A sinkhole that swallowed part of a house and a man in his bedroom in Seffner, Fla., could be uncovered later today. Likely caused by acidic rainwater dissolving the limestone in the earth beneath the house, located in an area called "Sinkhole Alley," the sinkhole is not "typical," said Hillsborough County administrator Mike Merrill. "This is a chasm." Between 2006 and 2010, Florida had 24,671 claims for sinkhole damage.
