英文摘要	The 12November2017 M(w)7.3 Ezgeleh-Sarpolzahab earthquake is the largest instrumentally recorded earthquake in the Zagros Simply Folded Belt by a factor of approximate to 10 in seismic moment. Exploiting local, regional, and teleseismic data and synthetic aperture radar interferometry imagery, we characterize the rupture, its aftershock sequence, background seismicity, and regional tectonics. The mainshock ruptured slowly (approximate to 2km/s), unilaterally southward, for approximate to 40km along an oblique (dextral-thrust) fault that dips approximate to 14 degrees E beneath the northwestern Lurestan arc. Slip is confined to basement depths of approximate to 12-18km, resolvably beneath the sedimentary cover which is approximate to 8km thick in this area. The gentle dip angle and basement location allow for a broad slip area, explaining the large magnitude relative to earthquakes in the main Fars arc of the Zagros, where shallower, steeper faults are limited in rupture extent by weak sedimentary layers. Early aftershocks concentrate around the southern and western edges of the mainshock slip area and therefore cluster in the direction of rupture propagation, implying a contribution from dynamic triggering. A cluster of events approximate to 100km to the south near Mandali (Iraq) reactivated the approximate to 50 degrees dipping Zagros Foredeep Fault. The basement fault responsible for the Ezgeleh-Sarpolzahab earthquake probably accounts for the approximate to 1 km elevation contrast between the Lurestan arc and the Kirkuk embayment but is distinct from sections of the Mountain Front Fault that define frontal escarpments elsewhere in the Zagros. It may be related to a seismic interface underlying the central and southern Lurestan arc, and a key concern is whether or not the more extensive regional structure is also seismogenic.
