Cascades Volcanoes: When Sleeping Giants Wake 

I'm digging the early 80's soap opera music.... nothing like hearing upbeat elevator music while the topic of disaster and loss of life is discussed.

Rod Custodio is my grandfather and we are so happy to see him immortalized in this video. Thank you!

To all those complaining about the lack of information on the cascades I suggest finding the geological series from central Washington university. They are all on Washington geology.

I grew up 478 miles (as an arrow flies) north of Mt St Helens in BC Canada and when she blew her top, our dog alerted us to the water in our pool sloshing back & forth out of it!

A real estate agent saying "What about our quality of life, our small town values? t's not just my town." Talk about indefensibly compromised by self interest. I've read several of the recent geologic threat studies. The danger from Mt Rainier is real. Volcanoes don't care about property values.

I live in Washington state I've been to mt st Helens holy cow seeing the effects from the 1980 eruption was an eye opener for me, I hope and pray I never have to witness one of our beautiful mountains erupt

And here I am, living in the Ring of Fire. Alaska, born and raised. I witnessed the Volcano Mt Redoubt blowing up. I was getting up and getting the kids ready for the day. I went to take a shower and when I came out of the shower I was confused! I'm thinking I know that I might have been in the shower for awhile but I haven't been in there all that long!!!! Why in the world 🌎 is it darker now??!? I had no idea what happened. After we figured out what happened I went out to bring in our dogs. Covered up whatever we could. Put pantyhose on the carburetors on our vehicles and placed blankets or whatever around the door jams...... people were picking up ashes and saving them for whatever reason. We didn't live very far away from the volcano! Dang! Something you'd never forget

The more I watch doco's like this one, the more happy I am to live in Minnesota. No earthquakes, no tsunamis, no volcanoes, very few tornadoes. Wet enough that forest fires are rare, too flat for mudslides. The only geological impact here was the glaciers from millennia ago that left the great lakes and the many thousands of lakes dotting the state. Prime breeding ground for the mosquitoes that we bitch about. Occasionally we hit -40 degrees F in winter, but I'll take that any day over being buried under a 40 foot high wall of mud, thank you.

Nature doesn't give a hoot about how long you've lived there or how skeptical you are of geologic history or predictions. Review the Paradise CA fire and see how long it takes to go from serene tranquility to absolute panic and mayhem.

I live close to Mt St Helens and was raising a family when she blew. Watched it from my front yard. Was mass hysteria on the roads and in the stores. Ash all over and supplies could not be brought into our town as everything was shut down and rivers were trashed with debris flow. I would never want to go through it again yet to this day I still live on same block where I did on May 18th 1980 and won't leave.

I live within sight of Mt. St. Helens and never tire of it's beauty, the chance of it blowing it's top never enters my train of thought

I was living about 200km north of Mt St. Helens when it went off. We heard the explosion. Awesome power.

I had no idea how deadly volcanoes could be before recently when I started learning about volcanoe eruption index and the volcanoes that are high on that list. Thanks for the video

1:30 min: "Other than Mt. St. Helens, the Cascade range has been quiet for centuries..." No, Mt. Lassen erupted in 1915 and was active for almost a decade.

I love geology and especially structural geology. I may never be able to see any of the Cascades because of my age, health, and income,- but thanks to modern technology and videos I can daydream in virtual reality.. Awesome video.

That Realtor from Orting sounds a lot like the Mayor in "Jaws!"

Overlapping CME data with volcano data is an eye opening experience. 😳

And now 20+ years after this documentary was filmed, the populations in Orting and other towns in the Puyallup valley have quadrupled and there’s still only 2 roads in and out of Orting.

I am learning so much about Volcanoes. Especially about Mt St Helens. Thank you for sharing this informative video. Hope to see many more.

The "possibility"is 100%. Only timing is at issue.

The Cascade mountains are awesome. I moved away from my Mt. Rainier a few years ago, I miss it. Not seeing my mountain almost daily ,..I feel a loss.

Okay. I understand that My saint Helen's has erupted most recently. However it is annoying that people tend to forget that Mount Lassen has also erupted in the 19th century. Maybe not as violently as Helen's but Lassen did erupt 1914-1917 I hate that no one seems to acknowledge that in videos as it is a testament to how active the casades still are.

The town is built on a mudflow... In geology, when you see something anomalous, like a flat area in a mountainous region, you need to ask, why is this here? It's generally material that has washed or fallen from above that spot. A convenient place to build a house, yes. Maybe dangerous to actually live there though.

This video includes some commentary on Cascade volcanoes but largely it is a general view of volcanoes around the ring of fire: Japan, Philippines, Mexico etc.

Katmai(1912) and Pinatubo were the heaviest eruptions of the 20th century. They highlight the different hazards that volcanoes can create; de debris flows, lahars, collapses, lava flows, pyroclastic flows etc... all occur in the Cascades.

Good program. Thanks for uploading this. And thank you to Alison Kartevold as well.

What about Enumclaw? I lived there from 1955 when I got married to 1966 when my husband got transferred by the telephone company to Kent, Washington. The area of Enumclaw was called Osceola which I found out was called that because it was a "mudflow" from the last time that MT Rainier blew up. When you look at MT Rainier from Auburn where I now live you can see a rock formation on Rainier that looks, to me, like an ELK's Head. I am now 87, as of January 3rd, 2024 and I'm in love with the Internet! It is a wealth of information for free!

Mount Rainier, the mountain in the background in most pictures of Seattle, has more glacial ice than all other mountains in the contiguous US combine. The damage from the mud flow of a Rainier eruption is predicted to be like Hurricane Katrina multiplied by 5 and will likely be the worst natural disaster in US history.

I'm a Washington state resident and I love our mountains, I've been to Mt St Helens beautiful scenery and really cool debris field from the 1980 eruption

35 years ago this May 18th, my life changed forever. I survived the eruption of Mt. St. Helens when I was 6 years old. A part of me still died that day. I use to go up every ten years on the anniversary. I might have to change that this year.

As a child growing up in the 60's I use to go to Mt. St. Helens every summer for camping, hiking and fishing near and at Spirit Lake. I remember vividly the Day Mt. St. Helens erupted, my son was eight months old and we watched the Ash Cloud from Kent WA and stayed glued to the News. Now as a grandmother I live in the shadow of Mt. Rainier. Fortunately I am not in a Lahar Zone but I do need to be concerned about being buried beneath any ash the the mountain could throw my way. Still, all and all, this is Gods' beautiful country and I can't see living anywhere else. I am just more aware of the possibilities and am as prepared as I can be. As for the town of Orting, today they have a much better warning system. There are huge sirens all up and down the valley and they have drills regularly including getting the kids out of school and up to high ground during school hours.

Got it, by example.....it's a warning to the Cascades...that they will ignore until the day they go BOOM

The Cascade Mountains are here in relation to the Cascadia Subduction Zone which is about 55 miles off our coast 700 miles down from Vancouver, Canada to Cape Mendocino, California. The Zone last unlocked in 1700 sending a tsunami to Japan [they have a record of it]. MT Saint Helens has erupted more than the rest of the mountains put together the last time was in 1980. I learned this from Nick Zentner a geology professor at Central Washington University in Ellensburg, Washington. Yellowstone volcano is over a HOT SPOT like Killowea on the Big Island, Hawaii. The last time Yellowstone "BLEW" it was in Idaho. It is now in Wyoming because of Plate Tectonics. [The movement of the earth plates]

Saint Helens and her frequent eruptions(she was most active) has produced geological markers in the sense that her ash layers are used to date the surrounding layers.

Ooh look, what a pretty mountain... I'm gonna build my house right next to it....

What do you do when sleeping giants wake? You run like hell. It's about your only option. It's not like there's an "off" switch.

15:45 Yes what they aren't saying is that a 747 came very very close to ditching in the indian ocean in 1982. That Volcanic ash completely shut down all the engines and it was only a ton of luck and a skill that saved them.

It's been over 20 years, a good time to do an update on those interviewed.

Welcome to the 1990s time warp! The best piece of advice came from the Japanese government. Don't depend on the government, be self reliant. Help other's and be prepared.

Volcanoes in the Cascades and an apocalyptic caldera volcano to the east in Yellowstone. PNW is in a bind. However if Yellowstone goes all of humanity is in a bind.

I watched St. Helen's blow its top out my bedroom window. I was absolutely thrilled seeing the eruption but saddened with the aftermath. Still have some ash I collected around my house.

Jim Zimmer, et. al, another fantastic job of work. I'm living in volcanic Baja these days and I will always look back with fondness on my PA/work study year working with you and the producers. What a fun and informative addition to my MA in Criminal Justice experience in Spokane. I truly enjoy and learn from all your productions, whenever I stumble across them on You Tube. Thx. Jim T.

A Volcano is like a giant pimple, sooner or later is gonna pop!

I've lived by mt rainier, mt, adams, mt.hood..and st.helens..for the last 6 years I've been here in Alaska..right by mt redoubt, and Illiamna..I've seen them all emit steam...while it can be a bit unsettling, the view of those majestic mountains and ocean..worth my risk...but up here we're always ready for the unexpected...this is Alaska

To save your time, 10:00 to 20:00 min. then 35:00 to 45:00 Is ONLY about the cascades.. the rest is all rehashed footage and interviews, from Doc's I seen a hundred times, Your welcome, merry Xmas!

Almost 40 years since Mount Saint Helens blew her top

I will quickly and succinctly answer the question proffered at the beginning of the program about what do you do when a volcano becomes active and erupts. You can not negotiate with a volcano or manage or mitigate its destructiveness. You either get the hell away to safety or you subject yourself to the very real risk of injury and death. That is it in a nutshell.

Mount Shasta hasn't been a big ash producer ? just drive on the north side on the old military road and you will be plowing through three feet of ash for miles !

Great information that is well need Ed.

Titles video "Cascade Volcanoes" Mentions Cascades a few times while showing video footage from everywhere *_except_* the cascades.

I went to Shimabara Mt Unzen.. Saw the effects of the pyroclastic flow.. It is indeed mighty and a very beautiful area. .

I grew up in McLoud/Mt Shasta - great memories.

Good one Gill...everyday you wake up you should be thankful!

Such a special area. Just heed warnings and the danger is minimal. StHelens gave lots of warning

I like these docs. The narrator and the music are very pleasant to fall asleep to.

41:00 In all your complaining I'm not hearing you deny that Orting's in a danger zone.

How ironic for the real estate agency to name themselves "The Prudential" when prudence would have them build somewhere else lol

Individual responsibility - taking care of one's self. Great concept and much to learn from Japan.

I love this old stuff thanks. hows old mate from like the fire dept 39:58 "we have our own problems we cant help you" haha

Your programs are amazing . Thank you for sharing them.

I got there about 5 months after it blew up.i was stationed at Fort Lewis for 3years .It is so beautiful up there.

On average, Mount Shasta has erupted at least once every 800 years during the last 10,000 years, and about once every 600 years during the last 4,500 years. The last known eruption occurred about 200 years ago, possibly in 1786

Well done...great show!

I have family in this area. Between Mt. Rainer and the Cascadia subduction zone (which is actually responsible for Rainer), I do worry for them ...

"The Japanese government was not about to surrender..." Oh dear God no. "...to a volcano." Whew.

I explore caves. Since 1964. Yes, I get lost but evidently not enough. Found an unexplored cave 5 miles from an active volcano caldera. Since 2003 its been on my 'To Do' list. After the discovery I decided to save it for my senior citizen recreation needs. I retired after 2010. But felt active enough to do other things. Joined organized caving groups in Michigan, California, and just this month in Wyoming. Did start refurbishing a rain forest trail first completed in 2004. Have a nice view upwards of 10,000 feet to enjoy on rest breaks. Watching avalanches and vented steam. While the mountain that contains the cave has been previously scalded clean of life and blasted with volcanic material the cave survived. As do others. Such as Ape Cave located on the south slope of Mount Saint Helens. I was in it 12 years after that volcano exploded and saw no damage. Let me thank KSPS Public TV & PBS for being honest about science. To get dishonesty about science I look no further than Republicans.

The residents who live near these volcanoes and refuse to leave if erupted, Harry Truman would be proud of them.

I arrived in the Philippine islands a couple days after Pinatubo erupted. Spent about a week there trying to dig out the Navy base in Subic Bay.

Oh and what you're saying is that people in Japan were so more concerned about volcanoes that they didn't think that a huge tsunami could come because of an earthquake in the ocean

Excellent program

Excellent documentary.

If you live anywhere near Oregon, Washington, Idaho, California, etc, then you should be very wary of the volcanoes in that area. There are multiple dangerous, active volcanoes. I drove past Mt. St. Helens recently to see it smoking, and I can see Mt. Raineir in the distance of where I live. It's smoking, too. Be careful.

The most important thing to remember about any region of this world is the preservation of life as long as possible, avoiding any dangerous situations at all costs and even more so when it is always so eminent keeping people in constant awareness possible evacuation and in fear making every day The Day of Destruction and afterwards rebuild. Life is hard as it is with everyday hardships, let alone natural disasters, which can be avoided and yet are disregarded, trusting that each day of no activity guarantees many more days of safety. MOVE OUT AND LIVE

While it was an ok video, I wish they had spent more time on the Cascade volcanoes. I also wished that they could have spent more time on the shake and bake. I have watched several videos on MT Rainier and none of them had brought up the idea that an earthquake could trigger an eruption, other than this one. After the 2001 quake, I know where my eyes will be now if another big quake hits.

I live in Australia. We have no "active" volcanos but I think one day that will change.. Apparently there is a hotspot between mainland Australia and Tasmania. I live near an old now extinct (although some people in my town think it is just dormant despite no gas emissions) called Mount Canobolas. It is beautiful and the view from the top is great!

Wow. John Ewert was on the ground at Pinatubo when it blew. Definitely a guy who knows what a catastrophic eruption looks like, lol...

We live in the MT. Shasta, Mt. Lassen area. Not to close to them. I hope. But they are beautiful.

Mount Shasta: "Why worry about it.....?" I say WHY LIVE THERE TO BEGIN WITH?

The interruption of Pinatubo would be an excellent opportunity to create a waru waru ! A manmade collection of islands for agriculture with flood channels inbetween. If channels are perpetualy submerged, prawns and tilapia can be farmed in between. The ones that dry up annually are simply shoveled out onto the top of the islands surrounding them, thus refertilizing the soil. The condensation layer above helps offer some protection to crops and allows larger Harvest. It worked for the Mayans!

I feel like I’ve watched this before. High school class around 1989-ish, on VHS tape and supervised by a substitute teacher.

Love ur channel

I've seen the Ring of Fire firing - at Mount Yasur, Tanna Island in Vanuatu. Very spectacular but very small scale compared with some of the action described here.

#1 You don't go any where near them to start with. No visiting, and especially NO living around them! Last summer, my friends drove from WV to the Pacific ocean and visited Mt Rainier. They invited me to go with them, I gladly declined. They drove through Yellowstone, over the Rockies to Tacoma Wa, I stayed in WV where we don't have volcanoes, faults, and other "hazards" I feel perfectly safe here and have no desire to put myself in danger of any "natural" disaster.

REGUARDLESS, the view of mt. Rainer is amazing. I might have to visit or vacation there.

12:46 "Mt. Shasta's eruptions are larger and produce more pyroclastic flows than than Mt. St. Helen's." 14:40 "Mt. Shasta isn't a big ash producer." .....uhhhh

Omgosh. One interviewee said "From a training session, I learned I am responsible for my own life" These poor people really do need to be told when to eat, when to pee. Sad.

Popocatépetls last big eruption was January of 2020. It was still glowing and spewing ash as of August 2020 Novarupta is an interesting volcano.

I'm glad that they spent a considerable amount of time, discussing Mount Shasta and its environs. Pyroclastics, to my reckoning, are the worst phenomena, that volcanoes can inflict upon us. I would expect those, to at least reach Dunsmuir and beyond, to the South, perhaps Yreka to the Northwest and beyond. Acute Lahars (the second worst phenomena produced by volcanoes), might make it past Red Bluff, via the Sacramento River Channel, with a possibility of some breaching the topography, to go down the Klamath and Trinity River Channels. The first big Metroplex in Shasta's Danger path, depending on ambient air currents, would be the Ashland/Medford/Central Point, roughly 45 Miles away, to the North. Secondary acute, and later, chronic Lahars, would eventually work their way, all the way to San Francisco Bay, beyond the Golden Gate, thus, possibly causing a semi-permanent shutdown of the Oakland, Stockton, Southwest Sacramento, and San Francisco, Seaports. From ashfall and lava bombs, we could possibly expect places like Monterey, Merced, Fresno, Tahoe, and Reno, to experience at least serious--if not dire--effects. And it staggers the imagination, the extent of timber blowdown--could even reach into the productive Douglas Fir/Second-Growth Coastal Redwood Belts. So, in the immediate effects, much of Southwest/South Central Oregon, Northwestern Nevada, a little corner of Idaho, and as much as the entire Northern half of California, would become a big colossal write-off. Agriculture in California's Southern half, would become just a memory, for about 60 years. Then, with delayed ashfall and highly acidic toxic precipitation, the rest of the United States & Southern Canada, would buckle under. Much of the US & Canada, would also experience pandemics of Cardio-Pulmonary, Dermatologic, & Carcinogenic diseases. And then, we can only guess at the mid-term climatological effects, for the rest of the planet, for at least decades to come, though those would be very bad. Now, assuming that Rainier & Hood don't blow, in the same time frame, well, Seattle, Tacoma, and Vancouver, B.C., would just have to bear the burden, of being the most impacted--perhaps the ONLY viable--Seaports to serve the Easternmost Pacific Basin.

Very interesting!

Great video but I did LOL when that guy said planning for an attack form space !

I agree about the music.

I've lived in Southeast Alaska since 1975, currently living in Juneau the capital of Alaska. Having lived on the southern panhandle for well over 40 years, fear is being cut off of the supplies that most all rely on. Only the strong and the smart will survive. But I'm not in the lahar or tsunami zone. That's a good thing

3:32 if you've ever played the first Samurai Shodown game, the final boss Amakusa Tokisada in that is based on the leader of the Shimabara Rebellion with the same name.

very informative , not all that much on the Cascades Volcanoes though

It's now December of 2020 and they're all waking up now!!

I just tip toe around the house and let them wake up on their own

Correction 70% of known land volcanoes. More and more are found in the sea every year. Far more are oceanic volcanoes. Perhaps up to hundred of thousands.

Greetings !!! Thank you for sharing your thoughts, maybe we can try wake them upfor holiday ,good gift too. /sorry bad joke / keep smiling with lol politely merry Christmas

12:10 That woman embodies the key differences in Japanese vs Americans and why the Japanese are prepared for the natural disasters that they know will happen and why Americans are - we prefer to not worry about it and hope that our ignorance protects us. And that's why if there is a major eruption in a heavily populated area or "the big one" hits (whether off the coast of WA, OR, and northern CA or in SF/LA areas), it'll be devastating with far more lives lost than should be if we'd only bother to actually prepare for the eventuality. It's not like a tornado in the Midwest - we know its a possibility and we're prepared as best as we can be (with our early warning systems and tornado shelters), but it's only ever a possibility here. In WA, OR, and CA, it's an eventuality - it's not a question of *if*, it's *when*.

WOW very interesting super kool ,1st class great info.,,, AAAAAAAAAAA++++++++++++ again great video I liked it a lot ,keep up the great work..
