In thisstudy, seismological aspects ofthe 2017 Sarpol-e Zahab earthquake has been investigated. The Sarpol-e Zahab earthquake, of magnitude (Mw), occurred in southwestern Iran on November 12, 2017. Here, we investigated the properties of the strong ground motions of the earthquake using the records provided by Iranian Strong Motion Network (ISMN). | JSEE Vol. 20, No. 2, 2018 Strong Motion Records in Sarpol-e-Zahab Earthquake Mohammad Pourmohammad Shahvar 1*, Attieh Eshaghi 2, Esmaeil Farzanegan 2, and Hossein Mirzaei Alavijeh 2 1.

The Sarpol-e Zahab earthquake, of magnitude (Mw), occurred in southwestern Iran on November 12, 2017. Here, we investigated the properties of the strong ground motions of the earthquake using the records provided by Iranian Strong Motion Network (ISMN). At Sarpol-e Zahab (SPZ) station, about 30 km south of the epicenter, the recorded pea k ground accelera tion (PGA) and peak ground velocity (PGV) in both horizontal and vertical components were remarkably large, and visual inspection of the velocity time history reveals a pulse-like shape. Besides, the response spectra of the recordings were determined and were compa red to the 2800 seismic code spectrum. Furthermore, the earthquake engineering parameters for this earthquake were estimated and were compared with the values of other large destructive earthquakes in Iran. Finally, based on the recorded strong motion data and observed information such as the macroseismic intensity, ShakeMaps of this earthquake have been generated, which clearly shows the most affected areas that needed the immediate assistance and aid after the earthquake. These maps are fundamental for earthquake rapid response procedures and the earthquake crisis management. 1. Introduction On Sunday November 12, 2017, at 18:18:16 UTC, (21:48:16 local time), a strong earthquake with Mw occurred in .
