San Andreas Won't be the Next Big One

[Wry Catcher]

There are two faults in the US that are far more dangerous than the San Andreas. One is the Cascadia Subduction and the other the New Madrid. Both are due. Interesting times when either lets go.

The Caldera under Yellowstone NP has been labeled a Supervolcano and if or when it erupts the world will suffer a cataclysmal event. New Madrid might change the course of the Mississippi, but the BIG ONE would change the course of history.

Sure, that could be a problem, but what's that compared to manmade global warming

The Madrid fault and Yellowstone are opposing sides of the North American Craton. Oklahoma at the bottom of the Craton edge is showing signs of massive strain. IF the Madrid side should move the potential for a YS eruption increases by almost 100%. The last movement of the NM area resulted in hydro-thermal eruptions at YS in the early 1800's leveling the trees for hundreds of miles.

Lack of adequate earthquake building codes in those states will be the biggest part of the disaster.

A minor tremor in VA cracked the Washington obelisk and made my office on 42nd and Lexington sway back and forth like a wave pasding under a small boat, so yeah, we're screwed

Ah yes, a fluid wave... That area is like a bowl of jello. the ripples in the pond will tear buildings in two.

Yep, we had a minor one some years ago, shook dishes off the shelf in North Alabama.

Ah, but Crusader, requiring building to be updated to reasonable earthquake codes is government regulation, and we cannot have that.

Silly Billy, would you care to link some evidence of your claim for us? No mention of such in the USGS article;

Even if physically possible, do you have any idea at all of the cost involved in the retrofit?

 

[Old Rocks]

What is human life worth, Crusader? That is what the price of building collapses are measured in.

 

[IanC]

Should we ban people from living in trailer homes in areas that are prone to tornadoes? What is a life worth?

 

[CrusaderFrank]

Are we retrofitting ALL buildings, office, retail, single family homes? How large a shake are we defending against? Are you recommending steel reinforcement of every single family home in America?

Why not outfit everyone with a Bubble too?

Old Rocks doesn't understand the concept of Risk analysis or Management.

By his logic all homes in Florida should be designed for a snow load of 1 to 2 feet of coverage by wet snow.

LOL The subject is the area where the New Madrid Quake was most intensive. And that quake was a good deal more powerful than the 1906 California quake. The shaking was felt clear to the Atlantic coast. But not to worry, you tell all the nearest of kin of those caught by unreinforced buildings in the area that is just wasn't worth it to protect those lives.

All East coast earthquakes propagate further due to the conditions of the plate and the crust in the area. It has nothing to do with strength, as any quake is felt further away due to these mechanics.

Most new buildings ARE built with seismic codes in mind, but ones of lesser fortitude than California due to the lower overall risk.

So you want to steel reinforce every building in the entire southeastern USA, is that correct?

 

[CrusaderFrank]

What about asteroid insurance?

In areas of seismic activity, where the activity may possibly one day be very severe, but hasn't had a major quake in 200 years, overbuilding to protect against a potential one is not arguable as a good use of resources.

In an area of frequent severe activity, I'd agree with you. Not for the New Madrid though for anything under 3 stories.

Ask any abortion advocate. Life's cheap.

Lets review..

It's happened before 1811-1812

The geologic record of pre-1811 earthquakes reveals that the New Madrid seismic zone has repeatedly produced sequences of major earthquakes, including several of magnitude 7 to 8, over the past 4,500 years.

Three Main Shocks

1. December 16, 1811 - Magnitude ~7.5
2. January 23, 1812 - Magnitude ~ 7.3
3. February 7, 1812 - Magnitude ~ 7.5

Historic Earthquakes

Now I wonder if your capable of reading the journals of Lewis and Clark? or the journal of John Coulter who was in the region at that time and witnessed the trees that were fell by the hydro-thermal explosion of January 24, 1812. Coulter's journal states "the trees were fell as far as the eye could see".

Many say these were just coincidences but there is question to the motion of the the tectonic plate being the cause of the event.

Coincidence or cause/effect?

John Colter: The First Mountain Man

Although the details of John Colter’s extraordinary life and achievements are known primarily from the accounts of others (Colter kept no journals), enough is known to say with confidence that John Colter — hunter, trapper, explorer, and Indian fighter extraordinaire — deserves to be known as the first mountain man, the earliest in a lineage of intrepid men who explored the West before the Mexican War, the great Westward migrations, the cattlemen, the stagecoaches, and the railroad later in the century transformed the region. In all the annals of the American frontier, Colter’s feats of sheer physical endurance have seldom been equalled. He probably achieved more “firsts” in Western exploration than any other mountain man except Jedediah Smith — who traveled with much larger, better-equipped companies.

Silly Billy, perhaps a link to some verifiable source would prevent all from assuming once again you pulled a silly story out of your ass.
