| Abstract: | 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. |
| Keywords: | Mt Longmenshan seismic zone secondary geohazard geological structures |
