What's amazing about the following story is how such a near perfect round hole of such great depth can form within a matter of minutes? What kind of process is going on inside the Earth to cause these sinkholes to form?
From Guardian UK: Sinkhole, 12m (36 feet) deep and 80cm (2.5 feet) in diameter, forms at Guatemala City home of 65-year-old Inocenta Hernandez
You may sometimes wish the ground would swallow you up, but for some the danger of disappearing down a deep hole is all too real.
The people of Guatemala City are increasingly unable to trust what's beneath their feet because of treacherous sinkholes.
The latest person to get a shock was 65-year-old Inocenta Hernandez. "When we heard the loud boom we thought a gas canister from a neighbouring home had exploded, or there had been a crash on the street.
"We rushed out to look and saw nothing. A gentleman told me that the noise came from my house, and we searched until we found it under my bed."
A reporter for AFP news agency who visited her home, estimated the hole, which appeared late on Monday, was 12.2m (40ft) deep and 80cm (32inches) in diameter.
"Thank God there are only material damages, because my grandchildren were running around the house, into that room and out to the patio," said Hernandez.
Others have not been so lucky. A giant sinkhole that formed nearby in 2007 was 150m deep and swallowed several homes and a truck, killing three people. Local residents were forced to evacuate for days.
