Earthquake vulnerability in the Himalaya by integrated multi-criteria decision models

Himalayan mountains are one of the most seismo-tectonically active zones on surface earth. Recurring moderate and high magnitude earthquakes not uncommon in this region. This paper maps earthquake vulnerability region using integrated multi-criteria decision models. Factors which may influence a can be categorized social, geotechnical, structural, physical parameters. We have used analytical hierarchy process (AHP) approach to determine weights various parameters, were further develop for study area VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR), Grey Relational Analysis (GRA) methods. There is good correlation between estimated through AHP-VIKOR AHP-GRA Our analysis indicates that more than 12% under very-high vulnerability, whereas 44% population, about 43% buildings highly vulnerable hazards due earthquakes. The results would useful hazard mitigation infrastructure planning agencies working
