Evaluation of Deterministic seismic hazard in Nowshahr Port by using fuzzy system [PDF]

open access: yesمخاطرات محیط طبیعی, 2019
The purpose of the seismic hazard analysis is to predict the extent of the strong ground movements over a certain period of time on a specific site. There are uncertainties in all the inputs of the risk analysis, each of which expresses a property.
