Sinkholes are generally caused by water eroding soft limestone or unconsolidated deposits from beneath, causing a hole that works its way upwards and eventually opening spectacularly at the surface. Where there are unconsolidated deposits at the surface they can infill from the sides, apparently swallowing objects at the surface, including people, without trace.
On this occasion the incident happened when heavy rain in the area caused a drainage pipe beneath the road to rupture, allowing water to wash away soft sediments beneath the road, leading to the collapse.
