These models use cohesive sand above a buried zone of glass microbeads to model lateral spread-type failure during earthquake shaking. When the model is accelerated, the microbeads lose all frictional strength and behave like a liquid or slurry beneath the brittle overlying material. The slope along the edges of the model embankment allows low angle sliding to occur.
Videos are shown at about 1/2 speed. The "sloshing" behavior of the slides during shaking is cool to watch.
