Some ash from Mt St Helens went west, most went east.
A bigger explosion may result in more stuff being deposited west, but it's likely that most will go east. Not all, but most.

DENVER — In the last two weeks, more than 100 mostly tiny earthquakes a day, on average, have rattled a remote area of Yellowstone National Park in Wyoming, putting scientists who monitor the park’s strange and volatile geology on alert.

Beyond that, ash is just the start of the problems. Try major catastrophic global cooling (although since Yellowstone is further north than Toba, the impacts would not be as bad - but that is relative).
Holy is His name and beautiful are His ways..
The past is the best predictor of the future. If it happened again, odds are the deposition would be similar to what we see on the maps.
What a cockn'bull response....LOL!
You can't even admit when your incorrect....lol
WOW!
You just confirmed what I had surmised all along. You are an idiot pretending to have a clue in a subject you know absolutely nothing about.
For the record, I based my comments on the fact that for the past few hundred years, the prevailing winds, and the jet stream most always blow from west to east from the Pacific...(It's no secret)
In fact, if there were an eruption anywhere in the northwest U.S., the ash, approximately 95 percent of the time, would blow from the west, eastward....
Only a fool would even attempt to dispute this.
But it happened here!
LOL!
Congratulations, you just re-wrote one of the fundamental laws of Geology.
Gentlemen, I think you're both right, and are talking past each other.
Yes, the prevailing winds, particularly including the jet stream go west to east, and will blow a lot of ash to the east of the eruption. The jet stream winds are at an altitude of 6 to 9 km (20,000 - 50,000 feet) and can blow at close to 200 mph.
A supervolcano explosion can be in the hundred megaton range or higher. The plume of hot gas and ash can go well above 25 km. At that point, this superhot plume will expand in all directions in a huge mushroom cloud shape, and rain down ash.
Will the winds push a lot of that ash to the east? Yes. Will an appreciable amount of it fall to the west of the eruption? Yes. Will a lot of the finer ash and dust stay in the upper atmosphere for months, traveling all over the world? Yes.

A village is calling, they are looking for one of their idiots.
At least you got the message!
:o

Interesting map; I didn’t remember Tennessee having Atlantic access....

Cute, but really a foolish myth!
Potatoes fried in beef tallow are not unhealthy (canola is the dangerous one)
And the white bread is the only hazard in the burger.
The sound of someone speaking through their netherparts?

Some fail to recognize that the massive release of thermal energy can send dust and ash flying laterally at near sonic velocities.
told them that you were playing here
OMG! Yellowstone is going to blow its top!
No, it isn't. Or yes, maybe it will - 146,239 years from now.
Meanwhile, we keep shoveling the fast food down our throats and sitting on our butts watching TV. (And surfing freere... oh, never mind...)
The greatest threats to people's well being, BY FAR, are the FOOD that Americans eat (both the quality and the amount), which contributes to the epidemics of cardiovascular disease and cancer, careless driving, and smoking.

Yet some here actually dispute that prevailing winds have no or little effect on smoke/ash plumes from volcanos, massive wildfires or whatever is creating the smoke/ash.
Satellite images, are worth a thousand words.
It could happen ten minutes from now just as likely as millenia.
The trick of the low pressure system is related to the complexity of forces acting upon ejecta at the time of the eruption and subsequently ... I'm sure a super volcano would involve enough energy to at least effect a weather pattern to some degree, and none of those weather parameters are measurable to us today, 70,000 years later.
If we had a TARDIS, perhaps we could do some science directly, but failing that, you guys are arguing over speculative parameters neither of you can access directly for data. We have an ash deposition record. We have a current weather pattern, which varies by seasons. But not one piece of data on the weather patterns 70,000 years ago at the moment the eruption began is accessible to any of us.
