Security camera footage captured the terrifying moment when two pedestrians disembarked from a bus and fell into a sinkhole in Seoul, South Korea, late last week. They only suffered minor injuries in the incident, which happened near the Yongsan rail station, the Associated Press reports. The Korea Times reports via Yonhap News Agency that they fell approximately 10 feet. An apartment complex is being built nearby, so the Yongsan Fire Department has said authorities will check out streets in the surrounding area to see if there are any other sinkholes.
