Response operations at the 8.6-acre sinkhole in Assumption Parish were halted Tuesday after seismic monitors noted an increase in underground tremors that have been linked with “burps” and edge collapses in the yawning slurry hole, state regulators and parish officials said.
John Boudreaux, director of the parish Office of Homeland Security and Emergency Preparedness, said about five to six trees that had been leaning over for the past week along the northeast side of the sinkhole fell in Tuesday morning and that small bubbling spots also have re-emerged in the sinkhole.
“They do have a section in the center of the sinkhole that has that bubbling,” he said.
But officials with CB&I and Itasca Consulting Group Inc., who are working for the Louisiana Office of Conservation on the sinkhole emergency, said the seismic indications do not represent an “additional significant threat” to the area around the sinkhole, according to an Office of Conservation statement.
