A Deep Learning Pipeline for Large Earthquake Analysis using High-Rate Global Navigation Satellite System Data (2503.20584v1)

Published 26 Mar 2025 in physics.geo-ph

Abstract: Deep learning techniques for processing large and complex datasets have unlocked new opportunities for fast and reliable earthquake analysis using Global Navigation Satellite System (GNSS) data. This work presents a deep learning model, MagEs, to estimate earthquake magnitudes using data from high-rate GNSS stations. Furthermore, MagEs is integrated with the DetEQ model for earthquake detection within the SAIPy package, creating a comprehensive pipeline for earthquake detection and magnitude estimation using HR-GNSS data. The MagEs model provides magnitude estimates within seconds of detection when using stations within 3 degrees of the epicenter, which are the most relevant for real-time applications. However, since it has been trained on data from stations up to 7.5 degrees away, it can also analyze data from larger distances. The model can process data from a single station at a time or combine data from up to three stations. The model was trained using synthetic data reflecting rupture scenarios in the Chile subduction zone, and the results confirm strong performance for Chilean earthquakes. Although tests from other tectonic regions also yielded good results, incorporating regional data through transfer learning could further improve its performance in diverse seismic settings. The model has not yet been deployed in an operational real-time monitoring system, but simulation tests that update data in a second-by-second manner demonstrate its potential for future real-time adaptation.
