Dramatic footage from Kenya shows a large ground collapse forming a deep cavity as water rushes into the opening. Such events can occur when underground layers of soil or rock are eroded, creating hidden voids beneath the surface that eventually give way. As water flows into the cavity, it can accelerate erosion and cause the collapse to expand further. Incidents like this highlight the powerful forces of geology and water erosion that continuously reshape the landscape, sometimes with little warning.
