Scared of Sinkholes?
The recent death of Jeff Bush in a Florida sinkhole has highlighted the dangers of these natural phenomena. Although sinkholes cause an average of 17 insurance claims a day in Florida alone, deaths are rare.

Thirty-two-year-old Sonia Lopez was driving down the road in Boise Idaho when her car hit a sinkhole that had suddenly appeared in the road. After investigation, authorities decided that the hole was formed when gopher tunnels filled with irrigation water from nearby farms. The combination of the two elements caused the road to becoming unstable and suddenly collapse. Lopez died from her injuries.

Guatemala City residents were shocked to find a 30-story sinkhole suddenly appear. Two people died in the incident. The hole was caused by sewage and water eroding the bedrock underneath the ground.
What Causes Sinkholes?
According to USGS, sinkholes are often the results of water events such as floods or hurricanes. The water enters the ground and begins to dissolve the rock underneath, leaving air pockets that will eventually collapse. Rocks that can be dissolved by water include “salt beds and domes, gypsum, and limestone and other carbonate rock.”
Underground caves, either man-made or natural, can also collapse because of water activity, pressure, and erosion.
Sinkholes can also be caused by human activity such as mining, well digging, and even the draining of water tables in periods of drought.

Outline maps of Florida's counties, displaying sinkholes of varying sizes. Some counties contain no sinkholes, and therefore do not have a sinkhole map associated with them.
Can Anything Be Done?
The best defense, according to authorities is to look around for tell-tale signs of formation. Signs of sinkholes include: “sagging trees or fence posts, doors or windows that no longer close properly, and rainwater collecting”
Some sinkholes can be filled in and the damage contained.
To prevent sinkholes in areas that are prone to them, insure that your home and property have good drainage.
Deaths Are Rare
Anthony Randazzo, a former University of Florida professor, points out that deaths from sinkholes are thankfully rare. Randazzo notes that they usually don’t appear suddenly and that paying attention to warning signs will help keep you and your family safe.
Will Climate Change Bring More Sinkholes?
Deadly sinkholes often make the news because they are rare, scary, and seem unpredictable. While sinkholes have always been a natural occurrence, modern society and urban sprawl have made us much more aware of them.
As the world becomes more populated, people live in more and more areas susceptible to them.
Changing weather events associated with climate change such as floods and hurricanes may mean that we will see an increase in these over the next few years as water continues to move and change the land.
Questions & Answers
Question: I live in Kentucky. Can you tell me which part of the state is more prone to sinkholes?
Answer: I know that the eastern part has more limestone. That can erode over time and cause sinkholes. I'm not sure about the western half of the state.

I didn't die, I got injured!

All right, pip pip and cheerio my good fellows, I've seen a lot of sinkholes in my home town really helped me understand the causes of it. Really scary stuff. I never knew. Invigorating. Definitely something to be aware of. Information was super helpful.
Keely Deuschle from Florida on December 31, 2013:
This is a very interesting article. I, like you, live in Florida and have good friends that live in Seffner where the one that killed Jeff Bush happened. Ever since then, it has certainly heightened my awareness. Hearing a few more open up there is quite scary. On a smaller scale, we see them more often from broken water mains that may collapse a road. Thank you for including the things to look for, as that should certainly help people to look for warning signs that there may be something to be concerned with.

Thanks moonlake. It does seem to be a problem that many parts of the world are facing. It is worrisome because just like earthquakes there is very little time to prepare--or even no time. It's disheartening every time I read about another life claimed by these sinkholes.
moonlake from America on November 30, 2013:
Interesting hub I didn't know even that many had died from sink holes all across the country. Voted up.

Thanks grand old lady. Living in Florida, I hear nearly every week of sinkholes and sinkhole damage, especially in the central part of the state. As our water sources are depleted, it may get worse since the underground hollows where the Florida aquifers are may collapse. It seems that there isn't much to do but watch and wait but as you pointed out and I pointed out in the article, there are ways to notice if the earth is changing around you. Hope all your family came through the typhoon okay and are not having to deal with too much clean up and aftermath. Thank you for stopping by.

I first learned about sinkholes when the story of the Florida man who was in his bedroom fell in. It was very sad and also scary. This article does a good job in explaining sinkholes, what causes them and signs to look for that may indicate the presence of sinkholes. The weather is so crazy these days. The video was also good in showing how sudden and unexpectedly a sinkhole can occur. Thank you for this article:). I will share it in my family tree FB page, since many of them are from Cebu and the areas that were hit by the typhoon Haiyan.
L C David (author) from Florida on April 22, 2013:
I know. It really does seem like they are random (and maybe some of them kind of are).
I'm glad deaths are rare but it is sad that they still happen.
Jim Laughlin from Connecticut on April 21, 2013:
Wow! Crazy stuff, great Hub!
L C David (author) from Florida on April 13, 2013:
Yes, the one in Florida piqued my interest as well. I think the scary part about them is just how random they really are. The footage of the Taiwanese man falling into the sinkhole is horrifying to me!
Thanks so much for stopping by, Glenn Stok.

I became interested in learning more about sinkholes due to the recent one in Florida. You hub was very informative. You gave the information I was looking for -- basically States that have sinkholes, and some known causes.
We take our planet for granted. The earth is very volatile. Even though some sinkholes are caused by human intervention, it can happen due to natural causes too, as you had shown with the examples.
