According to the Assumption Parish Police Jury website, increased seismic activity was recorded between 6 p.m. and midnight, Tuesday. The cause of this activity is unknown at this time. The tremors occurred on the same day dangerous gases were discovered at one of the vent wells at the sinkhole. [...]
Hydrogen Sulfide is a poisonous, flammable gas and has a very bad odor. The smell is described as the smell of rotten eggs. Unlike methane, it is heavier than air and collects at low to the ground levels. No community air monitors have detected Hydrogen Sulfide.
The well was shut down due to these levels. [...]
In the meantime, DEQ is doing in-home monitoring, but residents tell WAFB 9News they believe nothing will be done until someone dies.
Texas Brine Company, Press Release, November 21, 2012:
Debris, apparently from the bottom of the sinkhole, rose to the surface accompanied by a brief period of water movement. That debris is being cleared from the surface.
