Will USA be Destroyed by 2016?



No one can deny the fact that USA is the most powerful country in the world and is also the super power. It has several enemies but still it's biggest enemy  is hidden. This enemy is hidden underground. The enemy name is Earth-quake.

Most of the US states lies under fault lines and are constantly under extreme danger of severe earthquake. But following six states can be jolted anytime with earthquake of magnitude 8.0 and above. Among these fault lines some are capable of producing quakes bigger than the 1906 San Francisco quake, but because the time between major jolts is longer than in California, many people who live near these faults don’t even know they are there.
HAWAII ZONE: Hawaii is well known for its volcanic hazard, but the islands are also susceptible to major earthquakes such as a magnitude 7.9 quake in 1868 that killed 77 people.  Evidence of prehistoric quakes is hard to come by in Hawaii, making it especially difficult to guess when the next big one will strike.
The Hawaiian Island chain was formed by a massive plume of extra-hot magma rising through the molten mantle between Earth’s crust and core. The plume forced its way through the ocean crust, creating a volcano. As the Pacific plate slowly moved over the stationary plume, new volcanic islands were formed as older ones went dormant — the Big Island is where the magma is currently breaking through.
"All our earthquakes are ultimately associated with the processes that form the volcanoes," said earthquake seismologist Cecily Wolfe at the University of Hawaii at Manoa.
THE PACIFIC NORTHWEST ZONE: A much greater hazard, at least in terms of sheer magnitude, exists to the north of the San Andreas Fault where the ocean crust is being forced beneath the North American continent.

Known as the Cascadia Subduction Zone, this 680-mile long stretch of colliding land mass 50 miles offshore of Oregon, Washington state and southern British Columbia is capable of generating magnitude 9 earthquakes 30 times more powerful than the worst the San Andreas can dish out.

NEW MADRID ZONE: Tectonic plate boundaries are known for the most earthquakes in the world, where land masses are colliding or pushing past one another. But in the middle of the country lurks a geological enigma near New Madrid, Missouri, that has produced some of the largest quakes on record for the United States but has yet to be fully explained by scientists.
In 1811 and 1812, a swarm of at least three massive earthquakes struck near New Madrid, the largest of which exceeded a magnitude 8 and caused violent, damaging shaking in an area 10 times larger than did the 1906 earthquake. The quake was felt over an area of two million square miles — nearly two-thirds of the country.
SALT LAKE CITY ZONE: The forces that have built Utah’s incredibly scenic landscape are also the source of a very serious and potentially deadly seismic hazard. Running along the base of the western edge of the Rocky Mountains, the 240-mile Wasatch Fault lies underneath Salt Lake City and the state’s urban corridor, home to 1.6 million people.
Though the Wasatch Fault has not delivered a major quake since the Mormon settlers arrived in 1847, geologists have found evidence that it is capable of unleashing jolts as big as magnitude 7.5. It is one of the world’s longest "normal" faults, where the land on one side of the fault drops down relative to the other side during an earthquake. During prehistoric times, the fault slipped as much as 10 feet during a single quake.
ALASKA ZONE: The second-largest earthquake ever recorded struck Alaska’s Prince William Sound in 1964. The magnitude 9.2 quake killed 128 people, most by the resulting tsunami.
In some places, the ground was uplifted almost 38 feet, and in others it dropped more than seven feet. The tsunami reached heights of around 220 feet locally, and killed 11 people 1,650 miles away in Crescent City, California.
The "mega-thrust" quake was the product of the collision of two tectonic plates, the oceanic plate being forced beneath the continental plate. Those plates are still moving and accumulating stress that will eventually be released in another big quake. The geologic record shows gaps of 350 to 900 years between monster quakes, which would seem to put the Alaskan coast in the clear. According to these estimates America will have to bear a lot of earthquakes by 2015 end to mid of 2016.
Now if we add bit of toppings to above facts then situation become more worse. And that topping is that most of the country's nuclear reactors are also in seismic zone. Please see below picture:
There are currently 110 operational nuclear power plants in the country and 50% of them are in dangerous earthquake zones under the fault lines. So all the countries working on nuclear plants need to very carefully look for places away from earthquake fault lines.
