Probabilistic and Deterministic Seismic Hazard Assessment: A Case Study in Babol

Abstract: The risk of earthquake ground motion parameters in seismic design of structures and Vulnerability and risk assessment of these structures against earthquake damage are important. The damages caused by the earthquake engineering and seismology of the social and economic consequences are assessed. This paper determined seismic hazard analysis in Babol via deterministic and probabilistic methods. Deterministic and probabilistic methods seem to be practical tools for mutual control of results and to overcome the weakness of approach alone. In the deterministic approach, the strong-motion parameters are estimated for the maximum credible earthquake, assumed to occur at the closest possible distance from the site of interest, without considering the likelihood of its occurrence during a specified exposure period. On the other hand, the probabilistic approach integrates the effects of all earthquakes expected to occur at different locations during a specified life period, with the associated uncertainties and randomness taken into account. The calculated bedrock horizontal and vertical peak ground acceleration (PGA) for different years return period of the study area are presented.

Babol is one of the town in Mazandaran province that of the Gutenberg- Richter method
