In the video, the man can be seen walking along the street until -- within a split second -- the ground gives way and he disappears. A rescue operation reportedly was attempted, but according to CNN the man later died of his injuries.
Those unlucky enough to be standing in the wrong place at the wrong time, sinkholes are a deadly occurrence, as they strike without enough warning to escape the hole radius.
