Footage captures sinkhole swallowing trees in Louisiana swampThursday 22 August 2013 12.20
Authorities in the US have recorded dramatic footage of a sinkhole swallowing up trees and land in a Louisiana swamp.
The footage, shot by the Assumption Parish Office of Emergency Preparedness, captures the moments when the sinkhole swallows the trees in a furious 30 seconds of swirling water.
Louisiana state officials believe that the sinkhole, which has been widening over the past year, has been caused by the collapse of an underground salt dome.
The salt dome is believed to have collapsed due to excavation work carried out by a company called Texas Brine. Louisiana State is currently suing the company.
