Mount St. Helens VS Yellowstone (Yellowstone Monthly Update - May 2024)

Quick correction of a slip of the tongue -- it's subduction of the Juan de Fuca plate that is fueling volcanism in the Cascades. Also, the map showing ash distribution only includes that part of the Mount St. Helens ash fall that was more than an inch. Lesser amounts fell over a much broader area. You can see a generalized map of this area in the USA at pubs.usgs.gov/gip/msh/ash.html.

Next up : hummingbird vs. tyrannosaurus rex.

Great presentation- thank you! You should have WAY more visitors.

Thanks for these reports! You always do a great job of explaining things in a way that is easy for a layperson to understand. I always look forward to the updates because I find Yellowstone a fascinating place and enjoy learning more about it

Mike, ya might want to get some antacid for that NASTY indigestion you suffered at the end there! 😂😂

I was on Mt. ST Hellen’s the year before it blew it top off.

Well done Mike!

I always enjoy these videos but I really enjoyed this one

ty for this info i find it fascinating and shows me what mt rainer could do when it blows i live in one of the lahar areas for rainer

The range of ash from St Helens is always underestimated. We had considerable ash drop east past Butte Montana. and some spots in the mountains received heavier amounts. I experienced this first hand in the Georgetown Lake area near Philipsburg when visibility was reduced to less than 50 yards.

Thanks for the presentation and update! Subscribed.

Thanks

Thank you very much, Mike. Climbed St. Helens in 1976 with my Dad. A wonderful memory.

Great report. Thank you.

Cool comparison

tnks mike! :elbowbump:

...this bout is like putting an ant up against an elephant! I love the cascades and have hiked and camped from Shasta to Garibaldi for years. I listened to a fascinating lecture on estimating eruptions from remnants like welded tuff/ignimbrite. (not a geologist, is that spelled right?) The speaker offered analysis and modeling of deposits of various ages/lava compositions, sizes of eruptions etc and is quite convinced that we have wildly underestimated the volume of essentially all VEI-8 eruptions. There's one caldera, I think Long Valley, so 2-ish hours from Los Angeles, is the one, but I've also seen 10,000km³+ for La Garita. Geology Hub, another fantastic channel has a video including or dedicated to it, but I actually hadn't gotten to it yet, now I'm even more interested to find out what has been found and how it can be explained.

Wow. We can comment now.

I have a question, we love to talk about the massive eruptions at Yellowstone, but how common are (relatively) small eruptions at yellowstone?

Exactly 44 years ago today my dad said "let it blow... What harm coikd it do?"
