Classification of landslides induced by China Wenchuan2008 Earthquake basing on landslide-quake
2008.5.12 Chinese Wenchuan earthquake was characterized by high magnitude of Ms 8.0,shallow focus of 14km,long duration of about 120s and strong destruction.More than 15000 landslides was induced by this catastrophic earthquake resulted in serious lives and properties lost.According to statistics,over 300 landslides were characterized by large volumes,of which 112 landslides have a sliding area of more than 50,000 m2.These large earthquake-induced landslides differ from general gravity-induced landslides by fluidization characteristics,rapid departure,long run out and catastrophic results.Although earthquake-induced landslides vary in volume,geological set,texture of rockmass,enduring force,moving direction,traveling velocity and distance and fluidization properties,there should be some disciplines all landslides follow in enduring force,occurring time,mechanism for rapid departure,traveling characteristics,etc.Basing on the investigations of Whenchuan earthquake-induced landslides,the various phenomena of these landslides are firstly analyzed,and then landslide-quake is newly produced,basing on which mechanism for rapid departure of different type of earthquake-induce landslides is studied.The landslides mentioned in this paper are those directly induced by the earthquake,and other landslides induced by water and other factors are excluded.
