-- back at home now a second sinkhole opening up in Florida about two miles from the one -- swallowed part in this home on Thursday night literally swallowing a man alive.
Meanwhile we're getting a closer look at the original sink hole about thirty feet wise had to be about a hundred feet deep.
The family members of the victim -- the dropping flowers and pictures into the ground there Jeff bush only age 37 has not been found.
We're hearing his body is unlikely to ever be located at afforded now jury blacks a geologist vice president environmental field.
Operations geo hazards incorporated sir good morning to you I -- a show a map to our viewers in a moment here.
I'm but what what do we need to understand about sink holes I guess specifically in Florida because it so happens so often.
-- calls happened in Florida commonly because the bedrock -- Underneath that does the surface is limestone -- -- naturally soluble.
And cavities conform in limestone because the ground water in the rain water.
Seep through the soil make the cavities and the missing -- happens win.
-- soil above fall into those cavities and normally that the size and the occurrence has to do with how close the limestone is to the surface.
So I see okay so that that accounts for the variation here let let me just share our viewers.
A map here going back to 1954.
All the blue dots you see here in the state of Florida.
That is where the same calls have been found -- reported going back in 1954.
So they're up here around Tallahassee Leon County many here in Central Florida the -- -- -- though.
And this to be Tampa -- saint -- where there's a good number of them here and also just at the northern section there.
Sir can you.
No win a sinkhole is going to give way is there some sort of detection device or is it usually a surprise.
Well -- the collapse sink -- are you know very hard to predict but they're also the slower subside and sink holes.
That form over time and do you know have you can get small -- -- the surface and you can see cracks in your home.
Before if something else happens.
Looking at that map the dots are indicated that.
Indicative of where the limestone is close to the surface.
And then now I for court or and then especially in the Spring Hill -- Hernando Pasco and Tampa area once it was close to the surface and you can have.
The smaller ones.
But even in the eastern part of the Hillsborough County you can have the cover collapse.
-- just went and a hundred feet deep with the one that we've been reporting on the last couple of days I mean it's striking when you think about and they've been searching for this man's body for days they never found him.
Jerry thank you Jerry black get a Gainesville Florida and that -- and again we.
