Abstract:
On 3 Aug 2014 an earthquake with a magnitude of 6.5 occurred in Ludian.And on Oct.7.2014 magnitude 6.6 earthquake occurred in Jinggu.The two earthquakes occurred in mountain area with little difference in magnitude.By analyzing the scale,amount and degree of the landslide disaster,we can get four reasons.difference between natural and human environment,lithology difference,difference of landform,and difference in vegetation.Landslid occurred around the Ludian earthquake area frequently,mainly due to huge terrain elevation,wide distribution of basalt and carbonate rocks,and river erosion,frost physical(frost)weathering and chemical weathering.
