The Active Volcano in Washington; Glacier Peak
Вставка
- Опубліковано 27 чер 2024
- There is only one volcano in the state of Washington other than Mt. St. Helens which is capable of and has produced multiple eruptions similar in size to Helens's infamous 1980 eruption during the last 20,000 years. The volcano I am referring to is still technically active, having last erupted a mere 300 years ago. This volcano is known as Glacier Peak, which could pose significant hazards to up to approximately 70,000 people if it was to ever erupt again.

I was in highschool when a substitute teacher asked which active volcano was the closest to everett. I was the only one who knew that Glacier Peak even existed. I love living in the PNW
If you look at it closely, you realize Glacier peak has numerous domes on it. It is really hard to get to, but its drainage is of a worry to the Skagit Valley in the event of a pyroclastic flow . It is really under studied and needs more monitoring equipment on it.
Most of the volcanoes in this part of Washington are like this.. look at baker and the 3 sisters.. not sure if it's true but im lead to believe that even cultus mountain is actually a side vent of baker.. and that land slide on its side is actually a volcanic push.. I just think this part of Washington is all one big volcano and no where is actually exclusive to one zone.. i believe an eruption could occur miles away from any established volcanic peak and they would just relegate it to the nearest volcanic peak.. I just consider the northwest Washington Cascadia range one big volcanic field.. I believe there are volcanic peaks lost to time in Mount Saint Helen's like events many times over as well as new volcanoes that have yet to form..
Absolutely. I live in Shelton and my daughter lives in Lakewood. Camera geologists always say Cascadia won't trigger the volcanoes. We do not believe them. All these things are like an asteroid strike; not really a damned thing you can do about it, so enjoy every minute of every day. And go to the ocean. Take the dogs. And the kids. ❤
Yep, its inaccessibility is big part of why it's so dangerous. Hopefully, there will still be plenty of lead time before the volcano erupts.
Thanks for covering Glacier Peak in the North Cascades. I tell people about it all the time, but hardly anyone knows about it or what it has the capability of doing, if it erupts. Similar to Mt. Rainier, it has active glaciers and lahars can pose a threat, even if the mountain does not actually erupt. They are planning on putting more monitoring equipment on it, this year. Its not the easiest place to monitor or put equipment on, as you may guess.
Yup. That’s my neighbor, and the historical lahar flow paths were definitely a consideration when we purchased our property.
Lahars are no laughing matter, unless you say it La-Har-Har-Har! 😃
Good work!I had no idea that Glacier Peak had so much destructive potential.
Oh yeah, great news. 🤔
Thanks as always, Geology Hub!
Interesting that Glacier peak erupted in the same year as the last Cascadia megathrust earthquake.
I want to note that the eruption in question has a century long margin of error. While it could have erupted at any point between 1600 and 1800 CE, 1700 CE seems like the best fit in my opinion.
@@GeologyHubwhat do you think the chances are of the megathrust correlating with the last eruption??
Cool, I asked about this in a separate post. I'll go remove it, thanks for any info! TBH, I didn't really know much about Glacier Peak at all. That's why this is my 2nd viewing today.
@@snowblind.scientists deny connections unless there’s strong evidence. When i was young 50 y ago, many denied connections between San Andreas and geologic activity in Yellowstone or PNW. Now with more data and better instruments connections are being found.
@@snowblind. Considering the uncertainty, quite small.
Nice coincidence: Nick Zentner just released one of his ‘on the rocks’ videos doing a detailed look at the geology of Glacier Peak and surrounding areas.
Interesting note: the volcano itself is
Nick's videos and CWU lectures are awesome.
I believe it was Nick and Gary Paull scouting Glacier Peak for a future Nick on the Rock episode, not an actual episode but it will be coming next season. Nick is the best! Been following him since 2019.
GeologyHub and Nick should definitely do an MCU crossover thing sometime
I love Nick's videos! I will need to go find that one next..😊
@@farmermark2067I enjoy their scouting videos more than the finished product. There's a lot more to learn and they have pretty good chemistry together
Thanks for all the hard work on these videos
Always so much info packed into each video. Thank you😊
Brilliant content as usual. Love it!
Some of your Mount Saint Helens video got featured in FOX 13 Seattle's coverage of that volcano's recent earthquakes.
My family and I lived in Arlington for three years. I didn’t realize at the time how active this volcano is. Beautiful country! 👍👍👍
I miss this type of video in where you introduce volcanoes ❤❤
Glacier Peak is one of the most dangerous volcanoes in Wa. state
Your opening shot of “Mt Baker” is Mt Shuksan, which I believe is not a volcano, but next to Baker.
There are islands near the mouth of the Skagit River that are landlocked. Lahars from a Glacier Peak eruption made it out to Puget Sound and surrounded the islands.
I'm wondering if the 1700 eruption of Glacier Peak had anything to do with the last subduction earthquake in 1700?
Technically yes? Same system. Not sure if one can cause the other though
Hey bud, the photo of Mt Baker you have at the beginning is actually Mt Shuksan, its nearby nonvolcanic neighbor
Thank You.
Oh, lordy, I live in NM, where the Valles Caldera is, and I just had a💡moment. There are two hot springs locations I have soaked in within the Jemez mountains, and I just realized they are heated by the Valkes Caldera magma remains! 🤯
Valles Caldera interesting yeah the Rio Grande rift valley is still extending and thus the area is still volcanically active with magma at depth which feeds hydrothermal systems. The next zone of major activity along that rift is likely to be beneath the Socorro area was that is where the large scale ongoing magma intrusion injection is occurring.
Glacier Peak is deep in the Cascade Mountains you barely see it from Everett! You see it but you are apt to think it’s a bigger version of the non volcanic mountains nearby. I call it Glacier Peek, because that’s all you get, a “peek” of that mountain.
Unless you live in a town in the boonies. I got to see it almost every day.
Hi could you do a video on Tsunami in Majorca in the mediteranian?
Thanks.
Speak of the Devil! I literally made a post on my FB earlier about how Mt. St. Helen's really isn't the volcano you need to worry about in WA State. It's Glacier Peak and Mt. Rainier.
Thank you for the update!
Anyway you can make a video on the 2 craters rings outside Mountain Home, Idaho? I just visited & know it has to be volcanic in origin
Glacier Peak also has hot springs as well
I grew up in Darrington. If you went about a mile up the road from my place you could get a nice big view of old GP. It looms like it's watching over everyone.
When the Juan de Fuca Plate finally slips causing a 9 Earthquake will any of the Wa Volcanoes erupt?
Its a distinct possibility though we might expect a bit of a lag time as there was a number of active volcanic episodes during the 1700's and 1800's along much of the cascade volcanoes if I remember correctly(note in the comments that the Glacier peak last eruption timespan has error bars of several hundred years 1700 is just the most statistically likely center of that estimate . Most subduction zones are only partially locked since it requires the right mix of pressures and temperatures and water helps lubricate faults but in the Cascadia subduction zone the Juan de Fuca plate is very young ocean crust which hasn't had time to settle out and become cold and dense while the high rates of erosion have lead to extreme sediment deposition rates from Pleistocene glaciation and outburst floods which we now know is predominantly been lithified by mineral bearing fluids to turn the kilometers of sediments into thick sedimentary rock units primarily consisting of sandstones and siltstones that extend the locked zone all the way out to the top of the trench infilling sedimentary rock units. This huge locked fault surface effectively arrests motion allowing large amounts of energy to build up and at some point it is going to fail. Yeah I would expect when it does the movement will lead to an interval of increased melt feeding activity in addition to direct seismic effects.
It should be noted that there is limited reduction in melt temperatures of cascade melts as the underlying slab is too young to have accumulated large amounts of water like seen in old subduction zones so the melts which are generated in the cascade subduction zones are hotter than typical for subduction zones which is likely part of why the range is less volcanically active than other older subduction zones.
I just saw another report that volcanologists are concerned about Mt Rainier having increased activity as well. Threatening Seattle and Tacoma with mudslides.
Hi geology hub! A swarm of eq occured earlier today at lake toba supervolcano. I Would like to see what's your thought about this minor event
GH,
Have you applied the USGS threat index to Campi Flegrei? I know it's in the top 5 hazardous volcanoes in the world but I am curious as to what the USGS scale number would be
I suspect they use different ways to measure because not using US numbering .
@@Dranzerk8908 It's not numbering that is US, it is the measurement system that's a US thing
7? I thought we only had 5 active volcanos... Maybe it's 5 active strata volcanos... 7 active volcanos is too many.. this might keep me up at night...
Compared to other volcanoes in the PNW, Glacier peak is not as well known, since it is surrounded by other mountains.
Anything bad that has to do with volcanic ash is way worse.
1700 was last cascadia fault large slip wonder if it's connected. Bet he will say it is.
Can we infer then that Glacier Peak's early eruptions occurred during an interglacial period, similar to the one we're now in? Or is it just amazing co-incidence that the eruption type is the same now as it was back then?
I don't think we can the history of glaciation in the Cascades is complex and the dacite magma composition doesn't seem likely to have much to do with glaciers but the volcanic plumbing system.
Sure there will be an effect from the weight of the ice pushing down and increasing the threshold needed to trigger an eruption with the clear spike in activity when the ice retreated showing us this was definitely a factor but the point is this is still a young volcanic system.
The Cascades are an unusual subduction zone due to the young age of the ocean crust being subducted meaning that there is much less water to reduce the melting point but the crust subducting so volcanism is far hotter than is typical at a subduction zone with the full trench of sediment meaning there is a high sediment load and helping insulate the buried oceanic slab such that in combo with the young crustal age the Juan de Fuca slab material is also significantly warmer than is typical for a subduction zone. This all means that the local melt source is much more regionally specific to each volcano as there isn't the large amount of water to lower the melt temperature.
Huh. Glacier peaks most recent eruption was the same year as the Cascadia earthquake of 1700. But GP's eruption was phreatic so likely no connection.
Was there a large Cascadian earthquake around the same time as Glacier Peak erupted last time? If so which came first the quake or the eruption?
Is it just a coincidence that one of the G.P. eruptions was 324 years ago- same year as the Cascadia subduction 9.0 disaster?
Was the last eruption of Glacier Peak tied to the last Cascadia megathrust earthquake or was it a total coincidence that they both happened right around the same time?
As beautiful as the opening picture of Mt. Baker is... that's actually Mt.Shuksan. Not the first to do it, and won't be the last because they are so close to each other, so no biggie. From the angle this was taken, Baker would actually be directly behind the camera, and you would have seen it if it spun around.
Do you think the active period in the cascades in the 1700s and 1800s was caused by the 1700 cascadia subduction zone quake? More fuel to melt when it got subducted?
Natives keep telling neanderthals that each cascadia slip many many volcanoes go off like 42
( Not an insult it's the legal name per max plank of the non sapien )
Why is it that Helens is the only one to erupt in the last 80 years?
Mt. Baker
Glacier Peak
Mt. Rainier
Mt. Adams
Mt. St. Helens
What are the other two since you said 7?
How did you get into geology?
lol, this is geology, not geography.
I hate autocorrect
Autocorrupt
@@demoncatman6575 that’s what it really is lol
😎
Great topic GH , thank global warming for melting the glaciers at Glacier Park otherwise we'd be a heck of fix.
Wrong
If the glacier is melted and freed by volcanism wouldnt it be a jökulhlaup and not a lahar, which is a volcanic glacial flood freed by heavy rain?
One day there might be increased eartquakes occuring. Then and only then should you be worried. For now it sleeps.
PNW gang wya?
within the next 6 years they are all going to blow.
Interesting, except that the picture of Mt. Baker is NOT Mt. Baker, it is Mt. Shuksan. Another AI mistake.
A mistake possibly, but nothing to do with AI.
This is not AI. You know nothing about AI so stop talking about it
😭😭😭
i cannot handle the narrators voice. Hopefully it's just really poorly done AI
It is his real voice (affected by his autism, as he explains in the intro to his Iceland drone flight livestream back in April). Now who do you respect more - the person who makes a well-informed, well-structured video packing a hell of a lot of information into a four minute slot virtually every day of the year despite a speech impediment, or the person who makes snide comments about the way that person speaks without so far as I know ever producing even one video in that oh-so-perfect voice of yours?
And by the way, some of us actually like his voice - we don't all have to be the same.
Stop the harassment.
Either you let it get under your skin, or you get used to it after a while. The subjects of his videos are too intriguing for me to not listen
Don’t watch then you won’t be missed.
Have you heard of anything about the fault SE of Yellowstone that's opening up? I keep seeing shorts about it.
