Spatiotemporal Seismic Hazard Assessment Using VQ-VAE and Seismic Statistical Features
Researchers have developed a new method for assessing spatiotemporal seismic hazards by integrating seismic statistical features (SSFs) with a VQ-VAE model. This approach refines predictions to localized areas, focusing on a 24 km radius around candidate events. The study demonstrates that the VQ-VAE derived feature, which captures spatial seismic map information, significantly enhances prediction performance and can largely replace traditional methods like the b-value calculation.
