Short summary
We microzoned seismic hazard of the City of Kolkata, India by integrating seismological, geological and geotechnical themes in GIS which in turn is integrated with the vulnerability components in a logic-tree framework for the estimation of both the socio-economic and structural risk of the City. The cumulative damage probabilities in terms of ‘none’, ‘slight’, ‘moderate’, ‘extensive’ and ‘complete’ have been assessed for the predominantly four model building types RM2L, RM2M, URML and URMM.
