Karst collapse in Borneo

A large sinkhole collapse in Sarawak, on the Malaysian island of Borneo, almost led to the loss of c.100 lives. A traditional longhouse, occupied by around 100 people, was quickly evacuated after a man, taking a late night trip to the toilet, raised the alarm when he felt the earth move beneath him and saw the end of the longhouse sinking into the ground.
