How Surface Waves Unlock Earth's Deepest Secrets

Think seismic waves only mean disaster? Think again. The most destructive shaking on Earth is actually our sharpest lens into the deep interior. Slide 1: Earthquakes do not just level cities. They are natural planetary CT scans. Slide 2: Textbooks lied to you. Seismic waves do not travel through neat, flat layers. Real topography completely warps them. Slide 3: Breaking the bottleneck. High-order 3D finite-volume modeling can finally map unstructured real-world terrain without melting supercomputers. Slide 4: Surface waves reveal what body waves miss, from glacial rifts in Greenland to oil reservoirs and hidden tectonic belts.
