、形成及特征。
Karst collapse induced earthquake is a special type earthquake caused by karst or soil layer collapse. It is widely distributed in limestone zone of the Southern China and often causes quakes with low magnitude but high intensity, where the geologic hazard is quite severe. The distribution and occurrence of karst collapse induced earthquakes are abstracted from historical events in this paper.
