Researchers are using thunderquakes and fiber-optic cabling to image Earth's subsurface structure, leveraging software models and seismic sensing from thunderstorms.
Introduces Decoupled Latent Optimization (DLO) for full waveform inversion, which relaxes latent optimization into a quadratic-penalty objective, outperforming classical and diffusion-based methods on benchmarks while preserving smoothed-velocity initialization.
