Here's something you don't want to see at home. From Yahoo News:
Here's something you never want to hear: "That loud booming sound is coming from inside the house!"
That's what one Inocenta Hernandez from Guatemala City learned after a sudden noise caused her to run outside, thinking there had been an explosion nearby. When she realized the problem was inside her home, she returned to find a gaping, three feet wide, 40 feet deep sinkhole beneath her bed.
Hernandez, 65, was relieved that the damage was only to her house, and hadn't harmed her grandchildren, who had been playing near the bed. This was a little too close to home, but she couldn't have been too surprised that a sinkhole had visited her city.
Guatemala City is prone to spawning giant pits, which are often caused by tropical rain storms. Sinkholes are natural depressions in the earth that can range anywhere from a few feet to hundreds of acres wide, and measure a shallow foot to 100 feet deep.
Glad to see her and her grandchildren were not harmed. Sinkholes are serious business. They strike without warning. There is one thing. If you notice that there's low water pressure in your home, check with your neighbors to see if they have the same issue. There could be a water main leak/break and that could lead to a sinkhole as this story shows.
