Just a piker compared to Yellowstone.
And there's not a damn thing we can do about it.....

That’s a nice little volcano site.
The volcano that might be doing something soon - or not - in Iceland is not Katla but Grimsvotn. He has links that tell history and so on. Grimsvotn erupted in the late 18th century and cause much death due to toxic fumes that even killed people, animals and crops in England. It is not a nice volcano.

Grimsvotn Volcano, Iceland
Melt water continue to flow from Grimsvotn volcano, Iceland. The rate has slowed compared to previous days. An increased in electrical conductivity in the Súla river indicates that geothermal water is draining from the western side of the Skeiðarárjökull glacier. Earthquakes continue to occur under Grimsvötn volcano indicating that floodwaters flow under the glacier. There is no indication the volcano is currently erupting.
More on Grimsvotn volcano...
Volcanoes of Iceland...
When is NObama supposed to be in Indonesia?
“Just exactly when is the Great One visiting Indonesia on this vacation?”
I hope the teleprompters are not damaged by volcanic ash.
bttt
Catastrophism ping.
Bush’s fault...
>>>We can still see the devastation of the Mt. Toba eruption. On the Malay peninsula, many hundreds of miles away and a location with no volcanic activity, the volcanic ash is literally hundreds and hundreds of feet thick. Any kind of similar event will have catastrophic consequences for the entire world.<<<
Yeah, it would suck on so many levels it’s hard to imagine, especially when you’re living up here in Alaska. However... humanity DID survive the last eruption of Mt. Toba. If it happened this time around, a fair number of us have a lot more knowledge of things, and I think, for humanity, at least, it would be a huge strain and there might be some locally severe circumstances, but the species would do all right. Going back to a 17th century - or, for that matter, a 7th century - state of being would be hugely awful, but we’d have the knowledge from now to bring us back pretty quick.
Or God may have other plans. Who the hell knows? LOL
Volcano ping.
No way Meg Ryan is played by the Chubaca.
My bad! I thought the poster was referring to the Alaska eruption. Still, they are all related...just more distantly. The Icelandic eruption heralds the creation of new oceanic plate in the Atlantic, the eruptions in Indonesia are the result of the subduction of oceanic plate in the Pacific. They all are connected.
After the 1815 eruption, it snowed on Independence Day, 1816 in NYC. At least, I think that was the year. Whatever Mt Merapi decides to do, it’s not going to be pretty.
Isn’t this the area of children sex slaves?
Largest volcanic eruption in 400 million years, producing 2.500-3.000 cu. kilometers of ash, and 1 trillion tons of aerosols (including 200,000,000 tons of sulfur dioxide - (SO2).
Cloud was more than 34 kilometers high. Ash covers India between 1 and 6 meters deep. (May have started following cooling period).
6 year period during which the largest amount of volcanic sulphur was deposited in the past 110,000 years, followed by 1000 years of the lowest ice core oxygen isotope ratios, temperatures were colder than during the Last Glacial Maximum at 18-21,000 years ago. Sea level was 160 feet below current.
Global temperature drops average of 21 degrees. Volcanic Winter lasted about six years. It was followed by 1,000 years of the coldest Ice Age on record. Warming begins again 1,000 years later.
It is believed that the 1% human genetic variation stems from this time. No other species shows such a small variation. Genetic evidence suggests only 10,00 human adults survived world wide. May be event which caused rise in modern racial differences - Professor Stanley Ambrose of the University of Illinois.
70,000 B.C. - Lower Pleniglacial Stage
Coldest period. Most of northern Europe and Canada, and southern South America were covered by kilometers thick ice sheets.
1259 A.D. - Very large eruption, Origin Unknown.
Twice the size of the Mt.Tambora eruption in 1815 A.D. - this would make a Volcanic Explosivity Index (VEI) = 8 or more; possibly qualifying as a Super Volcanic Eruption.
Antarctica ice core data; Norwegian tree rings; England and Europe - numerous references to dark skies and unseasonable cold, one obscure reference to pillar of fire in western sky; Chinese reference to pillar of fire in southern sky; Indonesian description - near Krakatau - magma rose in a miles wide column into the troposphere lasting for some days before subsiding, according to references.
National Geographic (TV) ran a piece a year or more back on a group of scientists attempting to verify this eruption with hard evidence. They tried to get to the likely island in Indonesia by small plane, but the turbulence was too severe.
Next they tried by ship. Landing their skiff on a sandy beach, the photographer filmed the surrounding areas while the scientist went to collect rock samples. Suddenly, tremors began and as they increased in severity, everyone rushed back to the skiff and departed.
There was an explosive eruption hurling boulders into the air, narrowly missing their ship as it was underway. When things calmed down, they returned. On the very spot the photographer was filming earlier, there was a 10 foot boulder. Tremors began again.
They left without any samples, just photographs and films, unfortunately proving nothing. It is simply too dangerous an area to study. The truth of the matter will remain a mystery.
1815 A.D. – Mount Tambora Erupts
Volcanic Explosivity Index (VEI) = 7. (100x greater than Mt. St Helens)
150 cubic kilometers of rock, 200 million tons of aerosols, Year without a Summer – largest explosive eruption in recent historic time.
90,000 killed in first few minutes of the eruption, red and brown snow falls in Europe during the "Year Without Summer" or "1800 and Froze to Death".
For Comparison Purposes:
1980 A.D. - St. Helens, Washington (USA) Erupts
1 cubic kilometer of ash.
Volcanic Explosivity Index (VEI) = 5
If I'm prepared for The One-Hour Meltdown then I'm prepared for this to, yes?
It's always something.
Would be the least of your worries. Especially if the eruption caused a subsidence tsunami...
Unlike a fracture tsunami caused by an uplift in the crust, the wave generated would not break on hitting the shore - like the tsunami some years back off Indonesia.
This wave would be a standing wave many kilometers broad and high at the crest, traveling at 300-600 mph and only break only when hitting some higher structure - like a mountain range.
And the "ripples" would likely travel around the world inundating most coastal cities — and most of Alaska.
Returning to the 7th Century might seem like Heaven... Think worldwide chaos and people everywhere in a state of shock like nothing seen in modern times.
Eek.
