3:25 p.m. Burp Occurring in Sinkhole

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)
