Last year, I remember that there were two sinkhole incidents happened in Florida. It was big news at that time but, it was immediately off the news for no one was hurt. Sinkholes are common here in Florida. I was thinking about us so; I always pay attention if there are cracks in our property. Thank God that there was none and so far, it never occurred nearby our neighborhood. What happened in Tampa in Feb 28 was a different story. Jeff Bush, 28 was swallowed by the sinkhole while he was asleep. His brother Jeremy Bush tried to help him but, because it was too deep, they can't reach to him.
Sinkholes are geologic hazards and can cause extensive damage to structures such as houses, roads and to prevent this from happening is very hard because they just appear from nowhere.
It is scary in fact after the sinkhole incident in Florida, Pennsylvania sinkhole follows and this time, in the property of Doris Jenkins in Bethlehem Township.
Sinkholes are common where the rock below the land surface is limestone. If there are carbonate rocks, salt beds, or rocks that can naturally be dissolved by circulating ground water and as the rock dissolves, spaces and caverns develop underground. Sinkholes are found all over the world. If you Google it and watch the images of sinkholes, you will be overwhelmed as to the number of incidents all over the world.
