Sinkholes: Buried Alive

Sinkholes: Buried Alive


An investigation into sinkholes, a natural phenomenon that sees the ground give away as a result of weak acid attacking the rocks below, riddling them with holes like Swiss cheese. They can occur gradually, when the surface subsides into bowl-shaped depressions, or suddenly, when the ground gives away - swallowing animals, buildings and even entire highways. This documentary features video footage of dramatic collapses and follows scientists as they explore the underlying forces behind these natural disasters.
