Publication of paper by IASBS PhD student in prestigious international journal Natural Hazards

According to a report by the Public Relations of the Institute for Advanced Studies in Basic Sciences (IASBS), a paper entitled “Calibration of Path and Site Effects and Simulation of Megathrust Earthquake Scenarios in the Makran Subduction Zone Using Stochastic Finite Fault Modeling” has been published in the journal Natural Hazards by Springer.

The Makran subduction zone is considered to be one of the most important seismically active areas surrounding Iran, and the occurrence of large earthquakes in this region could have widespread consequences for the coasts of the Sea of Oman and the south-east of the country. This research has calibrated the propagation path effects of seismic waves and site conditions by utilising real data from the Saravan earthquake, and has subsequently simulated various earthquake scenarios with a magnitude of approximately Mw≈8.

The results of this study present estimations of key earthquake engineering parameters, including Peak Ground Acceleration (PGA), Peak Spectral Acceleration (PSA), and Peak Displacement Amplitude (PDA). These data can be used in seismic hazard analysis, seismic design of structures, vulnerability assessment of infrastructure, and disaster management planning.

Among the characteristics of this research are the calibration of the model based on real regional data and the use of accurate geometric information of the Makran megathrust fault; an approach that has increased the accuracy of the simulations and made the results more reliable for future studies and engineering applications.

The paper was published in the journal Natural Hazards on 18 June 2025. This publication is in the first quartile (Q1) and has an impact factor of 4.5.

This research is the result of a collaboration between Mr Mohsen Ranjbar, Dr Khalil Motaghi, a faculty member of the university, and Dr Pengfei Dang from Northwest A&F University in China.
