This study has referenced the Transformer Earthquake Alerting Model (TEAM), a deep learning earthquake early warning (EEW) framework. We optimized the model using seismic data from Taiwan to develop the Taiwan Transformer Shaking Alert Model (TT-SAM), and it could rapidly calculate the seismic intensity to provide longer warning time.
We use 2016 seismic data to evaluate model performance.
Seismic intensity threshold is from Central Weather Administration.
Background color represents model predicted intensity.
