10 Most Amazing Sinkholes on Earth

Bimmah Sinkhole, Oman

The Bimmah Sinkhole occurred naturally in the town of Dibab in Oman. It is located in the middle of Muscat and Sur. The sinkhole, for some reason, has nice and clear blue waters. As a result, residents and authorities have cashed in and turned the place into a swimming park that attracts both local and foreign tourists.

Sarisarinama Sinkholes, Venezuela

In a tepui in Venezuela are four wonders that feature sinkholes. The flat-topped mountain is actually more popular because of these. Two of the four, namely the Sima Humboldt and the Sima Martel are huge, with the former measuring 352 meters in width and 314 meters in depth. The two have isolated forest ecosystems covering the bottom. Another sinkhole called the Sima de la Lluvia measures 1.35 kilometers long. It is being used as the basis of research of scientists who are exploring the process of erosion on tepuis.
