Earthquake Origins · Tectonic Sandbox Science

A 60-second science explainer video presenting how earthquakes happen through an interactive tectonic sandbox: starting with a 3D cross-section of Earth's crust, showing plate friction and stress buildup, then fault slip releasing energy, seismic waves propagating, surface shaking relative to epicenter distance, and ending with aftershocks underground. Pursues Apple-level scientific visualization quality, ideal for science education and disaster preparedness shorts.
