slip distribution of the 2010 august 27 mw 5.8 kuh-zar earthquake from finite-fault modeling

Abstract. the slip distribution of a moderate earthquake in iran, the 27th of august, 2010 mw 5 : 8 kuh-zar earthquake, was estimated from regional broadband seismic data using constrained non-negative least squares linear slip inversion method. a great many inversions were carried to determine the optimal parameters used in the process such as rupture velocity and rise time. a rupture velocity of 2.55 km/s and rise time of 1.8 s were utilized for the event. results show a rupture with peak slip of 15.0 cm and total seismic moment release of 2 × 10^25 dyne-cm. the effect of the stations with different epicentral distances was also analyzed using a sensitivity test. due to the non-uniqueness of the inversion problem, a set of solutions is presented for the kuh-zar earthquake. to the best of our knowledge, this is the first time to consider constrained non-negative least square linear finite-fault inversion procedure to the kuh- zar earthquake.
