Diffusion Model

Broadband Ground Motion Synthesis by Diffusion Model with Minimal Condition
HEGGS is a high-fidelity generative system that produces realistic earthquake ground motion waveforms by modeling seismic signals as structured environmental sounds using a conditional latent diffusion model and waveform reconstruction pipeline.

Broadband Ground Motion Synthesis by Diffusion Model with Minimal Condition
We present HEGGS, a novel diffusion model for earthquake ground motion simulation, exploiting fundamental dataset characteristics of seismic waveforms. HEGGS works very well in many aspects: P/S phase arrivals, envelope correlation, signal-to-noise ratio, GMPE analysis, frequency content analysis, and section plot analysis.
