Abstract

An important key to determine the disaster risk is exposure. It is truly dynamic in space and time due to the expansion and change of the settlements. A seismic hazard is an earthquake disaster that able to deliver damage to the physical environments. Hence, it required to analyse the objects exposed by an active earthquake source in the Bandung Basin. The exposed objects that experience the most impact due to the shock of the earthquake are residential buildings. The West Bandung Regency was opted as our study area due to the high-risk zone for earthquake waves based on the calculation of seismic hazard. This paper tried to analyse the seismic exposure as the impact of earthquake waves around the Bandung Basin on residential housing in the West Bandung Regency using a geospatial analytics approach. The result shows that the settlements areas that heavily prune to earthquake shocks are located in the Tanjung Jaya. The Tanjung Jaya area has a high population density. Due to this, the appropriate disaster risk reduction mitigation strategies can be achieved.
