RISK ASSESSMENT OF DAMAGE CAUSED BY LANDSLIDE IN THE MOUNTAINOUS DISTRICTS OF QUANG NGAI PROVINCE

Abstract

This work presents the initial results of the risk assessment of damage caused by landslides in the mountainous districts of Quang Ngai province.
Map damage risk in mountainous districts of Quang Ngai province was built on the basis of integrated maps with landslide risk map disaster resilience of socio-economic objects with spatial analysis in GIS environment.
Most mountainous areas of Quang Ngai risk level low and very low losses, accounting for 65.64 % of the area , high and very high levels accounted for only 15.08 % of the natural area . Son Ha District at risk of damage caused by the landslides highest in the study area, followed by Tra Bong district . District Son Tay risk of damage to a minimum.
These areas are at risk of damage caused by the landslides at high and very high concern when planning resource utilization territory, sustainable development of socio-economic and environmental protection: the Tra Phong, Tra Lanh and Tra Quan (Tay Tra district), Tra Son, Tra Thuy and Tra Lam (Tra Bong district), Son Tan, Son Mua (Son Tay district), Di Lang, Son Bao, Son Thanh, Son Thuong and Son Ha (Son Ha district); Long Hiep and Thanh An (Minh Long district), Ba Vi , Ba Vi and Ba To town (Ba To district).
