In the flood season of 1987

rockfal and landslide took place for 58 times in succession

but no one is harmed in Zigui county of Hubei Pro vince

which is a wonder created by the Party

the authorities and the masses in rushing to-deal with the emergency and fighting natural cala mities. It is thought that the reason of the collapsing and landsliding is mainly related to the effect of geological structure

topography and geo graphy

the damage of plantation

the intensive rainstorms

unadoptable excavation in construction and the unstable side slope immersed by watern e reservior of Guozhouba Dam

etc.
