Synthetic Waveforms for Earthquake Early Warning Testing

SWEET is an interactive web app for finite fault modeling and synthetic seismic waveform generation. Design earthquake rupture scenarios through a map-first workflow: set location and geometry on the map, configure kinematics, group subsources, define a station network, and compute broadband synthetic waveforms.

Waveform Templates

Pre-computed templates are generated using the ML-based seismic waveform model of:
