A site‐amplification model for shallow crustal regions that considers both linear and nonlinear soil effects is proposed. The original functional form of the was developed by Walling et al. (2008) (WAS08) using stochastic simulations site‐response analysis. major difference between proposed WAS08 our expression entirely based on empirical data. To comply with this objective, a database most recent V S 30 information from pan‐European region has been compiled. This feature encourages its use...
The 2023 Türkiye earthquake sequence includes the 6 February M7.81 mainshock followed approximately 9 h later by an M7.74 event, and many smaller aftershocks including M6.81 M6.37 events on 20 February, respectively. These occurred in a region near plate boundary of East Anatolian Fault, proximity which numerous ground motion recording stations had been installed north Türkiye–Syria border. As result, were well recorded both fault at rupture distances up to 582 km. We describe available...

We updated the earthquake strong-motion database of Türkiye (SMD-TR) that is initially compiled by Akkar et al. The data set consists 9244 earthquakes magnitudes 3.0 ≤ M 7.8 occurred between 1976 and 2023. It includes 95,890 three-component waveforms recorded at 1022 stations (55,375 records are processed from 6710 events 974 stations). disseminated under research-oriented website DesignSafe ( https://doi.org/10.17603/ds2-f21x-s189 ) to provide ground-motion flatfile, which will be...
Probabilistic seismic hazard models (PSHM) are used for quantifying the at a site or grid of sites. In this study, methodology is proposed to compare distribution expected number sites with exceedance observed considering an acceleration threshold set recording The method applied France and Turkey. French accelerometric database checked produce reliable data set. addition, we also synthetic inferred from instrumental catalogue combined ground-motion prediction equation. results show that...
A global dataset which is composed of more than 20,000 records used to develop an empirical nonlinear soil amplification model for crustal earthquakes. The also includes the deep effect. nonlinearity formulated in terms input rock motion and stiffness. defined by pseudo-spectral acceleration at site condition (PSArock) modified with between-event residual. Application PSArock simplifies usage diminishing need using period-dependent correlation coefficients hazard studies. stiffness expressed...
Using a global dataset, we propose series of ground-motion predictive models for acceleration response spectra. The proposed include regional adjustments to source, path, and site terms with nonlinear soil behavior. regression coefficients are computed using linear mixed-effect algorithms. Furthermore, develop heteroscedastic variability between-event, site-to-site, single-site standard deviations. between-event sigma model depends solely on magnitude, but the deviation both magnitude...
