Analysis from Itasca Group on recent seismic monitoring that can be posted to Assumption blog to give information to public on latest evaluation –

Dr. Will Pettitt, Principal Geophysicist at Itasca Consulting Group, has reviewed the seismic data recorded overnight on November 20/21. Long-period seismic tremors and micro-earthquakes have been observed, similar to those defined previously by Dr. Steve Horton of CERI/USGS, and recorded mainly on station LA08 closest to the sinkhole. The long-period seismic tremors are postulated to be caused by gas and/or fluid movements through the rock collapse zone below the sinkhole on the edge of the salt dome. Micro-earthquakes of this nature are typically associated with small-scale rock movements, and again are believed to be occurring in the collapse zone. The source of both of these event types continues to be investigated by experts.

Doesnt sound like they too concerned. Texas salt has been told to continue plugging wells.
