This is the horrifying moment a sinkhole opened under the feet of a couple simply walking along a pavement.
The incident was filmed by security cameras in the Yongsan area of Seoul in South Korea on 20 February, CNN reports.
The pair are seen stepping off a bus and then walking just a few feet before the ground beneath them opens.
Despite tumbling ten feet, the man and woman were treated in hospital for just minor injuries, local media reports.
ITV writes the sinkhole was found next to a construction site where two 39-storey apartment blocks were being built.
It adds Seoul Metropolitan City officials and Korean Geotechnical Society members are investigating how the sinkhole occurred.
Sinkholes are cavities in the ground usually caused by water erosion.
