Volcanic activity off the hook all around the world!!

[skookerasbil]

Im sure the k00ks will find a way to blame this on global warming but to the regular folks, this news is certainly far more of a threat than CO2!!

Would actually like to hear Ray's take on this.......coupled with all the earthquake activity in recent months in the ring of fire, are we looking at some large scale event here?

Dang.....was just thinking maybe not so good an idea to post this up............poor Matthew might not be able sleep for days!!

I'm sure he will find a way to make it man caused..

Even the size (magnitude) of quakes globally has increased.. Been while since I was on this site.. Even Yellowstone has had a significant uptick in quakes, but it is winter, when this usually occurs.

An increase in volcano activity is directly related to tectonic stress and therefore earth quakes would also follow suit becoming more frequent and stronger.

Dang... 1,661 quakes in the last 7 days.. Up from 1,332 this same time span last year... That is a substantial uptick globally.. Means lots of stress on earths plates is waiting to be released.

Predicting earthquakes and volcanic eruptions is incredibly difficult and inaccurate. To be fair, there is some evidence that small earthquakes can be attributed to fracking. But on the bright side- a large eruption can spew billions of tons of ash into the upper atmosphere where in will spread across the globe. And that my friends will block out much of the sunlight reaching the earth and COOL the planet. Ergo- volcanic eruptions solve global warming. It's all good!

USGS: Volcano Hazards Program CVO Mount St. Helens
On March 16, 1980, the first sign of activity at Mount St. Helens occurred as a series of small earthquakes. On March 27, after hundreds of additional earthquakes, the volcano produced its first eruption in over 100 years. Steam explosions blasted a 60- to 75-m (200- to 250-ft) wide crater through the volcano's summit ice cap and covered the snow-clad southeast sector with dark ash.


.Within a week the crater had grown to about 400 m (1,300 ft) in diameter and two giant crack systems crossed the entire summit area. Eruptions occurred on average from about 1 per hour in March to about 1 per day by April 22 when the first period of activity ceased. Small eruptions resumed on May 7 and continued to May 17. By that time, more than 10,000 earthquakes had shaken the volcano and the north flank had grown outward about 140 m (450 ft) to form a prominent bulge. From the start of the eruption, the bulge grew outward—nearly horizontally—at consistent rates of about 2 m (6.5 ft) per day. Such dramatic deformation of the volcano was strong evidence that molten rock (magma) had risen high into the volcano. In fact, beneath the surficial bulge was a cryptodome that had intruded into the volcano's edifice, but had yet to erupt on the surface.

The reason I posted that is to demonstrate how rapidly, and with how much deformation, a stratovolcano can build up to an eruption. The siesmic profile for an immanent stratovolcano eruption, thanks to St. Helens and Pinatubo is fairly well known. Not so for the caldera volcanoes. So the one in Italy does bear careful watching.

I don't think the Alaskan volcanoes present any particular danger. The winds simply don't carry even a large eruptions ash that far for that latitude. Katmai is an example of that. Popocatepetl is a differant case. Situated where the ash and aerosols would quickly spread around the world. 25 million people in the immediate vicinity, a nightmare if an evacuation is required. Were it to do a Crater Lake number, the results would be catastrophic.

The only thing that we can do about volcanic eruptions is get out of there way. Where they are adjacient to heavily populated areas, that can be challenging.

By the way, in the lower 48, there are only two cities with active volcanoes in their city limits. Both in Oregon. Portland and Bend.

Predicting earthquakes and volcanic eruptions is incredibly difficult and inaccurate. To be fair, there is some evidence that small earthquakes can be attributed to fracking. But on the bright side- a large eruption can spew billions of tons of ash into the upper atmosphere where in will spread across the globe. And that my friends will block out much of the sunlight reaching the earth and COOL the planet. Ergo- volcanic eruptions solve global warming. It's all good!

Even Pinatubo sized volcanoes only do that for about 2 or 3 years. Sorry, just not enough volcanoes.

Yellowstone or Toba would end any and all global warming really fast.

Well, for a decade or so, but the results would be such that the civilization after that eruption would not be producing that much GHGs. Still, the world would continue to warm until the present levels of GHGs in the atmosphere declined back to normal interglacial levels. But no one would be caring about the port cities and sea level any more. There would be survivors, of course, but living at a much lower level than we presently do.

Are all these earthquakes happening because Obama lowered the sea levels

Great stuff Ray.........just seems to me all these plates, even in the central US are far more active now as compared to when I was growing up. IDK.....maybe we never heard about it back then?? Just have this sense that something big is coming from this ring activity.

a scientifically unsupported assumption at best..

Hmm, any idea what some scientist say created the little ice age? Or every heard of the super volcano under Yellowstone?

USGS: Volcano Hazards Program YVO Yellowstone
The three caldera-forming eruptions, respectively, were about 6,000, 700, and 2,500 times larger than the May 18, 1980 eruption of Mt. St. Helens in Washington State. Together, the three catastrophic eruptions expelled enough ashand lava to fill the Grand Canyon.

If you extend the logic- the large eruptions would cause millions of people to die, and thus reduce the amount of fossil fuels being emitted, and thus your man-caused global warming would be stymied. The fact is, that is about as sound as any of the hypothetical remedies proposed by the "scientist" who think we can stop or alter significantly any climate change that is occurring. How can you tell a phony scientist? He's the one who claims the science is settled.

Yep, tell you're butt buddy OLDROCKS. He isn't up to speed.

 

[Old Rocks]

Well, Moron, it would end the increase in CO2 from anthropogenic sources, it would have a one time increase from the eruption of the volcano itself, albeit a minor one. But the 400+ ppm of CO2 we have put in the atmosphere would not magically go away, and would continue to warm the earth. The last time we had that much CO2 in the air, the sea level was tens of meters higher than today. So the survivors of that initial decade would still face a rapidly warming planet.

As far as being up to speed on the effects of a very large caldera eruption, I suspect I know far more than you do about that.
