Experts are looking into the cause of recent rumbling in the ground near the massive sinkhole in Assumption Parish.
A scientist with the Center for Earthquake Research and Information reported there has been above-normal seismic activity around the site for several days. [...]
Texas Brine’s Feb. 3 Update (h/t The Bugle): “[Cavern] floor had risen 100 feet since last measured on Jan. 18.”
A 100-foot rise over a 15-day period is an average of almost 7 feet per day. Previously, the cavern floor had been rising at a rate of less than 1 foot per day (Sources: 1, 2, 3).
