Officials say tremors recorded in Assumption Parish since late May could be why a brine cavern encased within the Napoleonville salt dome failed and caused a massive sinkhole.
Texas Brine Co. spokesman Sonny Cranch said Tuesday a tool used to measure the depth of the cavern bottomed out 1,300 feet higher than anticipated. Cranch said the presence of this material indicates the cavern failed.
Officials say an abandoned brine cavern in the Napoleonville salt dome has been successfully breached.
State Commissioner of Conservation James Welsh said Monday the investigatory well entered the cavern Saturday evening. Officials say they hope samples taken from inside the cavern will shed some light on the cause behind a massive sinkhole that erupted in Assumption Parish Aug. 3.
Officials say natural gas samples taken from inside the cavern will be tested for connections with gas bubbles that have been identified in other areas of the parish.
