Description

Simulated Ground Motion Dataset for the Azores Plateau
This repository contains a simulated ground motion dataset for the Azores Plateau (Portugal), for bedrock conditions. The dataset is generated using a stochastic source-based approach with randomized input parameters to capture aleatory uncertainty. Validation confirms that the dataset accurately represents real ground motion variability and inter-period correlations. This dataset supports seismic hazard analysis and risk assessment in the region.
