The recent formation of two adjacent sinkholes in two days have forced several residents of the Pasco Mobile Home Park in Holiday, Florida to evacuate to a nearby hotel, as geologists predict that a third sinkhole could be opening up in the near future.

Digital Journal reports that the first sinkhole was formed early Monday in Pasco Mobile Home Park. It swallowed one of the resident’s cars in the process, with the Hyundai dropping 10 feet to the bottom of the hole. The second sinkhole formed only 25 feet away from the first one just one day later, growing an additional 10 feet throughout the day.

The cause of the recent sinkhole formations is unknown, but according to WFLA, geologists testing the soil believe that it may be due to the pumping for a new storm sewer lift system right next door to the Park.

“Whatever has stimulated this, it could have been the pumping, they were de-watering, so they were lowering the water table, that changed the hydraulics, the pressures in the ground and that might have been the trigger,” said geologist Sandy Nettles.

Digital Journal also reports that sinkholes are a common occurrence in west-central Florida because the state is underlain with porous limestone, which can hold large amounts of groundwater. “To understand what has been happening, think of the groundwater as a stabilizing force on the limestone. On top of the limestone, the land, consisting of soil, sand and clay, also exerts a stabilizing pressure. All this keeps the surface in a sort of equilibrium. Sinkholes form when the surface layer caves in.”

An official with Pasco County Utilities announced late Tuesday that they would temporarily suspend work in the area near the sinkholes. “Pasco Utilities is taking this action in the spirit of mutual cooperation into what is causing the depressions in the area,” stated spokesperson Doug Tobin.

WFLA reports that numerous evacuees from seven mobile homes are currently staying in the nearby Fairfield Inn, which is being paid for by the park’s owners.
