Abstract

The paper presents the approach for earthquake hazard, exposure, vulnerability and risk assessment for Nepal. The approach amalgamates various scientific streams, which are structured and integrated on GIS platform. The exposure, vulnerability and risk assessment are carried out for primary sectors including population, housing, education, hospital, industry, power and roadways. The risk assessment is carried out in two ways targeting emergency management agencies. One aspect of risk assessment represents expected number of sector units falling in specific grade of damage and the second aspect covers expected loss and impact on GDP due to large magnitude earthquake (i.e., Bihar-Nepal Earthquake 1934). The earthquake risk for the size of the 1934 event may mean losses exceeding 15 billion USD, can lead to large fiscal and economic impacts. Based on these findings the paper recommends DRR interventions at the national scale to tackle gaps in risk reduction, risk financing and risk governance.
