A selected dataset of the Iranian strong motion records

Empirical model for frequency content estimation of strong ground motion records of Iran

“…The Iran plateau is compressed by the Arabian and Eurasian tectonic plates. The tectonic activities of the Iran plateau were mainly controlled by the convergence of the Arabian and Eurasian plates that leads to moderate to large shallow crustal earthquakes by the strike-slip and reverse faults (e.g., Berberian, 2014;Zafarani and Soghrat, 2017). The recent Sarpol-e Zahab earthquake (2017, M w = 7.3) triggered significant damages in the western of Iran where the Arabian and Eurasian plates collide (Zafarani et al, 2020).…”

“…The Iranian Strong Motion Network (ISMN) which is now part of BHRC was established in 1973 to record earthquake input motions by installing of recording stations. More than 10,000 three-component time series of acceleration, which includes a pair of horizontal acceleration and one vertical acceleration components, were recorded by ISMN in Iran during 1975-2013(Zafarani and Soghrat, 2017. Moreover, more than 1700 three-component time series of acceleration were recorded by more than 833 stations during 2013-2019.…”

“…The multi-resolution wavelet analysis (Ansari et al, 2010) was used to eliminate unsuitable noise from the earthquake records. This analysis was also employed by Zafarani and Soghrat (2017) for the filtering of the Iranian earthquake records. Moreover, the baseline correction was made for all used records.…”

Merging data and experts’ knowledge-based weights for ranking GMPEs

“…In this study, a database from Zafarani and Soghrat (2017) is adopted. The authors collected ground-motion records from Iranian earthquakes between 1975 and 2014 through a comprehensive study.…”
