The Bayou Corne Sinkhole: A massive oil and gas disaster you’ve probably never heard of
Earlier this spring, residents of a rural community in Louisiana's Assumption Parish noticed mysterious bubbles rising to the surface in some bayous. Shortly thereafter, a series of small earthquakes shook the area, prompting state officials to investigate. But in Early August, the ground suddenly opened up and gave way — swallowing up acres of swamp forest. In its place there is now a gaping sinkhole filled with water, underground brines, oil, and natural gas. But this was no natural disaster, say geologists. It was the consequence of mining activities conducted by the oil and gas service company, Texas Brine.
Located about 45 miles south of Baton rouge, the Bayou Corne Sinkhole has grown to eight acres in size. In the weeks following the collapse, officials determined that an unstable and collapsing salt cavern was responsible — what prompted Texas Brine to blame seismic activity on the sinkhole.
But as Mike Ludwig from Truthout reports, the United States Geological Survey (USGS) has determined that it was the collapse of the cavern that caused the tremors felt in the neighborhood, and not the other way around — what was likely brought about by extensive mining.

The giant Louisiana sinkhole’s water is far saltier the deeper the hole gets, state environmental regulators said Monday. “Salinity estimates based on water samples taken earlier this month from a large sinkhole in northern Assumption Parish suggest the water becomes far saltier, even more than in the waters of the Gulf of Mexico, the deeper the hole gets, state environmental regulators said Monday,” reports David Mitchell for The Advocate. Louisiana Department of Environmental Quality officials said those... more »

Earthquakes in the New Madrid Seismic Zone
The New Madrid seismic zone of southeast Missouri and adjacent States is the most seismically active in North America east of the Rockies. During the winter of 1811-1812 three very large earthquakes devastated the area and were felt throughout most of the Nation. They occurred a few weeks apart on December 16, January 23, and February 7. Hundreds of aftershocks, some severely damaging by themselves, continued for years. Prehistoric earthquakes similar in size to those of 1811-1812 occurred in the middle 1400's and around 900 A.D. Strong, damaging earthquakes struck the southwestern end of the seismic zone near Marked Tree, Arkansas in 1843 (magnitude 6.3), and the northeastern end near Charleston, Missouri in 1895 (magnitude 6.6). Since 1900, moderately damaging earthquakes have struck the seismic zone every few decades. About twice a year people feel still smaller earthquakes that do not cause damage.
Earthquakes in the central and eastern U.S. are typically felt over a much broader region than in the western U.S. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast. A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 100 km (60 mi) from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 500 km (300 mi) from where it occurred, and sometimes causes damage as far away as 40 km (25 mi).
Earthquakes everywhere occur on faults within bedrock, usually miles deep. The earthquakes of the New Madrid seismic zone occur within a large network of faults called the Reelfoot rift. The rift formed about 500 million years ago, when this region was stretched in the northwest-southeast direction. Along a northeast-southwest zone at least 70 km (40 mi) wide and 500 km (300 mi) long, the rocks in the rift were slowly dropped down about 1-2 km (1 mi) along some of the faults. Now the region is undergoing east- west shortening, and the ancient faults of the Reelfoot rift are being reactivated to generate earthquakes. Today the Reelfoot rift and the New Madrid seismic zone are 2,000 km (1,200 mi) from the nearest plate boundary, which is in the Caribbean Sea.
The network of faults in the seismic zone is buried beneath hundreds to thousands of feet of sand and mud. Four of the largest faults are recognized as alignments of abundant small earthquakes, and movements along two of these faults dammed rivers and created lakes during the earthquakes of 1811-1812. A few more deeply buried faults were detected during oil and gas exploration, and a few small faults are known from geologic mapping. However, many earthquakes occur away from the few known faults, so there must be additional, unknown faults that can generate earthquakes in the seismic zone. Accordingly, the best overall guide to seismic hazard in the New Madrid seismic zone is the earthquakes themselves.

Tiptonville folks don't dwell on potential danger
TIPTONVILLE - Warren Douglas has lived in a danger zone nearly all his life.
|Helen Comer/The Jackson Sun
The earthquakes of 1811 and 1812 helped form Reelfoot Lake
Since childhood, he has heard the stories, both fact and fiction, about the big earthquakes that helped form Reelfoot Lake. The facts intrigue Douglas as well as the scientific community, which warns of a recurrence of the Reelfoot quakes - today, tomorrow or 500 years hence.
"As far as people in this area worrying about earthquakes, other than being on a bridge or inside a two-story building, nobody really thinks much about it," Douglas said.
After all, it has been 194 years since the Tiptonville area was all shook up. Anxiety levels tend to wane over time, except when tremors regularly serve as a reminder.
The big three
It was about 2 a.m. on Dec. 16, 1811, when the first of three powerful earthquakes terrified the Indians and small number of pioneers who had settled in the Reelfoot region. About 400 residents made up the town of New Madrid in Missouri territory, across the Mississippi River from what is now known as Tiptonville. The three earthquakes are believed to be the most powerful to ever occur in the United States, and they were accompanied by hundreds of smaller quakes.Reelfoot Lake
"A lot of people think there were only one or two earthquakes, but there were over 1,800 earthquakes recorded in a 4 1/2 month period between Dec. 16, 1811, and March of 1812," Douglas said. "Five of those quakes were said to range from 8 to 8.7 (in magnitude). They were enormous earthquakes, some of the largest in world history."
The December quake was followed by major shocks on Jan. 23, 1812, and Feb. 7, 1812. The February earthquake centered near New Madrid, Mo., is believed to be the biggest of the three, based on newspaper accounts of damage to buildings, according to the United States Geological Survey. The quakes rang church bells 1,000 miles away in Boston, cracked sidewalks in Washington, D.C., and rattled china in the Colorado Rockies.
A letter written by Eliza Bryan of New Madrid describes what she experienced during those months of 1811-1812:
"We were visited by a violent shock of an earthquake, accompanied by a very awful noise resembling loud, distant thunder, but more hoarse and vibrating, which was followed in a few minutes by a complete saturation of the atmosphere with sulphurous vapor causing total darkness. The screams of the afrightened inhabitants running to and fro, not knowing where to go or what to do; the cries of the fowls and the beasts of every species; the cracking of trees falling, and the roaring of the Mississippi ... all formed a scene truly horrible ... The inhabitants fled in every direction to the country, supposing that there was less danger at a distance from, than near the river ... The earth was in continual agitation, visibly waving as a gentle sea."

Park Ranger Warren Douglas has felt three earthquakes
A newspaper report from that time period told about earthquake mishaps of the New Orleans, the first steamboat on the Mississippi River. She was on her maiden voyage, and the crew reported "mooring to an island only to awaken in the morning and find that the island had disappeared below the waters of the Mississippi River."
According to a report by the U.S. Geological Survey, "some of the most dramatic effects of the earthquakes occurred along rivers. Entire islands disappeared, banks caved into the rivers, and fissures opened and closed in the river beds ... New sections of river channel were formed and old channels cut off. Many boats were capsized and an unknown number of people were drowned ..."
At the time of the 1811-1812 earthquakes, the Reelfoot area was little more than a swampy, hardwood forest covered with bald cypress trees.
"Reelfoot Lake acted as an oxbow for the Mississippi River," Douglas said. "We didn't have a levee system then. When the river was naturally high in the winter time, it would flow through the swamp and kind of disperse like it does during floods now.
"What happened, when those earthquakes occurred, the land on the east side of the (Mississippi) river sank about 10 to 12 feet, and the trees and forest sank with it. Eyewitness accounts from New Madrid at that time said the Mississippi River ran backward ... But when you've got high water over here (at New Madrid) and a depression over here (in the Reelfoot area), the water running over fills the hole up. Well, to those folks, it looked like (the river) was running backward. It ran more sideways than backward, and it filled up the depression."
Due to the high water, Douglas said Reelfoot Lake probably covered close to 60,000 acres back then, stretching from Hickman, Ky., to Dyersburg.
"Over time, the floodwaters left, and we were left with what we have today, Reelfoot Lake," Douglas said.
The shakes continue
Research during the past 20 years has shown "that strong earthquakes in the central Mississippi Valley are not freak events but have occurred repeatedly in the geologic past." The first recorded earthquake in what is known as the New Madrid Seismic Zone occurred on Christmas Day, 1699. Since the area was sparsely populated, it is unknown how many deaths occurred during the first big quakes.The 1990 scare
"There had to be fatalities (in 1811-1812), but we don't know," said David Haggard, a park ranger the past 20 years at Reelfoot Lake State Park. "It was a time in history when they didn't keep records."
Researchers know that fatalities could be overwhelming when nature unleashes another round of magnitude 7 or 8 earthquakes on the New Madrid Seismic Zone, which includes metropolitan areas like Memphis and Saint Louis. It's just a matter of time.
There are already an average of about 200 smaller tremors along the New Madrid Seismic Zone each year. But Douglas has felt only three earthquakes.
"One of them, I was standing on the bank of a lake fishing," he said. "It did cause me to stumble. It was a (magnitude) 4.2 centered in Blytheville, Ark.
"Another one rattled the dishes and windows at our house. Another was back last February, one of the 4.0s we had. It woke me up. I thought it was thundering outside. I thought one of the kids was shaking the bed because they were scared of the thunderstorm. I raised up, and I didn't think anything about it. I came into work that day about two hours later and they said, 'Hey, we had a 4.1 earthquake this morning.' And I said, 'That's what that was.'"
Prior to Hurricane Katrina, the last big push for earthquake preparedness was triggered by a prediction of doom.Jackson tremors
New Mexico climatologist Iben Browning said there was a 50-50 chance of a major earthquake occurring along the New Madrid Fault about Dec. 2 or Dec. 3 of 1990.
As the date approached, some areas experienced panic. There was a run on bottled water at groceries, and some folks left town. When Dec. 3 arrived on a Monday, classes were dismissed at Lake County, Lauderdale County and Dyersburg City Schools.
"I was a junior in high school then," Douglas said. "That was a free day to go quail hunting or something if we wanted to. That's all we did that day. We weren't worried about an earthquake."
Neither was the scientific community, which studied Browning's theory based on the proximity and alignment of the sun and moon. Scientists said the theory was "about as reliable as putting a calendar on a dart board and tossing darts at dates."
Sure enough, while hundreds of media representatives, including The Jackson Sun, converged on New Madrid, Mo., that day, nothing fell but the temperature.
But the excitement had a positive side. It caused states and communities, including Jackson, to examine their emergency plans and conduct drills to be prepared.
The Jackson area occasionally feels a tremor but has experienced no serious damage.Visit jacksonsun.com and share your thoughts.
There were two significant reports in 2005. On May 1 at 7:37 a.m., a magnitude 4.1 earthquake occurred 15 miles west southwest of Blytheville, Ark. The USGS received 61 reports from Jackson residents who felt the quake.
And on June 2 last year at 6:35 a.m., a magnitude 4.0 earthquake occurred 10 miles north northwest of Dyersburg. The USGS received 63 reports from Jackson residents.
According to Associated Press reports, one of the strongest earthquakes in the region in the last century was a magnitude 5.4 on Nov. 9, 1968 in south-central Illinois. It was felt in 23 states, including Tennessee.
NOT to be confused with earthquakes elsewhere around the planet, this is something I have not seen before over such a wide area.
Did the sensor network undergo some kind of damage? Is there some kind of interference happening? Is this a REAL detection of low frequency vibrations occurring?
