Neo-deterministic seismic hazard assessment studies for Bangladesh

The Neo-Deterministic Seismic Hazard Assessment (NDSHA), developed at University of Trieste (UT), has emerged as an attractive tool for predicting the ground motion for given seismic sources and known earth structure. This method, a computationally intensive procedure, is based on physical modelling of wave propagation and seismic source process. Under ongoing research and academic collaboration program between UT and BUET, NDSHA studies have been performed for Bangladesh. This chapter briefly presents significant results obtained under this initiative. Results obtained are compared with the seismic zoning map in the updated Bangladesh National Building Code (BNBC-2020). The seismicity and seismo-tectonics of Bangladesh and adjoining region is also briefly discussed.
