'World's deepest' underwater sinkhole found in China

Sinkhole in Florida

A sinkhole has reopened in Florida in what officials are saying was an underground cave. The massive hole is 25 feet wide and 80 feet deep. This same sinkhole opened up for the first time last June as workers drilled a nearby well. Another sinkhole, in near by Seffner, Florida also reopened for the third time in 10 year, this past July after swallowing a man in 2013. #sinkhole #florida #Lakeland | NBC 6
