Opis

A systematic approach of seismic microzonation is explained in this book. A case study conducted is described with results and discussion. In the present study, seismic hazard analysis of political capital city of Kerala, south India is carried out using deterministic approach. Using the vulnerable source ground motion is simulated by stochastic finite fault simulation method. The ground motion is simulated at rock level for 100 sites within the study area. Using the Geographic Information System (GIS) software the rock level acceleration is mapped for study area. The influence of local soil condition on ground motion is studied by one- dimensional ground response analysis. The results obtained from seismic hazard analysis and ground response analysis at 100 locations of the study area is used to prepare the microzonation maps of the city in GIS environment.
