This guy states western part of the US will get hit by an earthquake within seven days. Can any one verify this?

Or have I become paranoid with the 175,000 toll?

However a month back there was something about a possible future quake in that same area posted at earthquake.usgs.gov on their earthquake info page.

Oh, and what is this reality you want to subject us to!? I object in the strongest!
It doesn't say what this person you found is saying is false, but rather that it hasn't hit mainstream earthquake sites yet if it isn't false.

I'll feel it if it happens...
:p
That said, the risk of a signifigant quake in New Madrid is large. in 1811 there was a quake that is considered the largest known quake to hit the continental US.
If another quake were to hit New Madrid today with the same magnitude, it could devistate St. Louis. While it is more than 150 miles away, the ground between the two locations is mostly soft river bottem that could quickly transmit the energy north.
[quote]In December, January and February of 1811-12, three great earthquakes, all having magnitudes estimated to be greater than eight on the Richter Scale, shook this region, altering the landscape dramatically. The earth was observed to roll in waves a few feet in height. When these swells burst, large fissures were formed. One family that lived on a short bend of the Pemiscot River in the Missouri bootheel found that the entire river had been diverted through one of these fissures, resulting in the point of land on which their well and smokehouse were located moving to the opposite bank. Caving banks, along with ground motion, created tsunami-like effects on the Mississippi; many boats were swamped, while others were "...cast high and dry upon the shores". Two waterfalls were formed; one upstream from New Madrid, the other downstream, causing the river to reverse its flow for several hours. An island in the river completely disappeared, taking with it a band of river pirates.
Large areas of land were uplifted while much land sank, draining existing lakes and creating others, such as Reelfoot Lake in northwest Tennessee. Sand blows erupted like geysers, spreading sand over large areas where it is still visible today, after many years of cultivation. These eruptions of sand and water were called sand volcanoes by observers.
The damage area for the 16 December 1811 New Madrid earthquake was 15 times as large as the area of similar damage for the magnitude 8.3 San Francisco earthquake of 1906. And the third of these great earthquakes, in February of 1812, is the largest known earthquake in the continental U.S. Only Alaska has had a larger one, the Great Alaska earthquake of 1964. [/quote]

[quote]Structure
The New Madrid Seismic Zone is made up of reactivated faults that formed when North America began to split or rift apart during the breakup of the supercontinent Rodinia in the Neoproterozoic Era (about 750 million years ago). The rift failed, but remained as a scar or zone of weakness. During the Mesozoic Era (about 200 million years ago), as the Atlantic Ocean was opening in the east, rifting was once again re-activated and intrusive igneous rocks were emplaced. But again the rifting failed and the continent remained intact, although with a significant zone of weakness. This rift is known as the Reelfoot Rift and coincides with the northernmost portion of the Mississippi embayment. Most of the seismicity is located from 5 to 25 km beneath the Earth's surface.[/quote]
So it's like Rhine valley in Europe:

Here's nice map showing well how much bigger area quake will affect when it happens there.

Here's also about that hoax.

BTW, If you ask me biggest hoax of all time is claimed intelligence of human specie.
So it will be just fine if I move to Northern Tennessee then...
Same ol, same ol...

Rock n' Roll!

What? Old?

Mmmmm Liquifaction.

Yep, and there is a lot of it between the bootheel of Missouri in St. Louis, where I live (though Memphis is in greater danger). I used to live in Columbia Missouri, which is about halfway between St. Louis & Kansas City. The danger of damage from a New Madrid an earthquake there is much more limited due to some large deposites of granite and other dense rock between.

Isn't it Ireland that has the oldest exposed rocks at something like 3.64 Billion?
Can't remember. It's been a while since I saw the special on the learning channel about it.
:)
I know China has some very old sea beds exposed in upright colums too...
