The Office of Conservation, in consultation with Assumption Parish Incident Command, is advising the public that the Oxy 3/sinkhole monitoring alert status has been raised to Code 2 – requiring all work directly on the sinkhole to cease until further notice. Seismic monitoring has detected an increasing trend of micro-earthquake (MEQ) activity in the area around the sinkhole and Oxy 3 over the past few days.

Such activity has previously been noted as a likely indication of shifting and sloughing in the sinkhole and the area below it. The seismic activity is limited to the Oxy 3/sinkhole area, showing no indication of impact to the Oxy 1 area. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions.
