Residents in a central Florida neighborhood have been forced from their homes by giant sinkholes.

At least six holes opened last week in the Wynchase subdivision in Ocala. Six more have formed since then.

The large holes have been forming around a retention pond and some are filled with water, according to WFTV-TV.

"They just keep coming," resident Maren Pinder told WFTV.

"Are we safe? We don't know. It's really scary."

A video posted to Facebook by Kelly Rippin shows water in the retention pond bubbling and then mud and dirt exploding into the air shortly before the sinkholes formed.

People have been evacuated from eight homes. American Red Cross volunteers have been helping those residents.

City leaders are still trying to figure out how to fill in the sinkholes and stop them from developing again.

Geotechnical engineers worked all day Monday to secure and test the holes.

Some news reports indicated the problem could be caused from an irrigation water main break, but officials are still investigating.

The homeowners association in 2012 paid thousands of dollars to fill sinkholes. Officials say it could cost more this time. They said the holes can't be filled until they know the ground has settled.

"We just have a bag ready in case they say, ' Yeah, you need to evacuate.' We can just grab it and get out," Pinder said.
