This is mind-blowing. I do not see how such a giant hole could form
with this shape: a giant, deep, round shaft, big enough to swallow up
a 3-story building.
Sinkholes are common in Georgia and Florida but I have never heard of
one like this. As far as I know they are caused by an underground
flow of water. The water hollows out a volume of earth which then
collapses from above. I do not see how it could hollow out such a
huge volume without the collapse occurring earlier than it did.
In Atlanta, antiquated sewer and broken water lines cause sinkholes
and sudden collapses. Several years ago one opened up suddenly in a
parking lot downtown, where dirt and asphalt had been piled on top of
the pipeline for years, finally breaking it. The hole opened suddenly
and a pedestrian fell in and was swept away. I do not think the body
was ever found. It sounds like something from a horror movie but it
really happened.
