“A spokesman for brine says only five of its original 53 vent wells are still picking up gas, the breached cavern is filled with sediment, and that the sinkhole has not grown in ten months.”

Something happened – medium tremor – at Lake FUBAR after 12:15 p.m. – shown on LA17-02

Reader, Harriette reports there was a big fat 4.3 quake (frack-quake) in Oklahoma right then. Mystery solved. Louisiana is in big trouble if Lake FUBAR is going to get shook up over all those big frack-quakes over there!

Something ELSE happened at 6:49 p.m. there – something quite big. Not fluid motion or a far away quake. See the same helicorder – –



Almost 20 minutes after midnight something twanged again at Lake FUBAR. A sharp jolt…. shows well on the LA17-01 helicorder. The Gulf of Mexico quake didn’t show up at all (see later post above )

Film crew visits Bayou Corne site
By David J. Mitchell
The Public Broadcasting Service television series NOVA is focusing its documentary lens on the nearly 2-year-old sinkhole in northern Assumption Parish.
A film crew associated with the venerable, award-winning science program finished up four days of interviews and shooting in Bayou Corne on Friday, said NOVA producer Larry Klein. A one-hour program is set to air in the winter of 2015. . . .

“. . .  Never one to be left out, the sinkhole also had a say in the NOVA shoot. Tremors last week delayed the crew’s attempts to use an aerial drone to shoot over the sinkhole. Klein said things calmed down enough eventually to get the shot. . . “

Stuart Smith – Bayou Corne, natural gas, and the law of unintended consequences

[snip] “. . . .  One of the saddest environmental tragedies to touch the Deep South in recent years has been the small Louisiana community of Bayou Corne, about 70 miles west of New Orleans. Over the last two years, a massive sinkhole, shaking the earth and emitting dangerous amounts of potentially explosive methane, has forced 350 residents to abandon the homes where some had lived their entire lives. The sinkhole was clearly the result of years of extraction at an underground salt dome by the Texas Brine Co., and then structural issues that had been ignored by the firm and by state regulators. But just now are researchers finding out specifics about what actually caused the sinkhole — and the results are troubling:

To find out what might have caused these tremors, scientists analyzed data gathered by a temporary network of seismic stations that the U.S. Geological Survey had set up in the area. The scientists detected 62 tremors — which ranged in magnitude from 1.3 to 1.6 — in the day before the sinkhole was discovered.

Unexpectedly, the scientists found that the tremors originated about 1,540 feet (470 meters) beneath the western edge of the Napoleonville salt dome.

The seismic data suggested that the sinkhole-linked quakes were caused by explosive events similar to volcanic eruptions. While hot magma causes volcanic eruptions, these sinkhole-linked quakes were apparently triggered by high-pressure gushes of either natural gas or water charged with natural gas.

The surges of natural gas that caused the tremors may have weakened the salt cavern and caused its collapse. Alternatively, a collapse of part of the salt cavern may have caused a nearby gas pocket to give off surges of gas, later followed by the complete collapse of the salt cavern.

These findings are striking for a couple of reasons. For one thing, it comes as scientists are also learning more about how the fracking process is intrinsically linked to swarms of earthquakes, many in areas that has seen little seismic activity before the drilling boom. . . . “
