How Dangerous Are The Northwest's Volcanoes? 

And a water reservoir downstream at Lake McCloud.

I'm disappointed nothing about CALIFORNIA

Have you ever really looked closely at the ground north of Shasta? Huge lava rocks not part of a flow but more of a blast distribution. If you travel from weed on 97 towards Klamath falls and you gain altitude where you can see the valley north towards Yreka you see “hummock’s” these are from a huge ash eruption where extreme amounts of mountain and ash blew out. It looks in my uneducated eye to be miles further than mount saint Hellen’s blast radius. There where mountain ridges there to slow and deflect the blast but I want to say that from what I can see Shasta has had some serious explosive eruptions as well. Geology rocks😊🤟🏼

“...... a handful of small towns sitting alongside...... IT IS base”???

Ya was wondering when they were going to talk about Pahto

Yeah Rainier makes up like one-eighth of Pierce County (includes Tacoma) and when it erupts the national park will be vaporized by lava, the resulting lahars will destroy Kent, Puyallup and most of Tacoma, and Seattle’s port (which is mostly on the Duwamish river) will be fouled up with ash, mud, charred trees and toxic gases. As a born-and-raised Washingtonian I’ve had quite a few nightmares about it, but luckily it might not happen within my lifetime since the last eruption was while Lewis and Clark were first starting their expedition and our volcanoes normally each take about 300-400 years between eruptions

Not to mention Shasta and Lassen. Terribe doco.

@@lhaviland8602 they must be talking major eruptions because Baker last erupted in 1880... Not some 1000 BC. 🤣

Today when Rainier was out when I was on a ferry from Vashon back to Seattle I saw what seemed to be a secondary crater from some previous eruption to the left of the peak well below the tree line. And also it once apparently erupted sideways like St. Helens, looking like it does today about 3000 years ago.

@@badpiggies988that might’ve been a flank collapse with a major lahar

Californians hate when people talk about the happenings on the West Coast and don't include them. It always has to be about them, lol.

@@Excalion88I mean lassen is deffs worth mentioning concidering it only erupited 100 or so years ago.

I was going to make a snarky joke about how volcanoes erupting in California make things better. But then I remembered Rainier would erase big parts of Seattle, which is also an improvement. Tell you what. Let's bring Northern CA and Southern OR together as the State of Jefferson, and then they can be part of the PNW club.

correction, in the video they said that Mt. Baker last erupted in 1000 B.C. not 6000 years ago. but not much better really. They also forgot to add Mt. Adams to the list of Major volcanoes.

Lassen too it was the last eruption besides st helens.

There are a lot more that have been active in the last 10000 years in USA. And a volcano can come to life very quickly, look at Chaitén from Chile, as a good example.

I'm guessing they weren't included because they haven't been active for a very long time? Just a guess though. I was wondering the same thing too

I'm pretty sure this video is only washington and oregon so no shasta or lassen. Both could blow their lids potentially at any time, kinda makes you perpetually nervous if you live nearby one of these beautiful monsters

Glacier Peak is the big one. It’s the only volcano in the lower 48 states that has the same explosive materials as Krakatoa and other volcanoes that have explosive eruptions.

@@bigrooster6893 No, Glacier Peak is not the 'big one'. Rainier is far more dangerous, as evidenced by its inclusion on the Decade Volcano list, a list of 16 volcanoes on Earth with violent histories in close proximity to large urban areas. Rainier has so much glacial ice (more than any other peak in the contiguous US), that when it goes, it'll flood the entire Puyallup River Valley with boiling mud.

I agree with you, however, Mt. St. Helens is the most active volcano in the cascades. Other than that, I agree

@@the-eu8xp I aswell am not a geologist, just a really smart 12 year old who makes volcano and earthquake related content on my RU-vid channel. I do however, know that the CVO (Cascades Volcano Observatory) needs to focus on lesser known volcanoes like Mt. Jefferson, Glacier peak, and Three sisters. Three sisters has some hope though, with the new renewal of volcanic earthquakes and magma rising. I am very stressed that monitoring at Jefferson is so very weak, because its last eruption was more violent and explosive that Newberry yet they both happened at the same time. But alas, Mt. Jefferson only has 1-2 seismometers.

@@the-eu8xp yes I agree, however I think that any potentially active volcano should have less than 1 seismometer, therefore, we cannot see the full picture of its seismicity and if Mt. Jefferson were to have a life threatening eruption, geologists wouldn’t know because of its extremely low tracking. Any future volcanic eruption from Mt. Jefferson could (and most likely would) release deadly lahars to nearby towns.

What makes Rainier scary is that ANY eruption is going to be catastrophic. Rainier has more glacier mass than all the rest of the Cascades combined. Just a little bit of oozing lava could send brutal lahars all the way to Puget Sound. In fact there's record of an enormous mudflow, which is NOT associated with any volcanic release. Maybe a glacier got too big, maybe a jiggle from an earthquake. Either way, zero warning, just a 100ft wall of mud and trees and boulders crashing towards Tacoma.

There listing the 8 most dangerous volcanoes in Washington and Oregon

@@peanutchicken13 read the title, they are listing major pacific northwest volcanoes, and they missed five Mt. Meager and Mt. Garibaldi in Canada, Mt. Adams in Washington, and Mt. Shasta and Lassen peak in California.

Definitely. It'll trigger other northwestern explosions, triggering other natural disasters like avalanches, flash floods, tsunamis, etc. So yeah, we're done.

I am dead because I live in Seattle

​@@hasanabid7724 There is a fighting chance, actually. I will explain: First off, know the mountain. Rainier is a stratovolcano. This means it's "temperament" is NOTHING like what you would see in Hawaii. Hawaiian volcanoes are all shield volcanoes. They aren't as gassy. The dangers from Rainier would include pyroclastic flows, lava bombs, lahars, lava itself (depends on how close you are to the foot of the volcano in that case, because the lava's viscosity is closest to sticky peanut butter rather than heated honey) shaking earth, and really poisonous air. Expect levees and plumbing to fall apart because infrastructure has not been updated in a donkey's age. Any suburb just beneath the volcano is TOAST. Second, watch it if the quakes start hitting above a 4-5 on the Richter scale. If it does, LEAVE. These usually are a harbinger of danger in eruptions. A nice trip to Texas is in order. Texas is volcano free. Do not doubt the warning on tv if it does come. Just GO GO GO. Third, buy insurance when your place is not shaking or baking, like right now. Your valuables can be replaced. Your family and elderly cannot. Take photographs, computer laptops, your clothes, dirty or not, and consider your wife's jewels DEAD LAST. There is such a thing as volcano, flood, and quake insurance. If you are really that troubled, buy it, and skimp on new things like cars and luxury. Last, immediate escape: if the governor says to evacuate, try to stay away from the main byways and take the backroads south and towards California. Head AWAY from the volcano and hug the coast. Do not stop until you hit San Francisco. DRIVE there, no bus! More immediate danger would require you to make a beeline to a boat and head for Canada-bribe your way on one if you must!! Rainier is very similar to Vesuvius in that it has a major city under its foot and it should be capable of the same tricks that killed Pompeii. FLEE! FLEE!!

Mary Katherine Goode why would I go towards California since I live in Seattle, wouldn’t going to Canada be a better idea?

@@marykatherinegoode2773 come to California with active earth quake plates

And it's active again....

Volcanoes don't have routine timers. They erupt whenever they want to.

Rainier isn't even 650,000 years old

Yes. Read my post.

Mt. Garibaldi

At least it’s not Yellowstone I would study rainier instead of panic

@aranphor Fumerals or funerals you mean? 😂 update yourself to current events.

Can you post a link to that info?

@@shastina5493 you are uneducated and maybe you need to study geology and volcanology before you run your mouth you know nothing of child

those are fumerals and they have been doing that for years and no that mountain is not bulging child

@@davidconejr4206 Took you two minutes to try to correct your comment. Who needs to study? Not me! The earth going through major change and you just want to attack instead of wake up. Peace out!

St Helens is closer to Portland than it is to Seattle, by about 2 and a half hours.

Active again too... July 2019

Yellowstone is not a cascade volcano. It is on a hotspot. Cascade are on a subduction zone.

Also not likely to erupt anytime soon.

I doubt that vulcanologists that cover only the cascade range would talk about it

Gee Terry, what about Krakatau for that matter!

Wonder if they are talking about explosive eruptions. But either way small eruptions shouldn't be ignored.

LOL you beat me to it. A tip of the hat sir. 👍
