Dangerous Holiday, FL Sinkhole
In November 2013, a sinkhole opened up in a driveway in Holiday, Florida. The 63 year old woman that lived there saw that the tires of her car were sinking into the cement. A few minutes later, her entire car was swallowed by a 10 foot by 10 foot hole in the ground. Several homes needed to be evacuated, fearing that more sinkholes would form.
Sinkholes are prominent in the state of Florida due to the limestone that the soil is made up of. They are formed by the erosion of the limestone as water travels downward into the limestone causing the erosion. There are three types of sinkholes:
Collapse sinkholes appear suddenly, often making the headline news such as the one in November in Holiday, Florida. These types of sinkholes form when surface material suddenly sink into a cavity or cave.
Solutions sinkholes form slowly from the sandy sediments that cover the limestone bedrock. Cracks and voids begin to form beneath the top layer. The sinkholes appear slowly from the sandy sediments. Groundwater then washes away the sediments creating larger voids and cavities beneath the ground.
Subsidence sinkholes are similar to solutions sinkholes. The difference is that they contain a thick layer of soil that covers the limestone bedrock. As water enters the cavity, it dissolves weak areas and the overlying sediment gradually moves downward into the growing cavity, making it larger over a period of time. Often, they become ponds as water fills into the cavity.
There are a few waning signs that a sinkhole may be forming around you and your home. Some of these signs are:
- Sidewalk and driveway cracks – Cracks in your sidewalk or driveway may indicate that there is sinkhole activity forming.
- Neighbors with sinkholes – If your neighbor has a sinkhole, it is important that you have your property inspected.
- Soft spots in the yard – Look for spongy or soft spots in your yard. This could indicate sinkhole activity.
