Seismic disaster loss risk assessment for southeastern Tibet based on 3D image pattern recognition

LI ChangLong;LI ZongChao;Lü HongShan;GAO MengTan;Institute of Geophysics,China Earthquake Administration;  
This paper investigated the numbers,types,and vulnerability of the buildings in Southeastern Tibet and built pattern classes for difference types of buildings.Then we assessed the distribution of each type of buildings in every town based on 3D image pattern recognition,and made an event-based and a 50-year hazard-based seismic risk assessment for the towns in Southeastern Tibet.Our study indicated that if an M7.5 earthquake happened in Qusong-Sangri,it may cause serious casualties in Lhasa and Shannan area.The town of Qusong and Naidong may have the most casualties.Areas with the highest seismic risk are urban areas of Lhasa and Nyingchi and Cuona Town,and urban Lhasa has the highest seismic risk of building structural economic losses.
