Dear authors,
your manuscript titled ‘Estimating Ground Motion Intensities Using Simulation-Based Estimated of Local Crustal Seismic Response’ describes an alternative approach to obtain ground motion models for seismic hazard assessment that does not rely on the existence of elaborate earthquake catalogs. I am fully invested in moving away from relying solely on information from past earthquakes and moving towards a physics-based solution able to sample the investigated area with high resolution. With modern advances in computing power, a simulation-based approach is becoming a very realistic alternative. I appreciate the author’s detail to theoretical considerations. My main advice would be to be a bit more specific in how a potential reader could apply this workflow. The easier it is to adopt the approach, the wider it will get used. Attached are some specific comments that may help you.

Short summary

Rapidly expanding cities in earthquake-prone regions of the Global South often lack seismic event records, hindering accurate ground motion predictions for hazard assessment. Our study demonstrates that, despite these limitations, reliable predictions can be made using simulation-based methods for small (sub)urban units undergoing rapid development. High-resolution local geological data can reveal spatial variability in ground motions, aiding effective risk mitigation.
