La. sinkhole emergency zone quake, bubble event stops work

Louisiana's state of emergency due to its giant Bayou Corne "sinkhole" is nearing seven months long, but the tremors, migrating methane, and expansion continue in this week's new round of environmental and human assaults that now officially extend two miles and prompted workers to be pulled off the job.

Wednesday, the state's Department of Natural Resources Office of Conservation began advising Assumption Parish officials and the public in the Bayou Corne area that the contracted CB&I and Itasca Group analysis of ongoing seismic monitoring detected what again appeared to be an uptick in underground fluid movement below the sinkhole.

Underground "fluid" appears to be moving in the vicinity of Texas Brine LLC’s failed Oxy 3 cavern over the past three days.

The advisement was publicly issued and then relayed at 1:15 P.M. Wednesday by Assumption Parish officials.

"As noted in earlier similar events, the fluid movement appears to be linked to observations of trees falling into the sinkhole, release of trapped debris from the sinkhole bottom and increased odor from hydrocarbons released to surface," the state advised, according to the Assumption Parish post on its blog.
