Abstract

The main goal of this paper is to evaluate the seismic parameters of Sanandaj, Iran. For this reason, at first, all the occurred instrumental earthquakes (1900-2006) in a radius of 200 km of Sanandaj city have been gathered. After elimination of the aftershocks and foreshocks, the main earthquakes were taken into consideration to calculate the seismic parameters by Gutenberg-Richter method, cumulative distribution functions, and Kijko-Sellevoll approach. This paper aims at estimation of seismicity parameters based on the seismic events and the relation between the cumulative frequency of earthquake occurrence and its magnitude. For this purpose the variable windows in time and location domains are employed, and the earthquakes are supposed to follow Poisson’s formulation. Subsequently, the seismicity coefficients for Gutenberg–Richter, cumulative distribution functions, and Kijko–Sellevoll methods are calculated and the magnitude–period graphs are constructed. These results serve to illustrate the need to carefully reassess the reliability of seismicity parameters using them for seismology, or seismic-hazard purposes.

Evaluating Seismicity Parameters of Sanandaj, Iran Based on Instrumental Earthquakes

San Diego, California

The main goal of this paper is to evaluate the seismic parameters of Sanandaj, Iran. For this reason, at first, all the occurred instrumental earthquakes (1900-2006) in a radius of 200 km of Sanandaj city have been gathered. After elimination of the aftershocks and foreshocks, the main earthquakes were taken into consideration to calculate the seismic parameters by Gutenberg-Richter method, cumulative distribution functions, and Kijko-Sellevoll approach.
