Preliminary report of Mw7.3 Sarpol-e Zahab, Iran earthquake on November 12, 2017 Mehdi Zare Professor of Engineering Seismology, International Institute of Earthquake Engineering and Seismology (IIEES), and Associate member of Academy of Sciences of Iran. e-mail: mzare@iiees.ac.ir Farnaz Kamranzad Ph.D Student of Mineral Exploration Engineering, Department of Mining Engineering, College of Engineering, University of Tehran. e-mail: f_kamranzad@ut.ac.ir Issaak Parcharidis Associate Professor of Space based Earth Observation Applications, Harokopio University of Athens, Department of Geography Varvara Tsironi Msc in Msc in Dynamic, Tectonic and Applied Geology 2017 Sarepol-e Zahab Iran earthquake On November 12, 2017, at 18:18 UTC (21:48 Iran Standard Time), a major earthquake with the moment magnitude of 7.3 occurred in Kermanshah province of Iran. According to the National Center of Broadband Seismic Network of Iran, the epicenter of this event was located at 34.88°N and 45.84°E near the Iran–Iraq border with a depth of 23 km. The epicenter has a distance of about 5 km to the town of Ezgeleh 43 km from Sarapul-e Zahab city and 46 km from (Fig 1), Qasr-e-Shirin city. The focal mechanism solutions for this earthquake indicate a fault dipping shallowly to the east-northeast, or on a fault dipping steeply to the southwest. Based on the active fault map of Iran, this earthquake can be triggered by the movement of the Zagros Mountain Front Fault (MFF) in Pol-e-Zahab Region. This event that continued for 30 seconds, was felt in an extended area in Iran, Mesopotamia, the Caucasus, eastern Turkey, Iraq and Syria. Until November 20, 2017 (8:00 a.m. UTC time), about 460 aftershocks with magnitudes over 2.5 have been recorded by the Iranian Seismological Center (IRSC) The largest magnitude of this earthquake's aftershock (Fig 2). sequence was 4.7, which occurred November 13th.
