Hi guys. I am a geologist in Turkey and unfortunately we have the same problem in Konya city. We have huge sinkholes like the ones shown above. We are now anaylsing those structures in order to prevent a probable danger to people. The most important mistake made here in Turkey is the excess pumping of farmers. So the water table reduces drastically that results in sudden failure of carbonate rocks. Farmers must use the water carefully. They shouldnt irrigate the soil excessively but should use modern techniques and decrease the water amount used for watering. I am open to all scientists who are concerned with this problem and anyone can reach me throuh my email address to ask me anything about the sinkholes in Turkey. Best regards.

This sinkhole does not rival the ones you have featured on this page, but it is uncanny how it managed to open up directly underneath the only car in the vicinity.

The Quattra depression isn”t really a “sinkhole” though it might considered a sink, i.e. a former lake basin like Death Valley or the Dead Sea. Filling it with salt water would cause some huge changes in the climate of the Sahara desert, It would be a great experiment.

Also karst is a process of dissolution of rock not a type of bedrock. In Florida the bedrock is limestone, which is soluable in fresh water. Water dissolves caves and the caves collapse creating sinkholes. Karst is the process named for region in the Balkans (former Yugoslavia) but the process occurs in many regions, notably Central America and southeast China in the Gaulin Province and in the northern part of Vietnam adjacent to the Chinese border.
