Robert Stewart of the Advocate-Baton Rouge reports on an increase in seismic activity at the Bayou Corne sinkhole in Louisiana.  The sinkhole has been growing since it first opened up in early August, 2012.  150 homes were evacuated the day after the sinkhole appeared.  Stewart writes:

“Scientists believe the restless, 8.5-acre sinkhole in Assumption Parish swampland is undergoing a “growth event” after they noticed an upswing in seismic activity in the past few days within a brine-mining cavern carved into the massive Napoleonville Dome, parish officials said Saturday.”

The article sites officials who monitored 80 seismic events over the last few days in the area.   The Bayou Corne sinkhole is close to salt dome mining sites.  Stewart continues:

“The dome, a large underground salt formation, was pushed up vertically from ancient sea beds and, for decades, industry has used the dome for brine production. The perimeter has also been the focus of intensive oil and gas exploration.”

Louisiana Environmental Action Network is calling for a relocation fund to be set up for Bayou Corne residents.   LEAN writes:

“Texas Brine Company and Occidental Chemical Corporation should relocate Bayou Corne residents who wish to leave their community. It has been almost 6 months that the community of Bayou Corne has been displaced due to the sinkhole. Many residents of this area had found an idillic place to live in Bayou Corne but feel their sense of safety and community has been shattered forever. While Texas Brine and the State of Louisiana work to address this situation there are still many uncertainties and no definitive end in sight to the threats facing the Bayou Corne community.”
