The number of sinkholes in Florida has surged since Hurricane Irma.
Some 400 sinkholes have been reported statewide since Hurricane Irma hit in September.
Anthony Randazzo of the engineering and geology firm Geohazards says water flowing underground during such heavy rain events brings with it clay and sand.
“Once you begin to do this you promote a lack of support for the ground surface to be able to hold or support a structure,” said Randazzo.
He says the sinkholes will continue and that north and central Florida especially are prone with their old limestone that is close to the surface and rife with caverns and cavities.
