I am the volcano.

Want to know what it would be like? Really?
Go and study the years 536 to 538AD.
Only one thing. Time it times at least ten.
536 was the years the earth went dark for quite a while. There was one massive eruption...most likely Tambora and then a couple years later another BIGGER eruption most likely in Central America..Ilopango.
Ping to #55 for Idaho guys and what are your thoughts on prevailing winds in the area?
I am the volcano.
Yes, Yellowstone WILL erupt.
Between 10,000 years from now and 250,000 years from now. Near certain. The super-eruption IS predictable! But only to 50,000 years.
Hint. Yellowstone is still a caldera, a volcanic cavity that still has to warmup, fill up with magma to create the 6,000 to 12,000 foot dome over the surrounding 3,00 foot regional elevation, THEN continue filling to stretch and break that crust around the new mountain peak.
This is NOT Cascade volcano tripping off every 200-300 years. This is NOT the Mag 8.5 earthquake off of Oregons coast that is overdue on a 300 year cycle.
This is a 400,000 to 600,000 year cycle. It has gone off so seldom we don’t really know it’s period. Yet.
Everyone assumes that if it erupts that it would be massive. That doesn’t seem like a sound notion. It could just burble until the pressure subsides. I sneak out farts all of the time. Well, sometime not.
3. Pop another cool one.
My grandma collected ash in Hayden, ID from the Mt. St. Helens eruption in 1980 and sent vials of it to all of her grandkids. I still have mine somewhere. That stuff was unbelievably fine, like talcum powder. It's astonishing how fine volcanic ash gets when all the gases dissolved in the rock blow the liquid rock to pieces when the pressure gets released.
Here's a pic from Spokane in 1980. We would feel right at home these days! Little did these kids know that they were way ahead of the times!

About a year and a half ago, we were at our river cabin which turned out to be about 70 miles from the epicenter of a 4.0 quake.
Had loud boom and pretty good jolt.
The ash from Mt. St. Helens did follow winds aloft. I spent a week sweeping it near Cheney, WA. Or, if you’re saying you’re so close it won’t matter, I definitely agree with that... (I mean when you’re up there — try to schedule a trip to the Bay Area around the eruption).
Near Cheney (Williams Lake, there was around 6 inches of ash). My parents had to drive through ash the whole way from there back to Tri-Cities. It appeared the Toyota Corona air filter did not pass a single particle of ash! But the trunk lid had collected a foot on it. I was waiting outside in Kennewick for them to get back. The blast sound woke me up that morning and I got out of the shower wondering WTH were the black clouds overhead. Took pictures but someone at Payless Photo stole them.
On that ash graphic people should realize those depths are in millimeters, not inches.
The roughly 2 inches it shows where I live (and that WOULD be highly dependent on winds), would be about the same as Mt. St. Helens dropped here or a bit more. But, of course, the devastation to the east would be incomparable.
So all the area that produces wheat, beans and corn with 30 mm (up to 1.8”) of ash on it
The question about prevailing winds after this sort of event is a bit different from a large single-cone volcano eruption, because (a) the ash to lava ratio would be lower, but (b) both would likely flow longer. That means statistically there is more chance of ash falling in all directions over several months if not years. Also an event that large might severely distort normal weather patterns. It would be likely that large impacts would be felt in all directions. At the same time, it seems logical to expect the pattern of destruction to be skewed in an eastward direction since higher altitude winds would most frequently be westerly, and not due west all the time.
The direct effects of the molten lava would not likely be much further afield than about the extent of Yellowstone Park or possibly 50-100 miles.
We only have approximate guesses available as to what would actually happen and it’s possible that the impacts might be spread out over a long enough period of time that it would not be the complete annihilation some predict. Two or three years of climate disruption would probably not be long enough to trigger a glacial advance on a large scale. It would probably be like the late 1970s with a number of severe winters in a row. Since the effects would be much less in Eurasia, the climate “engine” would not take as bit a hit as in a Milankovitch type downturn.
But I don’t claim to know what would actually happen. It could be anywhere between a considerable disruption over several states to a continent-wide apocalypse. Also I suppose there is more than one type of eruption, I have read about past eruptions of this moving hot spot, which has moved over millions of years from northeast Nevada to Yellowstone. One eruption formed the lava fields at Craters of the Moon National Monument in Idaho.
That’s cool you heard the blast and went “WTH?”
I hiked Mt. St. Helens summer of ‘75 before the blast when I was working in Longview, WA. It was a gorgeous mountain. I remember getting severe altitude sickness driving on the south side of the mountain and only got a short hike in before quitting and having to get back to sea level. That was the only time that happened to me — severe, splitting headache.
That was a lot more ash around Cheney that CdA or Hayden. You figure that the ash fall drops off as the reciprocal of the square of the distance from the blast center.
I would be more concerned about a CME (coronal mass ejection) because I think the damage would be much more wide spread and it would take years to repair, if ever.
EMP would have to be human caused and a more isolated event, easier to repair/recover from probably.
The Carrington event in the 1800’s didn’t do as much damage as it could have because people did not use electricity except for telegraph back then, now days it would probably knock out the entire electrical grid, perhaps even world wide.
Horse and buggy here we come.
THE SUN WILL DO WHAT IT WANTS!
The volcanic formations on display at Mt. Lassen National Park are wonderful. You’ve got the mountain itself with its own caldera at the top and steam fissures, Cinder Cone to the east, and huge lava flows all over the place. It is very impressive walking along the front of the lava flow at Cinder Cone looking up at the jumble of enormous cooled lava rocks. The front wall of the lava flow must be 20 to 30 feet high.
Nah.
We'll all be dead from starvation if we're not already shot for food by our neighbor.
“You figure that the ash fall drops off as the reciprocal of the square of the distance from the blast center.”
Given constant winds.
I was surprised that staying and skiing at high elevation in Colorado I did not get altitude sickness.
Click bait for sure. Paced like a click-bait article designed to be read in 50 or more segments written at a 4th grade level.
