That Sinking Feeling

Sinkholes Around The World


There are two basic types of sinkholes: (1) A cover-subsidance sinkhole and (2) a cover-collapse sinkhole.

Most are naturally occurring, but humans can contribute.




Harwood Hole - Abel Tasman National Park, New Zealand. 183 m deep.


The Devil's Hole sinkhole near Hawthorne, Florida.


Teiq Sinkhole - Oman, Jordan. One of the largest sinkholes in the world by volume - 90 million cubic meters. 250 m deep.


Blue Hole - Dahab, Egypt. 130 m deep on the edge of the Red Sea. Free diving attempts often prove fatal.
