The Dahaizi ground fissure

which is located in the sloping area between the Qianhe's four-step terrace and the loess tableland

is now in a phase of shifting and distortion.The physical and chemical quality of the loess is fundamental to the formation of the ground fissure.Soil water storage in the terraced fields storing have created ideal conditions for its movement.Continuous rain and rainstorms cause expansion of the ground fissure.Cutoff of foot slopes through human activity major cause of fissure expansion.Once the ground fissure forms

it contributes to the passage of surface water to the groundwater system.This disturbs the water-resistant structure of the former soil surface and enahances the potential for land sliding.Due to the risks created by fissure activity

this paper suggests that housing structures should be removed from this area

the terraced fields should be reconstructed

monitoring should be strengthened and villages should be properly planned so that damage that may be caused by fissure-related natural disaster can be relieved or eliminated.
