Our paper in the Journal of Earthquake Spectra presents an enhanced broadband stochastic ground motion simulation model.

Key features:

• Practical for situations with limited seismological information.
• Useful for representing ground motion variability in advanced structural analyses.
• Capable of simulating diverse ground motion types, including near-fault and far-field records, with pulse-like or non-pulse-like characteristics, and multiple strong-motion phases.
• Avoids case-specific adjustments, providing a practical and straightforward approach that is easy to implement in engineering practice
• The Python package SGSIM, implemented using object-oriented programming (OOP), is publicly available on GitHub with instructions for the improved stochastic ground motion simulation model. Users can access the latest released version on GitHub and/or Zenodo.

The model’s performance is validated using recordings from the February 2023 Türkiye earthquake and the pulse-like NGA-West2 database.
