Excerpts from: Sinkhole seismic event studied

Director of the Assumption Parish Office of Homeland Security and Emergency Preparedness John Boudreaux

  • Officials first began noticing an increase in seismic activity about two weeks ago
  • Scientists reported that more than 80 seismic events were monitored two days ago
  • “There was a tremendous amount of activity over the past couple of days”
  • [T]he seismic activity has been pinpointed to shifting salt deposits just east of the failed cavern, about 900 feet into the ground
  • [C]oncern to parish officials because it indicates that something might be failing in the salt structure
  • “We would assume that in order to create seismic activity, it’s something shifting … in the salt”
  • “Not knowing what that may cause is concerning”
  • [O]fficials still believe the sinkhole won’t outgrow scientists’ predictions that it would one day measure about 1,400 feet in diameter

Wilma Subra, environmental chemist who provides technical assistance to the Louisiana Environmental Action Network

  • While officials have noticed growth in the sinkhole after seismic activity in the past, this round of activity is concerning because of its severity, as evidenced by Texas Brine’s cracked well pad
  • “The issue is that it may even go further and have an impact on the integrity of the well bore”

    To all ENE Villagers, I just finished writing the editor of the ADVOCATE News Paper in Baton Rouge to setup and help get a blog started where all scientists,first responders, fire,police,others,in saving lives could get together and put their minds to work as to coming up with some working solutions as to this disaster. It would include Government,Industry and others so as to see if we can come up with things each other can do to possibly stop this event. Or at least give it one hell of a Try.

    if i get any answers I will post it.

    8lbs. of water will absorb 3.184lbs. of salt.the salt is not shifting its saturating water making the land above the salt dome sink to create a very large man made salt water hydrocarbon lake. the people responsible need to start buying a lot of property and a lot more people will have to leave. the sinkhole growth is far from over sorry to say

    "Salt water hydrocarbon lake". Maybe Monsanto will stock it with geneticaly modified hydrocarbon resistant fish and it can become a vacation destination for sportsman and their families.
