摘要
汶川8级特大地震发生于龙门山地震带,地震灾害损失惨重,震后诱发大量次生山地地质灾害。通过笔者参加的我省宁强、略阳等县汶川震后次生地质灾害应急排查,结合区域地质、控震构造和地震活动性分析,以期对陕西龙门山地震带次生山地地质灾害特点和地震活动规律的探讨,对我省防灾减灾提供有益的帮助。
A strong earthquake measuring 8.0 on the Richter scale has rocked Wenchuan in Sichuan province, which is located in the Longmenshan seismic zone. The earthquake caused a lot of secondary geological hazards and resulted in severe aftermath. An emergency investigation of geological hazards caused by Wenchuan earthquake in Ningqiang and Lueyang counties has been carried out. The article summarizes the analysis in combination of regional geology, structures and seismic activities for further discussion on the features in geological hazards and seismic activities on the Longmenshan seismic zone in Shaanxi Province, which would facilitate disaster prevention and mitigation in Shaanxi Province.
