Massive Sinkhole Opens in Florida

Less than 1 mile (1.6 km) from where I live, a massive sinkhole opened up last week in an area of the city where sinkholes are not typically found. The sinkhole has been growing larger by the day, and six homes are now in danger of being consumed by the massive sinkhole. So far, one swimming pool and a gazebo have fallen down into the hole. All of the families have been evacuated from those homes for their safety. The sinkhole is now 195 feet wide (60 meters), and appears to have no bottom. One resident described the massive hole as "a portal directly into hell." Geologists are on site trying to find out more information about the hole and what lies underground. It is currently suspected that a previously unknown "underground river" may be flowing through the area.
Florida is located on a massive limestone base. Over the centuries, rainwater seeping through the ground dissolves away the limestone deep under the earth, creating massive underground caverns. Because Florida has spent most of its history submerged below the ocean's surface, the soil is very sandy and loose. However, there is a subterranean layer of hard clay just above the limestone base that helps keep the sandy soil intact. When the limestone underneath it dissolves, the sandy soil is easily displaced. In many instances, the hard layer of clay is able to support the surface soil (sort of like a cap on a hole), but eventually the stress and weight of surface soils and structures will weaken the clay and it gives way.
Sinkholes are very common throughout Florida, but most are much smaller than this current one. The photo shows an aerial view of the sinkhole taken a few day ago. In one corner of the photo you can see the swimming pool teetering on the edge. That pool has since been consumed by the sinkhole. The tree that has toppled over into the hole is approximately 50 feet (15 m), giving some perspective to the size of the sinkhole.

@Courtlynn And now we have a November tropical storm coming at us. It's like 2020 doesn't want to go away quietly. It's throwing everything at us that it can.

@wolfgirl569 I'm sure you would have some type of indication that the sides would start giving away and the sinkhole starts growing bigger. Maybe you would feel the earth moving under you, or maybe you would see sand inside the hole start to shift or fall into the hole, or something.

I would. Just to take a peak over the side and into the hole. I certainly wouldn't want to live near it though.

It’s still growing larger, but so far no homes have been consumed by the sinkhole. But the hole is getting dangerously close to one of the homes, and with an approaching tropical storm later this week, it can’t be good news for the situation.

When sinkholes are small they can pump them full of sand, grout and concrete to stabilize the hole, but this one is so large that they can't do anything about it. Geologists have determined that there is a huge underground cavern deep underneath the area where the sinkhole is. There's no telling how big it can get and how much longer it will keep growing. It is still getting bigger by the day. And even worse, we have a tropical storm coming that is going to dump a lot of rain on the area, which is going to exacerbate the problem.

@Hannihar No, they cannot stop this one now. It's too big. They just had to demolish two houses that were in danger of collapsing into the sinkhole. Four other houses are still in the danger zone. The sinkhole continues to grow bigger by the day, averaging about 1.5 feet of expansion per day.

None of those six homeowners have sinkhole insurance. All are claiming that they never even heard of sinkhole insurance, and are questioning why it was never mentioned to them when they bought their houses. I agree that it should have been made aware to them at their closings that they should consider getting sinkhole insurance (I have it for my house). The city is providing free legal help for the homeowners affected by the massive sinkhole, and I think if it can be shown that none of them were told about sinkhole insurance that they will all eventually file lawsuits.

@moffittjc I would fight it too. I think insurance should be exactly that. Insurance. To cover whatever might happen to your house. Fire, flood, sinkholes, the furnace blowing up. All of it.

@porwest I agree. That's the whole point of insurance. Except that when you read the fine print in most insurance policies, they exclude more than they include. Pretty sad.

The properties have already been condemned, so unfortunately those poor homeowners have lost the full value of their homes.

All this Science means that constructions in Florida need to have firm base. Also, uncontrolled constructions can create situations like above and that is not going to be good for the public and the area administrators.
Somehow I feel that modern development has ignored such scientific things and hence this creates uncomfortable situations for all.

In some of the crowded areas in some of India's big cities, some structures are constructed with substandard material and weak foundations.
And some of these collapse, killing folks in the process. Yet Greedy construction companies/contractors still do not mend their ways.

@moffittjc I told my husband about this and he had seen something on tv about these Florida sinkholes. I truly hope that this was one fluke sinkhole in your area. Hope everyone stays safe out there . . . is there any way to test for these sinkholes?

Yeah, it's pretty close. What worries me is this is an area without a history of previous sinkholes. Makes you feel very uncomfortable knowing that no place in Florida is truly safe from sinkholes.

I think the area I'm in is mostly safe, but technically anywhere in Florida can be prone to sinkholes. Most are much smaller than this big one that opened up, and most of the time they catch them early enough where they can stabilize the ground to prevent them from growing bigger. But this one is a massive one, and really there is nothing they can do at this point other than let nature run its course.

I think there was a sinkhole in NYC recently but not that huge. I definitely don't want one around.
This one is huge. Good thing there was no house on top of it. I remember hearing something a while back... a man went into his bedroom and a sinkhole opened up and he fell into it... Don't remember where that happened though.

Yes, the sinkhole is full of water now. At first it was dry, and then it was filling up at night but draining during the day. Then when the hurricane came through, it filled up and pretty much has stayed filled up since then.

That looks quite scary. I thought maybe it was a result of the hurricaine. At least everyone was evacuated. I hope they seekers stay away too.
The pool looks like a house to me.

@MarshaMusselman Sinkholes have a direct connection to our underground aquifer, which is where all our drinking water comes from. Houses are full of toxic materials that could contaminate the water supply if the sinkhole swallowed one up.

They had to demolish the house with the pool, because the sinkhole was about to swallow it. They also demolished one other house that was also in danger of being swallowed up. The sinkhole continues to expand at a rate of 1.5 feet per day.

What a scary sight to see. I remember when visiting Florida seeing a news story on TV about a sinkhole which swallowed up a home and a person with it. Unlike a hurricane or tornado they seem to occur gradually. I hear they call the Tampa region "Sinkhole Alley?"

Yes, the central Florida area (including Tampa) is known as sinkhole alley, because they are more frequent in that area, but they do happen all over the state. The area I live in up here in north central Florida is also very prevalent to sinkholes. Most of the time they do occur gradually, but in some cases (like this current giant sinkhole) they open up suddenly without warning. That was also the case in the story you referred to when the sinkhole opened up suddenly and swallowed a house with a man inside sleeping in his bed.

Geologists call it Karst Topography when the ground and the bedrock have a gap and the ground collapses. The resulting "sinhole" is a Karst. I grew up in Indiana, sinkholes there are more common than in Florida, but are natural not caused by humans sucking all the water out of the ground!

I'm very familiar with Karst Topography, as that is the dominant makeup of the ground here in north Florida where I live. That is why we have so many sinkholes around this area. Part of our sinkhole problem is natural, and part of it is manmade. I think our groundwater pumping is simply speeding up the process a little bit.

@Nevena83 They have evacuated all the houses around the sinkhole. The residents are allowed to go back into their houses during the day to retrieve their belongings, but they cannot remain there overnight. The sinkhole will probably swallow at least six houses before it's all over.
