And maybe not.  TBH is just wanted to start the thread.

Hundreds of small earthquakes have rattled Mount Rainier this week in the largest swarm of tremors in more than a decade. But experts say there’s no need to panic—at least not yet.

"Currently, there is no indication that the level of earthquake activity is cause for concern," the USGS explained. "Earthquakes are too small to be felt at the surface and will likely continue for several days. There would be no damage caused by such small events."

Swarms are clusters of earthquakes that happen in rapid succession, sometimes just minutes apart.

As of Thursday morning, over 300 small earthquakes had been detected around Mount Rainier, the largest of which was magnitude 2.3.

From Wiki.  Seems an eruption would do harm.

https://en.wikipedia.org/wiki/Mount_Rainier

Due to its high probability of an eruption in the near future and proximity to a major urban area, Mount Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list.[14] The large amount of glacial ice means that Mount Rainier could produce massive lahars that could threaten the entire Puyallup River valley and other river valleys draining Mount Rainier, including the Carbon, White, Nisqually, and Cowlitz (above Riffe Lake).[15] According to the United States Geological Survey's 2008 report, "about 80,000 people and their homes are at risk in Mount Rainier's lahar-hazard zones."[16]

How ironic that the Pacific Northwest will fall into the ocean before California or Florida.

Makes sense on this timeline that the coolest of the three - both literally and figuratively - would be the first to go. 

 

I hope my friends, who are scheduled to summit Mt Rainier this weekend, opted for the training package that included dodging avalanches and magma

Arne Saknussemm should’ve paid for the training package.  Rookie mistake. 

 

The audio/video of him walking in the darkness is about as real/raw human emotion as you will ever hear.

I was living in Kennewick, Washington when Saint Helens blew.  Being east of the Cascades the weather is always sunny and clear there, and when I woke up that morning, deeply hung over, I walked out of my apartment to drive to get coffee at the convenience store and instantly saw the several inches of ash covering the ground and my car.  

Giant, dark rolling clouds filled the sky, and I instantly assumed there had been a nuclear war, that the ash was fallout, and I would go back inside and turn on the TV and figure out when I would die from radiation. It was quite the relief to realize it was only a volcano natural disaster. 

One thing nobody talks  about now was that the ash fell in such fine particles that everyone’s radiators immediately became clogged and cars overheated, and had to stop.    I was a court administrator for the Benton Franklin County Superior Court at the time, and trials were conducted in the town of Prosser about 20 miles away, as they were the county seat.   It took many weeks before people could drive 20 miles and not have their cars overheat. This included most first responder vehicle vehicles as well.  It was definitely a thing that impacted everyone in the state for a while if they were in the plume penumbra. 

 

 

i was 5, we were living close enough to get inches of ash.  I couldn't be convinced that it wasn't snow and my parents basically had to tie me to the couch.  I remember seeing the big whitish grey explosion cloud in the distance(didn't impress 5 year old me all that much) then the sky going grey for days and all the associated clean up/freak out/vehicles, heatpumps, gutters, roofs damaged.   Towards the end of the clean up the fire department came and washed the ash into the storm sewers(probably wouldn't do that today).

 

Somewhere in the family collectables are mason jars filled with ash.  as you describe, very fine and powdery.

I was 30 miles from Mt St Helens the day it blew; everyone knew it was going to, it was just a matter of when. Dad took us down to see it one last time (it was a gorgeous, Fuji-like cone) and we camped with a tall ridge between us and it. The next morning when it blew, everyone on the other side of the ridge, the ridge that marked the exclusion zone, died. All we got was a lot of really warm ash, of which I still have a little jar. Those lahars and pyroclastic flows are scary as shit.

There were 2 or 3 smaller but ashy eruptions after the big one; a town called Ritzville (narrator: it isn't that, at all) about an hour west of Spokane got 10+ inches of the stuff. Later that summer I went to stay with my older brother, fresh out of the Army and living in Lewiston, ID working as an air traffic controller, and the ash was still piled up in drifts across Eastern Washington when I rode the grey dog over to visit.

How was there not a 70s/80s band called Pyroclastic?

The concert visuals and tshirts sell themselves. Pyroclastic Rocks 🤘

Things been heating up over on the Kamchatka Peninsula, too. Ring of Fire got ants in its pants?

we’re headed to Seattle on Tuesday and Bend later in the week. I’m sure it’s fine if you bring good shoes for any magma you come across.
