Seismic Geological Disaster Characteristics in MS 5.3 of Luhuo

Abstract:

Luhuo County is located in the Xianshui river fault which is a famous strong activity fault in the southwest of china. In April 10, 2011 an earthquake measuring Ms=5.3 happened near the Luhuo County , the earthquake and its secondary effect had triggered a series of geo-hazards, making the previous fragile geological environment had further deterioration and significantly increased the earthquake disaster risk of the mountain town. There are four main factors influence and control the geological disaster risks of the county, including the strong shaking effect of the earthquake fault, Qiuri River debris flows in the southern city zone, the geological hazards of Se Delong gully in the northern city zone and the group-occurring flows which threaten the county roads.
