There has been another burp that occurred and is continuing on the sinkhole. All operations have been pulled from inside of the sinkhole until activity calms down. The monitoring/alert status has been heightened to Code 3.
Below is a definition of the codes:
Code Levels are 1-3, with Code 1 being the lowest level of alert.
Code 1: Minimal to no seismic activity around/below sinkhole; 10 or fewer of the sharp seismic signals associated with rock movement, called mini-earthquakes (MEQs) or the longer signals associated with gas or liquid movement, called Very Long Periods (VLPs) within 24-hour period; allows work on sinkhole and inside berm area to continue
Code 2: Restricts work directly on the sinkhole, indicates some increased seismic activity around/below sinkhole but not at a level that indicates imminent threat of sloughing or movement below sinkhole (10 to 50 MEQs or VLPs in 24 hours)
Code 3: Restricts all work inside the containment berm, indicates seismic activity has elevated to a point similar to what has been seen in past monitoring prior to a sloughing on the shore or movement beneath sinkhole (More than 50 MEQs or VLPs in 24 hours)
