Whats going on at yellowstone?

all montana eq's on 11k depth...perhaps an piece of bedrock is crushing to an expanding chamber???

Just saw this one come in ....

Region: WYOMING

I just belatedly noticed the September earthquake swarms and starting paying serious attention to Yellowstone for the first time since the last swarm, which I recall was around New Years' Eve several years back.

There has been some comforting news about the effects of a supervolcano eruption:

www.newscientist.com...

So some scientists thing that supervolcanoes' climate impact may be reduced by the fact that so many sulfate particles are released that they come together to form large particles, and their mass causes them to fall to the earth faster.

And now that I think about it, supervolcanoes happen every 50,000-100,000 years on earth, which makes them a pretty regular occurrence in geologic terms. And yet you never hear about this or that species of, say, deer or bear that went extinct because of this or that supervolcano. And you never hear about this or that ice age/glaciation that was caused by a particular supervolcano.

For me, this is the evidence of the gun that didn't go off, and it tends to be supportive of the study linked above. No doubt Yellowstone erupting explosively would be by far the greatest disaster in US history, but at this point, I don't think it would bring down human civilization or anything like that.

716 pages,

obviously nothing is going on.

it will maybe blow in 10-40kyrs.

or in the next 5 mins.

oh well.

and still she"s continue "swarming".....cracking up.. weakening the strenght of the crust....

perhaps......

I just saw this: www.vice.com...

Collapse was incredible and Ruppert's an excellent thinker / talker so I can't wait to see this.

Has anyone been able to find a revised map of the magma chamber since they've now decided that it's 2 1/2 times bigger than previously thought?
Article
I read that a team at the University of Utah has revised the map, but I can't seem to be able to locate one.
Thanks!

chamber 2.5 times bigger....really ??? how could they be soooo far wrong earlyer.....
most possible reason can be that the biggest part is recently become molten rock.....
that would inplicate that an eruption is near...also count the swarms in...YVO is riddeling about it...an complete new type of behaviour of the caldera !

if the temp of the caldera underneath is really rising than the expanding rock will crack couse temp rising making small eq"s in an swarm...


correct me if i'm wrong...
molten rock has moore volume than solid state
moor volume...moore heat by pressure...
moore heat
moore rock melting...

Let's put another log on the "maybe supervolcanoes aren't so catastrophic after all" fire:

"However, recently scientists have suggested that Toba did not sway the course of human history as much as previously thought. For instance, prehistoric artifacts discovered in India and dating from after the eruption hinted that people coped fairly well with any effects of the eruption."

www.livescience.com...

India is right in the path of the Toba ashfall, yet they coped just fine with the eruption 70,000 years ago? Something is missing here.

Has anyone identified a single species that went extinct from either a Yellowstone or Toba eruption? Not that I know of.

How catastrophic could it have been if it didn't caused some dumb hoofed animals (e.g bison) or whatever, reliant upon grazing, to go extinct?

interessting subject....time will tell :-)

reply to post by ressiv

Yeah, right? That's quite a large increase. I sometimes use a Yellowstone Map overlay on Google Earth to view the EQ activity, it shows an approximate caldera boundary. I'd be interested in seeing a revised one now that they have re-estimated it's size. I would imagine that it will include areas near Norris Basin which are presently thought to be North of the Caldera itself.

ETA: But then again, the Caldera and the Magma Chamber are two different things I suppose...

Guess we can say there is a swarm again?

If you read the article, it is not definitive. They only suggested the affects of Toba weren't as widespread as theorized. Their evidence is thin. One, long thin core.

Also, East Africa may have been the exception to the rule. It may have had it's own isolated micro-climate. For example, November was the hottest November on record. Yet, much of North America was colder than normal. As the article states, it would take many more samples from lakes to prove the hypothesis. And, shouldn't you have more than just East Africa in your samples. This might even explain why humans survived in Africa. Maybe there was a warm high pressure system over the continent due to weather systems. East Africa could have been a heat island. Just like our modern cities have become heat islands. Some meteorologist "suggest" that the city heat islands steer bad weather around them. Maybe the same was true in Africa. Maybe it was an Eden compared to the rest of the planet.

Maybe indeed, but that still doesn't change the fact that there's apparently not a single species - anywhere - that scientists have identified as having been made extinct by a Yellowstone, Toba, etc eruption. Anywhere on the world.

Nor has a single instance of glaciation been tied to Yellowstone or Toba, even though we've been in an ice age for the past 2.6 million years, i.e. for the last 3 Yellowstone eruptions. It's not that hard to get glaciers forming and moving south during ice ages, yet Yellowstone hasn't had that effect even though it's erupted 3 times during an ice age. Seems to me like Yellowstone eruptions would have caused glaciers to form if they really caused a huge global reductions in temperatures, lasting years.

Those facts are hard for me to reconcile with some of the more dire supervolcano prections.

Whilst I do not disagree I have to wonder if the 'scientists' would actually know what effect it had. Most of this stuff is guesswork. Now it is however a fact that the effect of volcanic winter is short lived and thus these eruptions may not be a contributing factor to extinctions and/or glaciers and icecaps BUT they may provide a tipping point.

how could they be soooo far wrong

That my friend is a very good point. They did a tomography survey to produce this (2009):



So are they saying the tomography was a waste of time? Something does not seem right. The image above was produced in 2009. This report on the BBC web site is quoting the same figures as the result of the 2009 tomographic survey.

Somebody somewhere is twisting things intentionally or otherwise. These 2013 reports appear to be about the same survey.

edit on 20-12-2013 by sageturkey because: Linky

I guess what I am saying seems correct. As you point out there seems to be no updated map and curiously your link has vanished.

I believe what we have here is a storm being blown up about old information by some person or people who do not understand the beast and are looking for some scary news while all else is quiet.

60 Minutes will do a story about Yellowstone and two other worldwide volcano threats on Sunday. Be sure to check it out.

Ressiv mentioned something odd about the mag 3.4 quake that occurred on the 11th. Anyone else notice all of the activity that preceded the event?
Almost all stations in the vicinity caught it, definitely not background chatter...
YLT 01/11

thank you sageturkey..:-)
here the Original post from quakewatch 2014...

weird pattern of YMR station..also visible on YML station
looks like stress building up to the 3.4 magn. than released....
an intrusion?

i,m aware that YMR is very sensitive.....

an blob of magma rose out from the depht and shatterd to the ceiling of the plume ?
