11:45 a.m. Advisory from the Office of Conservation

The Office of Conservation is advising the public that the Oxy 3/sinkhole monitoring alert status has been lowered back to Code 1 – allowing work inside and around the sinkhole to resume. The rate of subsurface activity being detected by seismic monitoring is reduced in the area around the sinkhole and Oxy 3 area, and the waters of the sinkhole have not shown further signs of movement at surface. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions. The public is also being advised that the 3D seismic work is planned for Sunday, March 24, involving the use of boat-mounted pneumatic equipment on the waters of the sinkhole to generate the seismic signals used to help assess the status of the disturbed rock zone near and below the sinkhole.
