Seismic hazard estimation for Mumbai city

摘要

This article presents an engineering approach to estimatethe existing seismic hazard for Mumbai city. After as-sembling a catalogue of past earthquakes and analysingthe database statistically, the recurrence relation forthe control region is found out. This is used to com-pute the probability of ground motion that can be in-duced by each of the twenty-three known faults thatexist around the city. Final results are presented in theform of peak ground acceleration and response spectra,for two different return periods. These results can bedirectly used by engineers as basic inputs in earth-quake-resistant design of structures in and aroundMumbai.
