source inversion of m7.3 12 nov. 2017 sarepol-e zahab earthquake using fuzzy inversion method

On 12 nov. 2017 an m7.3 earthquake shook sarpol-e zahab city in north-western zagros seismogenic area, near iran- iraq border line. the earthquake killed more than 600 people and the strong motion was widely felt in kermanshah and kurdistan provinces of iran as well as major city of sulaymanieh in iraq. before this earthquake, no high-magnitude (>7.0mw) earthquake was recorded in this area (nissen et al., 2019), and the causative fault was not completely knownbefore (gombert et al., 2019) while the epicentral region is surrounded by a complex set of faults. in order to study the co-seismic displacement within the rupture of this earthquake, a kinematic source model is found by fuzzy inversion method (fim) (navid kheirdast et al., n.d.) using geodetic satellite data (insar) from sentinel-1 and strong-motionrecordings of bhrc in the frequency domain. the fuzzy inversion method helps to decrease the effect of ill-posedness in the source inversion problems, where the effect of non-uniqueness and instability will be controlled which results in a more reliable dislocation model. fim helps in determining the ruptured area by distinguishing it within the inversion process.
