~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sinkholes Appearing Around the World
How Sinkholes like Guatemala happen 2012 AUG The
gigantic sinkhole at Guatemala shocked the world. How are sinkholes
formed? Watch the mystery unfold behind one of the largest sinkholes in
Guiana Highlands ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Massive Louisiana Sinkhole Widening, swallowing 100-foot trees 2012 AUG A
Louisiana sinkhole that is 324 feet in diameter and reaches as deep as
422 feet in one corner continues to grow and caused evacuations today.
Officials believe an underground salt cavern is the reason the hole
opened up and swallowed 100-foot-tall cypress trees. The
hole first came to attention a week ago when residents noticed bubbles
in the water of the southern Louisiana bayou. Assumption Parish Sheriff
Mike Waguespack said he is worried that the hole may contain 1.5 million
barrels of liquid butane, which is a highly volatile liquid. It becomes
an extremely flammable vapor upon release. Texas
Brine Company, which mines the cavern, is investigating to see if the
circumstances are indeed dangerous. Local residents say the Department
of Natural Resources has known for months that the Texas Brine well had
integrity problems. Louisiana probes cause of massive bayou sinkhole Louisiana
officials are investigating whether an underground salt cavern may be
responsible for a large sinkhole that has swallowed 100-foot-tall
cypress trees and prompted evacuations in a southern Louisiana bayou. The
state's Department of Natural Resources ordered Texas Brine Company,
which mines the cavern, to drill a well into the cavern to see whether
it caused the dark gray slurry-filled hole nearby. Measurements
taken Monday showed the sinkhole measures 324 feet in diameter and is
50 feet deep, but in one corner it goes down 422 feet, said John
Boudreaux, director of the Office of Homeland Security in Assumption
Parish, about 30 miles south of Baton Rouge. Assumption Parish police said Thursday the sinkhole has since grown another 10 to 20 feet.
A huge sinkhole has caused the collapse of a highway in the US state of Ohio.The Department of Transportation thinks dredging for sand may have eroded land at the edge of a pond. It could be months before permanent repairs can be made.
