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

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. As a result, recognizing uncertainties and how they...

description 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. As a result, recognizing uncertainties and how they are considered by different risk analysis methods can indicate the reliability of those methods in seismic hazard assessment. Fuzzy logic is a suitable tool that is used as a decision-making method for solving problems and modeling uncertainties and ambiguities. Nowshahr Port is located in the Alborz seismic province which is one of the seismic regions in Iran. In this study, a seismic hazard estimate for a range of 200 km radius from Nowshahr port was carried out at a latitude position of 34-38 degree north latitude and 49- 54 degree east longitude. For this purpose, 16 potential seismic sources have been used in the studied area. First, seismic hazard estimation was done by the Conventional deterministic method and then using fuzzy logic. According to the results obtained in the conventional deterministic method, Peak Ground Acceleration values estimated from Conventional deterministic method 0.52g and 0.55g application fuzzy Logic System.
