A massive 70-foot sinkhole has opened in the parking lot of a Florida supermarket - and the cavernous void is growing by the hour. When it first developed Thursday morning in front of a Publix in Winter Haven - outside Tampa, the hole was just 30 feet wide and less than five feet deep. By the afternoon, geologists and engineers say the depression had spread to 70 feet wide and 15 feet deep and it has shown no signs of stopping. www.dailymail.co.uk/news/article-2643149/Massive-70-foot-sinkhole-opens-supermarket-parking-lot-growing-larger-hour.html
