Quake Watch 2013

reply to post by whatnext21


its not showing anymore,
must have been a dud

Hmmm...

Research shows quakes in 3 states were caused by fracking.

news.msn.com...

Not exactly what the title alludes to. At least not directly.
Turns out they are talking about wastewater injection overloading local faults.
Then, 'remote/ dynamic triggering' can cause local, small swarms.
In some cases, that can lead to a bigger, local quake, even months later.

*******See, Eric!********
Like water slowly erodes away rock....they are slowly coming around!
Just hope they fully awaken soon!

Anyway, an interesting read.
Check it out.

OK so if you buy the story, why were there earthquakes in these places before fracking?
perhaps these quakes they mention may have happened anyway. Were they fracking in 1897?

I don't believe earthquakes are the issue with Fracking, it is the underground water contamination which is the main problem people should be concerned with.

Actually, a type of 'fracking' dates back to the 1860's according to these sources:

en.wikipedia.org...

www.guardian.co.uk...

They used to use liquid & solidified nitroglycerine!
And eqs have even been caused by water injection for geothermal use.

But part of the problem now is high volume, high pressure, high rate & high viscosity.
Not to mention chemicals, horizontal wells & especially the large increase in the number of wells!
Around here, they are getting 'greedy'. Numerous wells on small plots.

Like the difference between breaking an egg in half or squeezing it in your hand.
The more cracks you make in the shell, the weaker it gets!
If there is a link to remote triggering, we're in big trouble!
Especially with how many small, unknown fault lines there could be.

I don't know if there are regulations restricting the number of wells per site?
I would think there would be.
There are requirements as to the smallest acreage that can be used for a well.
I believe around here it is ten acres. That's a lot of 'crackage' in some areas!

Another problem, eqs aside, is all the empty spaces the removed oil/ gas create.
Just like old coal mines that eventually cave in. The voids have less support.
Manmade sinkholes in the making!
Humans don't know all the possible ramifications of their interference yet!!!

And all the pressure & viscosity from injection wells are another potential problem,
especially near fault lines.
That always makes me think of the cream filled cupcakes I used to make.
If you squeeze in just a little too much filling...you get major 'crackage'!

Dang it!!! Now I'm hungry!!!

yeah they have been using hydro fracking here in Wairakei near Taupo since the 1960's, but no increase in earthquakes in that area during that period. In fact bigger quakes occurred pre-1960's.

from that wiki article

As of 2010, it was estimated that 60% of all new oil and gas wells worldwide were being hydraulically fractured

Well whats the alternative?
park up your car and hitch up a donkey and bray?
The only way to stop fracking, is to stop using fossil fuels.

Here is the info from the CalVO monthly update concerning this swarm of activity.

Long Valley Caldera and Mono-Inyo Chain:
Eighty-two earthquakes of M>1 were located in the Long Valley Caldera, with a maximum of M3.0.
In the late afternoon of 17 June 2013 a flurry of earthquakes started in the Long Valley Caldera east of the town of Mammoth Lakes, California (in an area known to geologists as the south moat).
The swarm produced about 100 earthquakes over 5 hours before petering out; most were too small to be felt by humans (a M3.0 was the largest; many events were below M1.0).
The earthquakes originated at ~ 8-7 km depth where a small volume of partially molten rock is likely to reside...

seismos can record weather too!
SNZO currently showing another storm like we had 23 days ago earthquake.usgs.gov...
lets hope its not another "once in a decade" storm like the last one, 3 years in to the 2010's they might have to start re-categorizing these.

I don't believe earthquakes are the issue with Fracking, it is the underground water contamination which is the main problem people should be concerned with.

Just as I clicked reply I saw WOQ had said much what I was about to say. Nope, don't agree with you on this one Muzzy. Earthquakes are a problem especially when they may serve to weaken otherwise dodgy casings. In all cases of contamination as often as not the contamination occurs because of casing problems. If the casing is good the well is sound and the pressure theoretically at least should stay where it is put and the frack fluids should remain below the theoretically impervious layer between the gas bearing layer and the aquifers.

However, the very nature of shale is that is can easily split and it does so both horizontally or vertically. If this was not the case then fracking would be a totally pointless affair. The Wikipedia page on shale might be of interest.

Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness,

About 2 miles from my house is an outcrop of shale on the hill above us. You would not need to frack this as you can crumble it with your bare hands. It is reddish in colour (rich in iron and contains water deposited iron nodules.)

Despite what Wiki says in this instance vertical cracks are as numerous as horizontal. It is my guess that if we had an earthquake this would all collapse in a pile ready to remove and use as material for creating a paths - excellent for that.

Basically shale, when unbound by other strata, is a very unstable rock with little strength. When you create an explosion, you also create an implosion and the implosion as as much instrumental in creating fractures. Any fractures caused by earth movement can further destabilise, and any destabilisation near casings can lead to leaks.

In the Wikipedia article you will note a picture of shale overlain by limestone. Not the least bit uncommon in oil/gas producing areas. We sit on limestone and there is also gas in the area - but no fracking as yet. Limestone, whilst not a rock that fractures in the way that shale does, is not a dense rock as for example basalt and is easily weathered and cut into by water, hence we have the classic karst landscape of the Burren not far from us in Clare.

What I am rambling on about is the fact that gas and oil, and fracking, all occur in areas that have rocks that are not the most stable and thus any trauma to the casing and/or surrounding areas can instantiate conditions that may give rise to penetration of the supposedly impervious overlay whether by casing bypass or direct through the strata.

Well I know what I am trying to say anyway!

Sounds like an Irish winter!

The only way to stop fracking, is to stop using fossil fuels.

Curtail the US military for a start - they must use gazillions of litres of the black stuff and I am not talking about Guinness.

Personally the idea of having a pony and trap very greatly appeals and if I could I would. Unfortunately where I live there is no public transport worth speaking about, and the nearest bus stop is 3 miles away so transport of some sort is a necessity, but there are many millions of people who needlessly use their own transport, even to the ridiculous extreme of getting the car out to take the kids down to the end of the drive.

There are also plenty of synthetic alternatives for oil and almost ALL of the requirements for oil, plastics, car panels, paper, cloth etc etc could be solved in one fell swoop if we returned to the state where it was illegal in most western countries NOT to grow hemp. (And I am not talking about the high THC stuff just ordinary hemp)

Fracking is NOT necessary - there are alternatives.

EMSC have 7.2 and GFZ have 7.0

At present the original 7.2 Mw for the PT network (Pacific Tsunami) is still in the list.

Any bets on whether this drops out of the Mag 7 band anyone?

Not understanding this dark and mysterious statement/question. What is to come and why does it need oil fields?

You mean to 8?

Nah ,will remain 7.2 because they are on vacation on Sandwich Islands.

Because if it is a foreshock and IMHO it is for 8+ we shall see unexpected phenomena like earth exploding in that area.

For now, it looks like it is back into the 7+ range, but who knows where it will be in 30 days...

Hey,guys and gals...

Check out this seismo from vesuvious, just a couple hours ago!

Is this weather related, or is this a little harmonic action??

portale.ov.ingv.it...

This one looks mechanical to me.

On the BKE V (Vesuvio) tab it looks to be quaking?
and big daddy, super volcano Campi Flegrei is getting in on the action, small but stirring nonetheless?
