Seismic Hazard Zoning of The Neyshabour By Definitive Method

Abstract

In order to properly design and seismic rehabilitation of old and valuable buildings, the seismic hazard zoning map is required. Since construction of the Neyshabour City have over 50 years old, and some of the historical and religious buildings ​​have their importance, and due to the presence of large earthquakes in the background seismicity of the city, the necessity of the study is obvious. The purpose of this study is the risk analysis and preparation of hazard zoning map in Neyshabour. In this study, using different sources, seismic data catalog during 1900 to 2012 in radius of 150 km of Neyshabour had been collected, and then respect to active faults, the seismic parameters were calculated in the study area. If the the north Neyshabour fault activity be at the distance of 8/82 km from the Neyshabour, Maximum horizontal acceleration resulted from that for the Neyshabour city, by 07/057Richter seismic power ,0/433g acceleration of gravity was calculated. Finally, according to the estimated PGA, the seismic hazard zoning map using Geostatistical Analyst tool in ArcGis software was plotted.
