Regional seismotectonic context and damage associated with the 2017 Ezgeleh earthquake. (a) The blue star marks the epicenter location, and the squares represent the fault parametrization. The blue beachball is the moment tensor estimated in this study, and the brown moment tensors are regional seismicity from the Global CMT catalog (Ekström et al., 2012). The red star shows the approximate location of two historical earthquakes. The dashed black line is the Main Recent Fault (MRF), and dotted lines are supposed locations of regional blind faults (MFF = Mountain Flexure Fault; HZF = High Zagros Fault; ZFF = Zagros Foredeep Fault; Berberian, 1995). Arrows indicate the convergence of the Arabian plate (AR) with respect to stable Eurasia (EU) from the GSRM v2.1 (Kreemer et al., 2014) and MORVEL (DeMets et al., 2010) models, computed with the UNAVCO Plate Motion Calculator. LA = Lorestan Arc. KE = Kirkuk Embayment. The red dashed square indicates the position of (b). (b) Black dots are aftershocks located by the International Institute of Earthquake Engineering and Seismology of Iran. Focal mechanisms from the Global CMT catalog of three large aftershocks are shown in green. Brown colors indicate the level of damage based on a compilation of destruction rate and landslide activity interpolated from field surveys conducted by the Geological Survey of Iran (GSI, 2017). The darker the color, the more intense the damage. Blue lines are the 1.5‐m coseismic slip contour. CMT = centroid moment tensor.
