New Madrid Fault Quake Zone Coming To Life?



Largest earthquake in 35 years hits Arkansas, March 1, 2011 (see second article below)




Is the New Madrid Fault Earthquake Zone Coming To Life?

Published January 6, 2011

What in the world is happening in the middle of the United States right now? Thousands of birds are falling dead from the skies, tens of thousands of fish are washing up on shore dead, earthquakes are popping up in weird and unexpected places and people are starting to get really freaked out about all of this. Well, one theory is that the New Madrid fault zone is coming to life. The New Madrid fault zone is six times bigger than the San Andreas fault zone in California and it covers portions of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi. The biggest earthquakes in the history of the United States were caused by the New Madrid fault. Now there are fears that the New Madrid fault zone could be coming to life again, and if a "killer earthquake" does strike it could change all of our lives forever.
So exactly what events have happened recently that are causing people to take a close look at the New Madrid fault zone? Well, just consider the following examples of things that have been popping up in the news lately....
  • According to the U.S. Geological Survey, more than 500 measurable earthquakes have been recorded in central Arkansas just since September.

  • A magnitude-3.8 earthquake that shook north-central Indiana on December 30th is being called "unprecedented." It was strong enough to actually cause cracks along the ground and it was felt in portions of Ohio, Illinois, Wisconsin and Kentucky.
  • More than 3,000 red-wing blackbirds fell out of the sky dead in the Arkansas town of Beebe on New Year's Eve.
  • Large numbers of dead birds were also found in Kentucky right around Christmas.
  • Approximately 500 dead blackbirds and starlings were also recently discovered in Pointe Coupee Parish, Louisiana.
  • Approximately 100,000 fish washed up dead on the shores of the Arkansas River just last week.
So could all of these things have some other very simple explanation?
Possibly.

But the fact that they all happened in or around the New Madrid fault zone is starting to raise some eyebrows.

About 200 years ago, in 1811 and 1812, there were four earthquakes that were so powerful in the area of the New Madrid fault zone that they are still talked about today. All four of the quakes were estimated to have been magnitude-7.0 or greater. It is said that those earthquakes opened deep fissures in the ground, caused the Mississippi River to run backwards and that they were felt as far away as Boston.

The last major earthquake to hit the region was a 5.4-magnitude quake that struck the town of Dale, Illinois in 1968. Things have been strangely quiet in the region since then until recently.
If a true "killer earthquake" struck along the New Madrid fault zone today, cities such as St. Louis, Missouri and Memphis, Tennessee could potentially be completely destroyed.
Unfortunately, this is not an exaggeration.
The following video describes just how incredibly powerful the earthquakes along the New Madrid fault in 1811 and 1812 actually were....



So could such a thing happen today?
Well, that is exactly what many seismologists now fear. The following video news report from ABC News explains why so many scientists are so concerned about the New Madrid fault zone....
_________________________________________________



One interesting theory is that the "oil volcano" unleashed by the BP oil spill in 2010 may have sparked renewed seismic activity in that part of the world.


Jack M. Reed, a retired Texaco geologist-geophysicist, has been carefully studying the geology of the Gulf of Mexico for over 40 years. Reed is convinced that the Gulf of Mexico is currently tectonically active, and that the Gulf of Mexico is the source for most seismic activity along the New Madrid fault.

According to Reed, there is substantial evidence that the New Madrid fault zone is directly connected to "deeply buried tectonics" in the Gulf of Mexico....
"This entire zone through the United States is suffering some type of tectonic activity that I believe is tied to the deeply buried tectonics in the Gulf of Mexico."
So did BP disturb those "deeply buried tectonics" by drilling such a deep well and unleashing all that oil that flowed into the Gulf of Mexico?

Let's hope not.

If a truly historic earthquake did strike along the New Madrid fault the amount of damage that could be done to surrounding states such as Illinois, Kentucky, Mississippi, Indiana, Alabama, Missouri, Arkansas and Tennessee could potentially be unimaginable.

Jeremy Heidt of the Tennessee Emergency Management Agency says that life in the region would be instantly transformed in the event of a major earthquake along the New Madrid fault....
"All communications would be out. All air travel would be out as the FAA air control would go down. All rail travel would fail. Ports would shut down; oil and natural gas pipelines could be off line."
According to a recent study by the University of Illinois, a 7.7-magnitude earthquake along the New Madrid fault would leave 3,500 people dead, more than 80,000 injured and more than 7 million homeless.


So what would happen if an 8.0 earthquake struck?
Or an 8.5?
Or a 9.0?
Remember, an 8.7-magnitude earthquake would be ten times worse than a 7.7-magnitude earthquake.

There are even some who believe that if a powerful enough earthquake hit the New Madrid fault someday it could potentially alter the surrounding geography enough that it could actually create a new major body of water in the middle of the United States.

So, no, it is not just California that needs to worry about "the Big One."

Right now seismic activity has been dramatically increasing all over the globe. Just think of the unprecedented number of volcanic eruptions that we have seen over the past year. Major earthquakes have been popping up all along the "Ring of Fire." Just over the past couple of days a magnitude-7.1 earthquake hit central Chile and a magnitude-7.0 earthquake struck northern Argentina.

So to think that "it can't happen" in the United States is just being totally naive.

Let us hope and pray that a devastating earthquake does not hit the New Madrid fault any time soon, because such an event could completely wipe out our economy. The U.S. economy is already teetering on the brink of disaster, and all it would take is one major blow to bring the entire house of cards crashing down.

Just remember what happened in Haiti. A magnitude-7.0 earthquake killed 230,000 people and caused such horrific devastation that it is still hard to even try to put it into words. Let us hope and pray that nothing like that happens in any U.S. city any time soon.

Largest earthquake in 35 years hits Arkansas

By SARAH EDDINGTON, Associated Press Sarah Eddington, Associated Press Tue Mar 1, 12:07 am ET


GREENBRIER, Ark. – The central Arkansas town of Greenbrier has been plagued for months by hundreds of small earthquakes, and after being woken up by the largest quake to hit the state in 35 years, residents said Monday they're unsettled by the increasing severity and lack of warning.

The U.S. Geological Survey recorded the quake at 11 p.m. Sunday, centered just northeast of Greenbrier, about 40 miles north of Little Rock. It was the largest of more than 800 quakes to strike the area since September in what is now being called the Guy-Greenbrier earthquake swarm.

The activity has garnered national attention and researchers are studying whether there's a possible connection to the region's natural gas drilling industry. The earthquake activity varies each week, though as many as nearly two dozen small quakes have occurred in a day.

"You don't know what to expect. It's unnerving," said Corinne Tarkington, an employee at a local flower and gift shop. "I woke up last night to the sound of my house shaking."

What woke Tarkington was a magnitude 4.7 earthquake that was also felt in Oklahoma, Missouri, Tennessee and Mississippi. No injuries or major damage have been reported, but the escalation in the severity of quakes in and around the small north-central Arkansas town has many residents on edge. Some said they're seeing gradual damage to their homes, such as cracks in walls and driveways.
"We probably had 40 to 50 calls last night," Greenbrier police Sgt. Rick Woody said, noting that the tone of the calls had changed. After pervious quakes, most callers simply wanted to find out if a loud noise they'd heard was an earthquake, he said.

"The fear had calmed down until last night," Woody said Monday. "People's biggest concerns (now) are whether or not these earthquakes are going to get any bigger."

Scott Ausbrooks, seismologist for the Arkansas Geological Survey, said Sunday's record quake was at the "max end" of what scientists expect to happen, basing that judgment on this swarm and others in the past. It's possible that a quake ranging from magnitude 5.0 to 5.5 could occur, but anything greater than that is highly unlikely, he said.
Ausbrooks said he plans to hold a town hall meeting in Greenbrier next month to address people's concerns.

"This quake actually scared folks," he said. "It lasted longer than a lot of the others did."

Ausbrooks said scientists continue to study whether there may be a connection between the earthquakes and local injection wells, where the natural gas industry pumps waste water that can no longer be used by drillers for hydraulic fracturing. Fracturing, or "fracking," involves injecting pressurized water to create fractures deep in the ground to help free the gas.

Geologists don't believe the fracturing is the problem, but possibly the injection wells.

A major source of the state's natural gas is the Fayetteville Shale, an organically-rich rock formation in north-central Arkansas. A six-month moratorium was established in January on new injection wells in the area to allow time to study the relationship — if any — between the wells and the earthquakes.

In Greenbrier, many residents are starting to notice gradual damage. Tarkington said her house has started to show cracks in ceilings and walls.

"You can see the wear and tear on our houses," she said. "I wish they'd go away."

Taylor Farrell, 29, a Greenbrier resident and employee at a local flea market, said a large crack formed in her driveway several months ago, and as the earthquakes continue, the crack has spread into her garage.

She said she and her husband had removed everything from the walls of their house, including family photos and television sets, because many photos had fallen in recent quakes.

"Other than that, there's really not much more you can do," she said.
 "It's Mother Earth. It's going to do what it's going to do. All we can do is wait for the big one and hope and pray it doesn't happen."
