Earthquake Risk Analysis of Building Houses using Probabilistic and Deterministic Approach (Study Case: West Sumatra, Indonesia)

Abstract

Over the past decade, West Sumatra experienced a major earthquake event with significant risk. Disaster risk analysis needs to be done with the aim of minimizing disaster risk. This study aims to model the distribution risk of building houses damages and economic losses. Risk analysis is carried out quantitatively with probabilistic and deterministic approaches with faults and subduction zone sources based on Seismic Hazard Analysis (SHA) method. The use of probabilistic and deterministic approaches is done for providing a better risk analysis perspective and regarding to earthquake disaster management policy making. The results found that the earthquake risks are greater from fault earthquake sources compared with subduction earthquake sources.
