I haven't seen a thing about this except for a blurb in a diary, (blurbist/commenter) forgive me for not remembering your name. :(
Louisiana activates 4000 National Guardsmen, securing sinkhole equipment
The governor of Louisiana, home of an expanding, gas-bubbling sinkhole the size of three football fields with radiation levels three times the state's acceptable limit, has activated 4,000 members of the Louisiana National Guard to assist with Tropical Storm Isaac heading toward it, as officials and Texas Brine Co. work to secure the massive hole's exploratory rig and other equipment.
Because Isaac is expected to be very dangerous and is heading to Louisiana where a giant sinkhole has been bubbling and expanding out of control for weeks, the state already has activated 4,000 members of the Louisiana National Guard to assist with emergency operations, has reached out to nearby states for possibly more assistance, and officials are working with Texas Brine Co. LLC to determine if the rig at the sinkhole should be shut down, according to Gov. Bobby Jindal.This thing has lots of backstory, it's scary. They've known about it for some months.
Please do read article for more details. Just wanted to get this out there.
