America's deadliest volcano enters unprecedented 72-hour tremor phase as eruption threat looms
Story by Chris Melore, Assistant Science Editor For Dailymail.Com • 14h

Washington's Mount Rainier has suddenly awoken and is buzzing with almost nonstop activity for days, stoking fears that an eruption could come soon.

The mountain is one of America's most dangerous volcanoes, towering over millions of people in major cities such as Seattle, Tacoma, and Yakima in Washington, and Oregon's most populous city of Portland.
 
Starting on Saturday, Mount Rainier has been experiencing constant vibrations beneath the surface which can be best described as thousands of tiny vibrations blending together.

The constant seismic rumblings were spotted by the Pacific Northwest Seismic Network (PNSN), where seismometers on Mount Rainier have recorded three straight days of nearly nonstop, high-energy seismic signals across the west flank of the volcano.

Liberals of the Pacific Northwest have got to find a way to stop the eruption.  The damage to the environment would be devastating.  It would be worse than cow farts.

[BobfromWB]

Lahars [ violent mudflows or debris flows composed of a slurry of pyroclastic material, rocky debris, and water that travel down the slopes of a volcano, typically along river valleys ] from Rainer's past eruptions covered ground as far as south Seattle.

Long ago, a geologist said that  due to it height [ 14,400 feet ] the pressure of an eruption would not find a ready outlet [ like blowing the top off ], but explode the entire mountain, devastating everything from Portland to the Canadian border. Millions would be killed instantly from the blast force, the flying house sized boulders, the molten lava and rock ash.

BTW: America's deadliest volcano is Yellowstone, not Rainer.

Volcanoes have been erupting since the earth began billions of years ago.

yeah but, it's because of climate change....

Yup.

[verga]

Yeah, but this headline isn't as Catchy, "America's second or even third deadliest volcano......"

[DB]

The USGS doesn't show much activity there for the last 7 days...

That area has high levels of instrumentation. Somebody is fudging something...

[DefiantMassRINO]

Yellowstone is a 'Super Volcano', 'Caldera', and 'Hotspot'.  Rainier is a pimple on the @$$ of the Cascadia Subduction Zone.

I hope Al Gore's Spotted Owls will be okay.

It's better to let the trees be destroyed by Nature than to harvest them for lumber.

[Canuck Conservative]

Rainier is a pimple on the @$$ of the Cascadia Subduction Zone

Don't dismiss it, that zone is still active, and contains recently-erupted volcanoes like Mt. Baker (1870), Mt. Lassen (1915), and of course, Mt. St. Helens (1980), only 100 miles away.

It's considered "deadlier" than Yellowstone because there's 3 million people nearby, whereas Yellowstone is largely in wilderness.

Wrong, when Yellowstone goes, most of the world will be effected, deaths will be in the billions.

It’s probably considered deadlier because it’s more likely to erupt in the near future than Yellowstone.  If and when Yellowstone goes, it’ll make a nuclear war look like a weekend snowball fight by comparison.  Most of the guts of middle America will be blown all over the stratosphere, and, as someone else said, billions are likely to die.

Well we better start rounding up some virgins to sacrifice now before the shit gets real.

[Smokin Joe]

Perhaps, but I don't believe Yellowstone has erupted since my wife's ancestors came across the land bridge.

No humans were harmed in the last eruption there.

[Smokin Joe]

Five year olds in the Pacific NW?

Well, no one said it would be easy.  Specially now that Epstein is dead.

[MeganC]

A "Take Back The Night" march and a protest at the volcano should do the trick.

Just to point out that Yellowstone in statistically overdue ...

[MeganC]

Just to point out that Yellowstone in statistically overdue ...

We live about forty miles from the center of the Yellowstone caldera. We have a hot spring on the property that we use for heating everything.

When the water leaves the spring the temperature is usually around 300F to 350F.

If it ever hits 400F we will get an alert, load everything up, and head for the Southwest as fast as we possibly can.

Best to head for somewhere south of the Equator which will buy you a few more years before the dust circulates and brings year round winter everywhere.

Very few places will be safe from Yellowstone's winter ash.

States on the East Coast, especially the southern and southeastern parts, would be the safest from the immediate effects of a Yellowstone eruption, with states like Florida and Georgia likely seeing very little ash fall. While the immediate blast zone would be limited to Wyoming, Montana, and Idaho, ashfall would affect a much larger area, so "safe" is relative and all states would experience some degree of disruption, with the severity decreasing with distance. 

    Most impacted states:
    Wyoming, Montana, and Idaho would be most affected by pyroclastic flows and immediate ashfall. States in the Midwest, like the Dakotas and Nebraska, would experience significant ashfall.

Least impacted states:

States on the East Coast, particularly in the Southeast like Florida and Georgia, would likely see the least amount of ash.

The reality of ashfall:

Even far from the blast, ash could still cause health issues and disrupt transportation and power grids, so no location would be completely unaffected.

Long-term effects:

A super-eruption could have global climate impacts, potentially leading to a volcanic winter and global food shortages, so even distant regions would be at risk from secondary effects.

It's been 'bubbling' in different locations in Yellowstone -- it's just very unreported.

Enough with the unnecessary alarmism ... there's no indication Yellowstone will erupt any time soon, some even say it's now in the waning phases of eruptive history

Doomsday predictions make great headlines, but c'mon, let's deal with reality here

Don’t think that was alarmism - the poster certainly wasn’t claiming that Yellowstone is about to erupt, even within our lifetimes.  So it was more of a theoretical discussion.

Being reasonably and proportionately prepared for various threats or eventualities is never a bad thing.

And the most important thing to prepare is your mind.

On 9/11 all of the deaths in the second tower were caused by denial. Those who did not deny the threat made it out.

The last eruption (a rhyolite flow) was about 70,000 years ago, and the last caldera eruption about 640,000 years ago.Present levels of activity there do not indicate any imminent eruptions in store, though eventually, it will likely happen.

The Cascade Volcanoes have a more recent history of being active. Likely the top will not blow off, but the side blow out (similar to Mt St. Helens). Which way it goes could have a big effect on casualties and damage, although we got three different ashfalls from St. Helens in North Dakota (the thickest about 1.5 cm.

[Smokin Joe]

Perspective:

Mount St. Helens made it farther than the map indicates, but that was not a crop destroying event.

Is it reasonable to guess a Rainier event would be similar in size to St. Helen event, only in a much more populated area?

[Smokin Joe]

Yes.

[Cyber Liberty]

Yes.

That would be really bad!  Did I  read the tremors have settled down?  I know there has been a lot of concern about Rainier over the years, blowing it's top ala Mt. Saint Helen.  The casualty count could be truly astounding!

[roamer_1]

Crap. We will get all that ash if it goes. Last time, when St Helens blew, we got better than 4" of ash all at once, and then a couple weeks of more.

It gets to where you don't know where to put it. Seems like snow, I know, but snow melts away eventually... The ash piles don't leave.

Next thing you know, you're digging a hole for it.
Then you stick it in your ash hole. 

[DCPatriot]

Yes.

Geez @roamer_1

Maybe think again about buying that roller right now.

Seems there's a good deal of disagreement....

With a little luck, Rainier holds off until we're safely gone....

Well, thankfully, the only eruptions and pyroclastic flows around here happen in my bathroom after a night of bad chili.

Naw... It's coming, sooner or later. Putting a megacity at the foot of a volcano is like spitting in God's eye. Folks ought to know better. Pompei should have taught em something.
