Quakes and earth's crust crumbling potential

10/02/2009 3:06 AM

Dear all,

the recent series of earthquakes at ever increasing frequency of occurrence brings to mind a potential for the crumbling of the earth's crust sooner than later.

We're fortunate that we have only one-at-a-time and not two or more simultaneous earthquakes distributed worldwide.

Combined with global warming, it appears that the crust is also expanding inexorably leading to surface ruptures and consequent quakes, Tsunamis and attendent disastrous misery for the planet's occupants as a whole.

Will the cognoscenti cut out wise-"cracks" and give a well thought out contribution to the discussion?

What exactly do you mean by "crumbling of the earths crust?"

Earthquakes are a normal effect of the build up and release of energy along fault lines.

They will happen, and will continue. Some larger some smaller.

Dear Steve,

"What exactly do you mean by "crumbling of the earths crust?""

"Crumbling" usually means breaking up of some solid into smaller fragments, losing "homogenuity"(I hope I got the spelling right). The earth's crust is non-homogenous, but has some continuity within the bounds of very large pieces as "Tectonic" plates, somewhat akin to broken cream on thick full fat milk.

This "normal effect of the build up and release of energy along fault lines"

is itself a result of normal shrinking and shrivelling of the earth's surface caused by its cooling down over the aeons somewhat akin to a stewed apple skin while getting cooled.

"They will happen, and will continue. Some larger some smaller."

We need not worry excessively about "Normal" occurrences, but we have to be concerned when there is an escalation of the frequency in an abnormal way.Please refer Europium's pointer.

Regards

D.Ramakrishna Naidu

I am not so sure why you are worried about it... Oh well.

Any one who is "inclusive"# minded will be "worried"!

#Sanskrit:"Sarvam ekam". "Sarva jana sukhino bhuvanthu".

Transliteration to English:

The entirity (of the universe) is ONE. May all people (leaving out none) live in bliss.

Any one who subscribes to this philosophy will be worried.

Tectonic plates are forever moving in relationship to their neighbours. Away , closer or sideways.

During the Tsunami the plates overlapped by more than 20m over a distance of more than 1000 km.

Temperature does cause rock to crumble but at most only skin-deep. (I have witnessed that in the desert - at 40+ degC 5 - 10 mm thick flakes came off)

According to the US Geological Survey (USGS), "There is no evidence that earthquakes are becoming more frequent, it is simply that more earthquakes are being recorded - especially small ones - as extensive world-wide monitoring networks continue to expand. The number of large earthquakes, however, remains stable year in and year out. The US Geological Survey's Earthquake Hazards Program website provides data on the frequency of earthquake occurrences."

The USGS estimates that several million earthquakes occur in the world each year. But many go undetected because they occur in remote areas or have very small magnitudes. The USGS National Earthquake Information Center locates about 50 earthquakes each day, or about 20,000 a year. Up-to-date statistics on the number of earthquakes worldwide and in the United States can be found at the aforementioned website.

Just curious, but is your question motivated by this article (http://www.indiadaily.com/editorial/4199.asp - sorry, link no longer available) in the India Daily?

Dear Europium,

thanks for a Good Answer, and I have voted accordingly.

I'll start from the end of your reply.

"Just curious, but is your question motivated by an article in the India Daily?": No sir. It was a hunch, backed by a sub-conscious monitoring of world events as they unfold daily through TV/Newspapers etc. but then your pointer to an article as above is reinforcing my hunch.

"The biggest problem, according to sources is that the tectonic plate shifts have increased the number of serious earthquakes in the past one year by 80% and the rate is exponentially increasing."

Thanks again for a very useful posting.

Regards

D.Ramakrishna Naidu

GA for a concise response.

Too bad last link (I think) may have caused it to backfire.

"GA for a concise response."

Thank you.

"Too bad last link (I think) may have caused it to backfire."

The OP opened this thread on a similar premise which, in my view, makes the last link relevant. As is usually the case with such material, viewer discretion is advised.

From what I can see you have partially defined the problem, The next step is to consider solutions, in most situations that we attempt to solve problems, there are solutions. If there aren't any solutions we have to consider the consequences.

If there is no honor, nobility, grace, dignity etc. in dying when the earth crumbles and sends us off to our individual makers, then there is only inevitability. So if all that is left is to exit this world, whether we go kicking and screaming or just go, then your discussion strikes me as interesting but I tend to put it in the Nostradamus, Mayan calendar category. My calendar still goes past 2012 if I am wrong I will die. If I am right I will die.

You probably put google on overtime with "cognoscenti" nice touch.
