Abstract: Based on the classical model of natural disaster risk assessment and Ningbo’s reality, this paper explores the establishment of an index system for earthquake disaster risk assessment. Delphi method and analytic hierarchy process are used to study and determine the index weight. Through the risk index, the risk level and weak links of earthquake disaster losses in different regions are relatively quantitative reflected. This paper provides reference for the formulation of countermeasures for urban earthquake prevention, disaster reduction and emergency management.
