Work continues near sinkhole that swallowed man in Florida bedroom
SEFFNER, Fla. — Engineers worked gingerly Saturday to find out more about a slowly growing sinkhole that swallowed a Florida man in his bedroom, believing the entire house could eventually succumb to the unstable ground.
It could be days before officials decide whether they will attempt to recover Jeff Bush’s body, and they were still trying Saturday to determine the extent of the sinkhole network and what kind of work might be safe. As the sinkhole grows, it may pose further risk to the subdivision and its homes.
Bush, 37, was in his bedroom Thursday night in Seffner — a suburb of 8,000 people 15 miles east of downtown Tampa — when the earth opened and took him and everything else in his room. Five others in the house escape unharmed.
Because of Florida’s unique geography, experts say sinkholes are common across the state, with thousands erupting each year. Most are small, though, and deaths rarely occur.
“There’s hardly a place in Florida that’s immune to sinkholes,” said Sandy Nettles, a geologist. “There’s no way of ever predicting where a sinkhole is going to occur.”
Florida is prone because it sits on limestone, a po- rous rock that easily dissolves in water. A layer of clay is on top of the limestone. The clay is thicker in some locations — including the area where Bush became a victim — making them even more prone to sinkholes.
Most are small, like one that was found Saturday morning in Largo, some 35 miles away from the Seffner sinkhole. The Largo sinkhole, about 10 feet long and several feet wide, was discovered in a mall parking lot. Such discoveries are common throughout the year in Florida, though some factors — such as drought and development — can exacerbate the development, according to the U. S. Geological Sur- vey.
Still, it’s unclear what, if anything, caused the Seffner sinkhole.
“The condition that caused that sinkhole could have started a million years ago,” Nettles said.
On Saturday, Hillsborough County Fire Rescue spokesman Ronnie Rivera said one of the homes next door to the Bush house also was compromised by the sinkhole, as determined through testing. The family, which had evacuated Friday, was allowed to go inside for about a half-hour to gather belongings, Rivera said. The family was outside, crying and organizing boxes.
Engineers had been testing since 7 a.m. Saturday.
