%X 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 × 1025 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.
