Deep 'scars' from ancient geological events play role in current earthquakes

A proposed perennial plate tectonic map. Present-day plate boundaries (white lines), with hidden ancient plate boundaries that may reactivate to control plate tectonics (yellow lines). Regions where mantle lithosphere heterogeneities have been located are given by yellow crosses.

Well, you see, if the erf wasn’t getting sooooooooo hot and expanding, all these erf quakes could be avoided. Right?

[Robert A Cook PE]

No surprises there.

The New Madrid quakes and a long series of very low intensity quakes across the US show up on those two lines crossing the middle of the US.

This takes me to the hard to explain uplift of the the remarkably stable plate region of the Colorado Plateau (you can read a lot of history in the walls of the Grand Canyon) and the Basin and Range Provence which both of which rose two or more kilometers in elivation. What would cause the Colorado Plateau to uplift so far after accumulating sediments and occasional volcanics for some 600 million years.

This article might lead to some answers and a lot more questions.

A rather rough map of the orogenies (Major plate stresses and mountain building in the borders of the continental USA.

Fracking! OH-NOOOOO!

[sagar]

Just wait. These gubmint academics will find a way to link fracking and the ancient geological scars, somehow.

[cotton]

I kind of like Dr.
Walt Brown’s hydroplane theory to explain the uplift and many other things.

[Inyo-Mono]

As I'm sure you know, John McPhee's Basin and Range is an excellent read on the subject.

Whole lotta shakin’...

Our egg is cracked.

You’ll never hear about this in the MSM unless it can somehow be connected to LGBT “rights”.

Bush’s fault

[JimSEA]

You can take his book and wander through the peaks of the Ruby Mountains with its granite and diabase porphyry as a guide if I recall. Poet and technical journalist.

[JimSEA]

Sorry, a water layer beneath a granite crust bursting forth in a great flood is contrary to anything I or anyone else has observed. The earth just does not give any evidence to support a young planet and great worldwide flood.

[JimSEA]

I just look through the parts I was living in, I’ll have to read the whole thing now that I’ve the time.

[PizzaDriver]

Thanks for the “Heads UP”. I’ve save the link for my week-end.

Theoretical Geology makes more sense Gore’s climate “facts”.

[Robert A Cook PE]

Had not read that one. Thank you for the reference.

[SunkenCiv]

Thanks Robert A. Cook, PE.

I have not seen a world wide "breaking forth" either. I have seen Mammoth Mountain and Yellowstone. Neither I nor anyone I know has seen the millions of years. Perhaps you think the mountains that have ocean fossils on top rose from the depths of ancient seas. I think the mountains were shorter and the seas rose to cover them. We have the same evidence, the same data. Our interpretations of the data match our world view, our presuppositions, our beliefs. Have you read Dr. Brown's book? I am currently rereading Steven Hawkins's book A Brief History of Time. What a great mind has he. I do not agree but I can see how he reaches his conclusions. Do you have any book suggestion for me?
