Supporting Data for: A near-real-time adaptive framework for ground motion prediction using incremental gradient boosting

This dataset contains raw and processed strong ground motion parameters of M4.0+ earthquakes in mainland China (2020–2025) from the China Earthquake Networks Center (DOI: 10.12080/nedc.11.ds.2024.0002), and a processed subset of the NGA-West2 vertical ground motion flatfile from PEER. It serves as supporting data for the paper "A near-real-time adaptive framework for ground motion prediction using incremental gradient boosting".
