New Madrid Fault And Arkansas Earthquakes Spur Fears In The Midwest

Recently, we have seen a dramatic increase in sales of SurvivalOutpost products to customers in the Midwest. The reason for this increase in sales would seem intuitive -- Midwestern states have been getting routinely hammered by the epic winter snows of 2011; and indeed, this is partially the case. However, after interviewing a handful of our customers from the Midwest, we made a new and rather sobering discovery -- many of these customers are becoming increasingly worried about the New Madrid Seismic Zone, an increase in Arkansas earthquakes, and the strange (and poorly explained) deaths of thousands of birds and fish in the region, and they are planning for the worst.

When most people in the United States think of Seismic Zones, they generally think of California. With the San Andreas Fault slicing more than 800 miles through California - a massive fissure separating the North Atlantic and Pacific plates - and a history of attention-grabbing tremors to remind us of it's volatility, California generally wins the prize as the earthquake high-risk zone of note. But it may surprise you to learn that there is another active seismic zone in the United States, one that is responsible for this country's four largest earthquakes ever, with magnitudes exceeding 8.0, and it isn't on the west coast.

It's in the Midwest.

Specifically, this active region, called the New Madrid Fault, lurks under a four-state area including Arkansas, Missouri, Tennessee, and Kentucky, but has the potential to affect a region that is far greater. In fact, in a cluster of earthquakes that began in December of 1811 and continued into February 1812, referred to as the '1811-1812 Earthquake Series' and one of the worst in this country's history, the New Madrid Fault shook so hard that church bells on the east coast started ringing. People as far away as New York City and Boston could feel the rumbling. One tremor, located almost exactly under the spot where Memphis is found today, shook so hard the river appeared to flow upstream. As Wiki states,

"The future location of Memphis, Tennessee was shaken at Mercalli level nine intensity. Local uplifts of the ground and water waves moving upstream gave the illusion that the river was flowing upstream. At New Madrid, trees were knocked down and riverbanks collapsed. This event shook windows and furniture in Washington, D.C., rang bells in Richmond, Virginia, sloshed well water and shook houses in Charleston, South Carolina, and knocked plaster off of houses in Columbia, South Carolina. In Jefferson, Indiana, furniture moved and in Lebanon, Ohio, residents fled their homes."

A similar earthquake today would be devastating, and would likely result in thousands of deaths, billions of dollars of damage to structures and critical infrastructure, and the displacement of millions of people. Indeed, it would be an earthquake event of biblical proportions. Which is why, of course, people that live in this region of the country are becoming increasingly concerned.

It doesn't help that recent earthquakes have rattled the ground and nerves of Arkansans, plus the unexplained fish and bird deaths which have pockmarked the same region have people all-a-jitter. All of this has understandably sparked wild and fanciful, and in some cases outlandish speculation as to what might be really going on. From HAARP testing, to a 2012 pole shift, to oil industry gas 'fracking' gone amok, to biblical End Times geophysical volatility, the wild-eyed conspiratorial musings about the New Madrid fault zone would be downright hilarious were it not for one small exception...and that exception is that it appears as if FEMA has taken a sudden interest in the New Madrid Fault and is actively planning for a potentially devastating event.

In late January 2011, FEMA distributed a series of RFIs (Request For Information) to potential vendors to provide food, blankets, fuel and other resources in the event of a New Madrid earthquake. The language in the request is sobering, "The purpose of this Request for Information is to identify sources of supply for meals in support of disaster relief efforts based on a catastrophic disaster event within the New Madrid Fault System for a survivor population of 7M to be utilized for the sustainment of life during a 10-day period of operations." FEMA is essentially soliciting a vendor (or vendors) to provide in excess of 14 million meals for a New Madrid event, for ten days.
That's right -- 140 million meals.

Conspiracy theories aside, the timing of these requests are strangely coincident with the earthquakes and widespread bird and fish kill in the region, which, not surprisingly, has caused this thing to go viral. And even a rational mind has to stop and meditate on the timing of these requests.

Keep in mind, FEMA is paid to look for potential risks and then take appropriate steps to mitigate the associated hazards. Preparing for the low-probability, high-consequence event is what they do (or at least what they should be doing). So, taking steps to prepare for a New Madrid event seems both logical and responsible. But...the question nevertheless begs, why now? What changed in 2011 to cause FEMA to suddenly take the New Madrid seriously, given that the hazard has been there for hundreds of years?

Is there a relationship between the dramatic increase in seismic events in northern Arkansas, the bizarre die off of birds and fish in the same area, and the sudden interest in the New Madrid Fault zone by FEMA?

Is all this coincidence or conspiracy?

And that gnawing uncertainty appears to be motivating a lot of people into action.

Whether there is anything to the timing or not, it is always best to be prepared.

Cat Behavior - Cat's Sixth Sense

For many years stories of cats with strange abilities to foretell natural disaster or weather changes have abounded. Most reports concern cats showing strange behaviors before storms, volcano eruptions, earthquake or even before less natural phenomena such as air raids. (Many households with a cat in World War II soon realized they could regard puss as a reliable early-warning system as it became agitated before sirens went off) Often stories involve a mother cat moving her kittens from an area or house which later is devastated by flood, landslide or lava to a safer refuge; or a cat trapped within four walls desperately to get out. Reports of such instances of forewarning, as displayed by many cats before the 1979 California earthquake, are now taken so seriously in America that scientists in seismology there are studying the behavior of over 200 species of animals with the help of 10,000 volunteer observers. If these observers notice anything peculiar in the animal's behavior, they have to dial a hotline to ythe earthquake scientists. This is also done in China and in 1975, acting on the behavior of cats and other animals, Haicheng was evacuated twenty-four hours before a huge earthquake devastated the area. No doubt the cats had already taken to the hills. And, let's face it, if you live in a region likely to suffer from quakes, all forewarnings are greatly received.

There are several theories as to how cats seem to be able to predict these happenings. During rainstorms, enormous amounts of electricity are discharged into the clouds and create electromagnetic waves that spread through the atmosphere for hundreds of miles. The air becomes charged with positive ions which thought to influence the concentration of certain chemicals in the brain. As a result some people suffer headache before thunder. The cats may be many times sensitive to these ions, and the changes within its brain cause its mood and behavior to alter dramatically. They may also have the ability to use the Jacobson's organ to sample molecules in very dilute concentrations in the air and get a forewarning of more violent changes to come - such as when a volcano has begun to smoke, and so releases the gases within it, but has given no great outward sign of eruption. Some cats are said to rub their ears before heavy rain, responding, perhaps, to pressure changes that agitate the sensitive inner ear.

The sensitivity of the cat's feet and whiskers to vibration may mean that it can sense the tiny tremors which precede an earthquake. If we take into account this awareness of vibrations, the ability of the cat to hear ultrasonic sounds to detect magnetic changes, then a storm or earthquake may be as obvious to a cat as an air-raid siren is to us, and might well be detected hours before we humans become aware of it in its much less subtle form.

While prediction of earthquakes or other physical phenomena can perhaps be explained by modern science, there remain several vexed questions concerning a 'sixth sense' in cats. There are many reports of cats that anticipate the return of their owners after a long absence and without obvious warnings. There are also many, many stories, some corroborated by evidence rather than just anecdotal accounts, of cats traveling hundreds of miles after being left behind on holiday on holiday or returning to their old home after a move. Cats do appear to have remarkable navigational powers, perhaps thanks to an in-built magnetic sensitivity which gives them the same homing ability as is found in pigeons. They also have an amazingly accurate 'internal clock' and will welcome the kids home from school at the same time each day or wait by the wait by the food bowl at the right hour every evening.

Stranger still are tales of cats which have left home to find their owners at great distances away, in places that they have never been to before. One such story is of a cat whose owners were due to more to a new house 200 miles away. On the day of the move the cat somehow got left behind, but it turned up later at the new house! How these cats can even begin to figure out the right direction to take, let alone pinpoint the location of a house so very far away is a complete mystery. But this is by no means a unique story. There are sufficient reports of similar strange happenings to make us want to find out more about just how these cats are able to do it.

Psychic Predictions 2012: Social Unrest and Flood Prediction

Psychic predictions in 2012 are a hot topic. The year so far has been one of major global social unrest in many counties the like of which we have not seen before. Flood and earthquake disasters are creating more devastation with destruction of city infrastructure. Here we use the psychic art of prediction to see what the future holds for our international global village:

1. The euro falls sharply and it drops to an all time low. It falls to one third of its January 2011 value. The broke economies of Spain, Greece, and Portugal drag the currency down the tubes.

The other factor that contributes to its decline is massive conflict on the continent of Africa. Thousands of refugees migrate to European shores seeking safety and well being. Riots begin to spread from African countries to Europe further weakening the financial system. The economies of Germany and France are strong yet they will be worn down constantly by unexpected negative surprises. Problems with food distribution in major cities, public riots, and the looting of residential homes are foreseen to cause major headaches.

2. Oil doubles in price. Solar flares cause satellites to malfunction and this creates an open gateway for minor dictators to reign supreme on the battlefield. The military dictators will send their soldiers to hijack oil tankers for ransom and to trade. The result is the cost of oil transportation costs skyrocket and leaves the consumer with a bigger price tag.

3. Radiation enters the water supply of many countries. The 2012 psychic predictions state that the impact of flood disasters with their tsunami force of impact destroys several nuclear reactors. Plutonium leaks into the drinking water of many countries. Drinking water that is polluted by radiation causes a slow death. Fresh drinking water will be the new commodity of trade in the future because it will be so scarce.

4. A large comet enters the earth's atmosphere and smashes into the pacific ocean. The impact of the comet causes flooding of the California coastline.

5. Floods will be a major problem for many countries in the year of 2012. This will be good for ship and boat manufacturers as water travel becomes more common and the demand for this service will increase.

Flood and disaster predictions entered a new phase beginning with the natural earthquake disaster of Haiti. It was a sign from nature of things to come and many psychics viewed it as a forewarning to pay heed to such famous recorded predictions of Nostradamus and Edgar Cayce. It was the start of a fierce and destructive form of natural catastrophe which ushered in a new age of cataclysm.

6. Large parts of Russia are flooded due to the melting of the polar ice caps and a raise in sea level. This will take Russia and many other weather forecasters by surprise. It will be a fact the rapid increase in sea level will shock many.

7. A trend will emerge and lots of people will move from cities and urban suburbs to smaller and more communal villages.

In the final analysis the psychic 2012 predictions show the immediate future full of natural disasters, floods, and social unrest. But don't worry mankind survives it all! There are psychics who have already seen the triumph of humanity with their clairvoyant sight.

California Earthquake - Psychic Prediction

Most of us who live in Southern California are aware that a major earthquake is bound to occur within the next 10 years. We look toward the scientist to inform and prepare us for those dreaded earth quake strikes.

I would rather not talk about the "big one" that has been expected to occur for decades because these sort of predictions tend to ignite deeper fears in our already fearful position in these earthquake ridden regions. We have heard and read about the big quake that is bound to happen so much that we have become desensitized.

There are dozens of meanings one can perceive from a psychic vision. This is why they need to be considered hypothetical in nature, worthy of study and reference but not taken as verifiable. However, psychic visions of an apocalyptic earthquake in southern California are being forecasted by reputable psychics much too often to ignore and remind people of the very real seismic dangers in the region.

Although I predicted a sizeable earthquake this year in my 2009 Psychic Predictions, the big one is about a year or two away. I keep seeing the year 2011 like a pulsating animation within visions of major earth shifts in my home state of California. Dates perceived in months or years could be argued to have limited value in forecasting a time because we psychics move our consciousness in large spans of time and cover broad areas of locations and events. On the other hand, the numbers 2011 is a significant part of the psychic vision.

Earthquake ridden fault zones are located throughout California but the areas in my vision are moving in the southern regions of California, from the outskirts of San Diego, the deserts, off shore Long Beach, Los Angeles, San Bernardino and Riverside Counties. The magnitude does not seem as significant as the amount of confusion in the collapse and destruction of buildings, structures, moving vehicles and machinery.

Earthquake preparedness may be mundane topic every year but how many of us are prepared? Contact the national CDC for information on how to survive in earthquakes and disasters, the more you educate yourself, the better prepared you become and you just might save the life of someone else as well.

Is It Easier To Predict Volcanoes Or Earthquakes?

It seems that in recent years some of the most severe hazards have taken place. Their enormous destructiveness goes hand in hand with the suffering of the people concerned. Many of us will ask ourselves why such disasters could not be prevented in times of modern technology and high scientific know how. But like weather, volcanoes or earthquakes cannot be influenced by the human intelligence. Life would not be life if we could control everything, even if it is difficult to comprehend why these terrible things do happen.

I have written this article to explain a little about the nature of volcanoes and earthquakes.

Especially volcanic eruptions and earthquakes are devastating natural hazards which are both difficult to predict and difficult to respond to.

However, examples like Montserrat, Mount St. Helens, Heimaey, the San Francisco earthquake and the Mexican earthquake illustrate the differences in terms of predicting and responding to these hazards.

Volcanic eruptions are easier to predict than earthquakes, as minor earthquakes are often the first 'sign' of a following volcanic eruption. The example of Mount St. Helens underlines this, as first signals of a coming volcanic eruption could be noticed already three months before the actual eruption. These signals can be either minor earthquakes or even gas production in a volcano shows that it is 'active.'

Earthquakes are harder to predict as they occur suddenly without any warning or with short notice. However both earthquakes and volcanoes can be monitored and observed by seismographs, tilt meters, lasers, GPS and observation. Furthermore some animals like catfishes can be used to predict them as they are very sensitive. It is also possible to create hazard maps as prediction for volcanic eruptions. These are based on previous eruptions and close observations.

The example of Heimaey in Iceland shows that volcanoes can also occur unexpectedly. It erupted without any previous signs on January 23rd 1973. In this case there were only 24 hours of minor tremors before a 400 metre fissure opened up to pour out lava. The Heimaey is only one example where a volcanic eruption occurred without previous warning. Other examples like Mount St. Helens and Montserrat show that volcanic eruptions are usually easy to predict. Mount St. Helens for example resulted in the largest landslide in recorded history with a speed of 70 to 150 miles per hour. But due to great preparedness only 57 people died. This shows that early warning results in easier and more accurate prediction.

As a general rule, it can be said that earthquakes are more difficult to predict than volcanoes as they occur without any warning.

Earthquake Risks in California

California Earthquakes

California earthquakes are developed by movement of huge blocks of the earth's crust; the Pacific Plate and the North American Plate. The Pacific Plate is moving northwest, scraping horizontally past the North American Plate at a rate of about 2 inches per year. About two-thirds of this movement occurs on the San Andreas fault and some other parallel faults. Over time, these faults produce about half of the significant earthquakes of the region, as well as many minor earthquakes.

Earthquake Prediction in California

Earthquakes occur suddenly without warning, during any season, and at any time of day or night. Sponsored by the United States Geological Survey (USGS), California Geological Survey (CGS), and Southern California Earthquake Center (SCEC); the 2007 Working Group on California Earthquake Probabilities, released the Uniform California Earthquake Forecast (UCERF). It states that California has 99.7% probability of having a moment magnitude Mw = 6.7 earthquake (same as Northridge event) during the next 30 years. The southern segment of San Andreas fault has the highest probability of generating such an earthquake scenario in southern California with a 67% chance of striking the greater Los Angeles area, while Hayward fault is the most likely earthquake source in northern California with a 63% chance of striking the San Francisco bay area. Larger earthquakes are less likely during the same time frame; 94% probability of Mw = 7.0 event, 46% probability of Mw = 7.5 event, and 4.5% probability of Mw = 8.0 event. For all magnitudes, the earthquake is more likely to occur in southern California than in northern California.

Hazards Associated with California Earthquakes

  1. Liquefaction susceptibility where partially saturated soil deposits may completely lose cohesion during prolonged shaking, behaves like a liquid, and loses their ability to support structures. The highest hazard is in low-lying areas where there are loose, sandy soils or poorly compacted artificial fill. A liquefied sand layer can shoot to the surface through cracks, forming a sand-blow, and depositing sand on the ground. This results in permanent ground deformations such as lateral spreading and settlement, both of which increase the likelihood of damage to buildings and infrastructure. Areas prone to liquefaction include, but not limited to, the southern Coachella valley and the upper Santa Ana river basin in southern California; San Francisco bay area, northwestern Alameda county, and northern Santa Clara valley in northern California as predicted by the USGS.
  2. Landslide susceptibility where steep sloping areas underlain by loose or soft rock are most susceptible to earthquake-induced landslides, damaging buildings and other structures. Areas prone to landslides include, but not limited to, eastern San Gabriel mountains.
  3. Surface fault rupture where shallow faults can breakthrough the ground surface as they displace against each other during an earthquake causing severe damage to building and infrastructures.
  4. Fires where earthquakes in urban areas are often followed by destructive fires because of gas lines break and electrical shorts that may quickly spread due to clogged roads and collapsed bridges that prevent firefighter access, or damaged water tanks that limit water for firefighting. Without fires, the casualty and economic losses would be halved.
  5. Tsunamis where major earthquakes occurring in the Pacific Ocean may displace the ocean floor, generating tsunami that could affect the West Coast.

Expected Economic Losses focusing on Northern California

There is a 62% probability that at least one earthquake of Mw = 6.7 or greater will occur in the San Francisco bay area before 2032. Hayward fault has the highest probability of 27% of generating such earthquake event, while the northern segment of San Andreas fault has a probability of 21%, the Calaveras fault of 11%, and the San Gregorio fault of 10%. It is well-known that soft soils in San Francisco bay area would amplify and prolong the shaking even at great distances from the ruptured fault. Consequently, a repeat of the 1868 Hayward earthquake is expected to cause significant loss of life and extensive damage to homes, businesses, transportation systems and utilities. Several hundred thousand people are likely to be homeless after the earthquake. Economic losses exceeding $120 billion is expected. These losses include damage to buildings and contents, business interruption, and living expenses, with more than 90% of both residential and commercial losses being uninsured.

Expected Economic Losses Focusing on Southern California

A 2008 comprehensive study, known as the ShakeOut scenario earthquake, by the USGS and CGS of a hypothetical Mw = 7.8 earthquake rupturing the southernmost 200 miles of San Andreas fault has been performed. The fault rupture will produce more than 100 seconds of shaking throughout southern California. The event initiates from the epicenter at the Salton Sea producing very strong shaking along the fault as it ruptures until it ends near Lake Hughes. Soil conditions at sites along the fault will generally tend to amplify earthquake shaking. Deep soils in Los Angeles sedimentary basin would generate persistent shaking as the seismic waves are trapped and reverberate. The intensity of shaking will also be strong in San Bernardino valley, in areas prone to landslides mainly in the eastern San Gabriel Mountains, and in areas susceptible to significant liquefaction mainly in the southern Coachella valley where the two conditions of liquefaction applies; strong shaking and a high ground-water table. However, localized liquefaction is likely to occur in the upper Santa Ana and Santa Clara river basins. In areas of strong shaking and liquefaction, the ground will shift violently back and forth; collapsing thousands of older buildings, shoving houses off foundations, and sending unsecured furniture and objects flying. Such an earthquake event will cause some 1,800 deaths and 53,000 injuries. Fires are very likely to occur. The estimated economic losses total $213 billion due to earthquake shaking and its consequences specifically fires.

Get Ready to ShakeOut

You should participate in the annual Great California ShakeOut Earthquake Drill. You can register at the ShakeOut web site now for the 2010 ShakeOut Drill on October 21 at 10:21 a.m.! It is a great opportunity to learn how to protect yourself and your family during earthquakes, and to get prepared. More than 6.9 million Californians participated in the second annual earthquake drill in 2009. They were reminded to maintain their earthquake preparedness plan by preparing a personal survival kit for each family member and a household emergency kit, and to stockpile emergency food and water for 1-2 weeks to be prepared for the next inevitable earthquake. The magnitude 7.0 Haiti earthquake demonstrates the necessity of earthquake preparedness for anyone living in an active seismic region.

Interesting Fact on Earthquake Insurance in California

Homeowners insurance does not provide coverage for earthquake damage to your home. It is surprising to know that 33% of homes were covered by earthquake insurance in 1996 when the devastating 1994 Northridge earthquake was still fresh in people's minds, but in 2006 just 12% of homes maintained coverage, according to California Department of Insurance. Californians living in older homes should re-reconsider buying earthquake insurance as an effective way to manage potential costs of future inevitable earthquakes, especially after the 2010 Haiti earthquake.

Concluding Remarks

The 2010 Haiti earthquake is a wake up call for Californians to develop, update, or maintain their own earthquake preparedness plans. If you live within 15 miles of an active seismic fault and/or liquefiable area, you should re-consider retrofitting your home and mitigating its contents to protect yourself and your family. The benefits of seismic retrofitting and mitigation go well beyond being simply reducing financial losses. It will make your home safer and help in returning your family much more quickly back to their normal life style. In addition, re-considering earthquake insurance would help in managing potential costs of future earthquakes. Finally, develop an earthquake preparedness plan that includes maintaining emergency food and water for 1-2 weeks along with personal survival kits and a household emergency kit.
