The NGA-Subduction Ground-Motion Models released in Spring 2020 have been implemented and QA'd in a series of platforms: Excel, Matlab, Python and R.

Because it has been updated, Click here the MS Excel version of this tool.

All ground-motion tools compute the weighted geometric mean of the median-prediction model and the SRSS for the Sigma. The Aleatory Variability is computed for each model. The Epistemic Uncertainty is also computed for one of the models.

NOTE: All of the tools compute the values for 5% damping.
