I wonder...if the Three Sisters blow, will that be a trigger for Yellowstone? The Three Sisters would look like a roman candle compared to a Yellowstone eruption

They're hundreds of miles apart.

Even Rainier and Mount Saint Helens, as far as volcanic arcs go, are fairly far apart. They do NOT share a common magma chamber.

Basically an immense amount of nonsense on this thread by people with an essentially non-existant knowledge of geology about activity being linked between distant volcanoes.

Err, as far as "volcanic arc volcanoes" go Mount Saint Helens and Rainier are fairly far apart.

Just so Mt. Hood stays napping. That baby is way too close for comfort here.
