'Not your typical sinkhole' that swallowed man grows deeper

Authorities in the US state of Florida are waiting to go into the 6-metre chasm to search for the man's body as family mourns.

SEFFNER, FlORIDA // Engineers worked gingerly 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.

Jeff Bush, 37, was in his bedroom on Thursday night when the earth opened and took him and everything else in his room. Five other people were in the house but managed to escape unharmed. Mr Bush's brother jumped into the hole to try to help, but he had to be rescued himself by a sheriff's deputy.

Engineers were expected at the home to do more tests after sunrise today. They spent the previous day on the property, taking soil samples and running various tests - while acknowledging that the entire lot was dangerous. No one was allowed in the home.

"I cannot tell you why it has not collapsed yet," Bill Bracken, the owner of an engineering company called to assess the sinkhole, said of the home. He described the earth below as a "very large, very fluid mass".

"This is not your typical sinkhole," said the Hillsborough County administrator Mike Merrill. "This is a chasm. For that reason, we're being very deliberate."

Officials delicately addressed another sad reality: Mr Bush was likely dead and the family wanted his body. Mr Merrill, though, said they did not want to jeopardise any more lives.

"They would like us to go in quickly and locate Mr Bush," Mr Merrill said.

Two adjacent houses were evacuated and officials were considering further evacuations. Even the media was moved from a lawn across the street to a safer area a few hundred feet away.

"This is a very complex situation," said Ron Rogers, the county fire chief. "It's continuing to evolve and the ground is continuing to collapse."

Sinkholes are so common in Florida that state law requires home insurers to provide coverage against the danger. While some cars, homes and other buildings have been devoured, it's extremely rare for them to swallow a person.

Florida is highly prone to sinkholes because there are caverns below ground of limestone, a porous rock that easily dissolves in water.

"You can almost envision a piece of Swiss cheese," Taylor Yarkosky, a sinkhole expert, said while gesturing to the ground and the sky blue home where the earth opened in Seffner. "Any house in Florida could be in that same situation."

A sinkhole near Orlando grew to more than 120-metres across in 1981 and devoured five sports cars, most of two businesses, a three-bedroom house and the deep end of an Olympic-size swimming pool.

More than 500 sinkholes have been reported in Hillsborough County alone since the government started keeping track in 1954, according to the state's environmental agency.

The sinkhole, estimated at 6-metres across and 6-metres deep, caused the home's concrete floor to cave in around 11pm Thursday as everyone in the Tampa-area house was turning in for the night. It gave way with a loud crash that sounded like a car hitting the house and brought Mr Bush's brother running.

Jeremy Bush said he jumped into the hole but could not see his brother and had to be rescued himself by a sheriff's deputy who reached out and pulled him to safety as the ground crumbled around him.

"The floor was still giving in and the dirt was still going down, but I didn't care. I wanted to save my brother," Jeremy Bush said through tears on Friday in a neighbour's yard. "But I just couldn't do nothing."

He added: "I could swear I heard him hollering my name to help him."

A dresser and the TV set had vanished down the hole, along with most of Mr Bush's bed.

A sheriff's deputy who was the first to respond to a frantic 911 call said when he arrived, he saw Jeremy Bush.

Deputy Douglas Duvall said he reached down as if he was "sticking his hand into the floor" to help Jeremy Bush. Mr Duvall said he did not see anyone else in the hole.

As he pulled Jeremy Bush out, "everything was sinking", Deputy Duvall said.

Engineers said they may have to demolish the small house, even though from the outside there appeared to be nothing wrong with the four-bedroom, concrete-wall structure, built in 1974.

Jeremy Bush said someone came out to the home a couple of months ago to check for sinkholes and other things, apparently for insurance purposes.

"He said there was nothing wrong with the house. Nothing. And a couple of months later, my brother dies. In a sinkhole."
