Why Sinkholes Collapse
On 24 September 2025, a massive sinkhole opened outside a Bangkok hospital, swallowing vehicles, damaging infrastructure and forcing nearly 1,000 people to evacuate. This film investigates its causes, exploring how collapsing tunnels, ageing sewers, abandoned mines, groundwater depletion and urban development contribute to the growing global threat of city sinkholes
