Analysing post-earthquake landslide activity using multi-temporal landslide inventories near the epicentral area of the 2008 Wenchuan earthquake

摘要: Abstract. Large earthquakes in mountainous regions may trigger thousands of landslides, some active for years. We analysed the changes landslide activity near epicentre 2008 Wenchuan earthquake by generating five inventories different years through stereoscopic digital visual image interpretation. From May 2008 to April 2015, 660 new landslides occurred outside co-seismic areas. In number had gone down to 66, less than 1 % but still much higher pre-earthquake levels. expect that will continue decay, be halted if extreme rainfall events occur.
