( CNN ) -- The sinkhole first opened up in August of 2011 , a relatively small thing , 2 feet wide and 5 feet deep . But in the 15 months since then , Florida couple John and Tina Furlow have watched helplessly as the sinkhole expands , threatening to swallow their bedroom . `` Now it 's approximately 8 , 9 feet long , '' John Furlow told CNN affiliate WFLA last month at their home in Hernando County on Florida 's west coast . `` Every day , in our bedroom , we lay down and look up and there 's more and more cracks . We 're just , 'hey look , there 's another one , ' '' said his wife . The growing cavern underneath their bedroom is reminiscent of another sinkhole in nearby Hillsborough County that claimed the life of Jeff Bush . Sinkholes : Common , costly and sometimes deadly . Authorities demolished the house after they could n't recover Bush 's body from the massive hole that opened up under his bedroom . That sinkhole was about 20 feet wide and 50 to 60 feet deep , and the suburban Tampa house was in danger of collapsing . For the Furlows , the nightmare has developed much more slowly . Cracks have begun to appear on walls and floors , and the couple now sleeps in a different bedroom . They removed heavy furniture from their bedroom in hopes of buying more time . The couple told WFLA that they made a claim with their insurance company , but that a year and a half later there has been no resolution . A sinkhole can be catastrophic , as the incident that took Bush 's life showed . New video obtained by CNN affiliate Bay News 9 shows the inside of the sinkhole that claimed his life . The video was taken by Hillsborough County officials before the house was demolished . It was recorded by attaching a camera to a pole that reached into Bush 's bedroom through a window . The video shows a cavernous hole that left just the edges of the floor around the bedroom . Bush 's brother , Jeremy , had jumped in the hole to try to rescue his brother , but only after he saw the video did he understand how large it was , and why officials pulled him out . `` It is totally different than what I thought it was , '' he told Bay News 9 . Sinkholes are common in the state , according to the Florida Department of Environmental Protection . Florida lies on bedrock made of limestone or other carbonate rock that can be eaten away by acidic groundwater , forming voids that collapse when the rock can no longer support the weight of what 's above it .
