TÓM TẮT
Landslide is a complex geo-hazard which impacts on
sustainable social-economic development in the mountain area.
This phenomenon is a result of a combination of critical natural and
artificial conditions of many impact factors such as topographic
attribute, infrastructure constructions, geology, land cover, and
rainfall. Estimating the contribution weights of these factors plays a
significant role in disaster management activities. This study
focuses on three provinces which are Hue, Quang Nam and Quang
Ngai which are frequently and severely impacted by landslide in
the central region of Vietnam. Historical events are investigated by
statistical analysis, field survey with supports from GIS to figure out
these significant factors to landslide occurring in the study area.
The result has illustrated landslide increases, according to the
development of human activities and long duration critical rainfall.
