Hydrothermal swarm activity is misunderstood by many folks ... immediately thought as "imminent eruption." Never considered to be caused by other geologic dynamics of a volcano. I would even venture to say Campi Flegrei is the same situation. Once again, thanks for the context!
Mt Shasta had earthquakes like these right before St Helens blew. They expected Shasta to go up. Evacuation plans were made for Mt Shasta city, Weed & McCloud.
one of my favorite parks to explore and camp in....trout fishing, steam vents and the climb to the top is awesome.....also the area is gorgeous........the summit is not hard to hike to....if you go there, explore Bumpass Hell....
In 2017 I camped at Deerlick springs and the property owner took me to a bluff where I could see Lassen across the valley. I love that area and hope to visit again one day.
My dad worked testing soil and water for radiation levels.he often had to put evacuate orders on the town of weed. He worked for the fed gov bureau of reclamation central valley water project/calif.... I seen some awesome places up around Shasta that not too many knew about. Waterfalls in different brilliant colors. The rock and dirt color is different all Ng the way so the waterfalls are all different. Most peesdont know about them. Or if they do then they don't know or can't access them. Hint fly fisherman will try to venture back there ......❤
From what I've heard similar swarms in that area of the Cascadia fault are common, happening about once a year. So probably no need to be more concerned than before.
@@b.a.erlebacher1139 I grew up near the Cascadia subduction zone. You may have heard that the swarms is common you have been mis-informed. They do not occur yearly. I suggest you do a history search on the USGS site for that area to become more informed.
@@Skidderoperator The Sierra's are a plutonic batholith and have no active volcanic properties. 20-30MA, they were a part of a Southern Cascade Range before the Farallon plate was subducted. Since Mt. Lassen's magma chamber is fed by the Southern Gorda subduction and the Gorda is a subplate of the Juan De Fuca plate system, Mt. Lassen is indeed the Southern volcano of the Cascade Range, not the Sierras.
@@johnnash5118 Yeah there are no volcanoes in the Sierras proper. Though to my knowledge the magmatic intrusions responsible for the Sierra Nevada batholith were predominantly Cretaceous in age with Pluton formation ending 70 Ma. Traditionally it has been explained as Farallon Subduction but based on the newer research discussed in Nick Zentner's A to Z Baja BC series it appears to have been part of an oceanic subduction arc where the North American passive margin was being subducted until the oceanic crust transitioned to increasingly buoyant continental crust which was too buoyant to subduct leading to a process called slab failure which involved a huge influx of magma filling in the position of where the subducting slab broke off and fell into the mantle ultimately leading to the former volcanic arc becoming welded to the North American continental shelf as has happened or is happening in New Guinea and Indonesia with the Australian continental Shelf or Taiwan with the Eurasian continental shelf. Eventually you would have had slab polarity reversal such that the Farallon plate as it is known would be the subducting plate rather than the overlying plate the bulk of Pluton formation is slab failure melts which are chemically distinct from subduction melts much richer in several elements including Strontium and Yttrium?, if I remember correctly. I'm not 100% sure on the 2nd element but Strontium abundance is one of the hallmark characteristics of slab failure melts. Regular subduction melts don't lead to enough siliceous melt intrusions to build a proper cratonic crust composition batholith only the subduction of a continental margin and subsequent slab failure as the subducting slab detaches due to the density differences can do that. I.e. typical subduction batholiths have too large of a fraction of intrusive mafic melt components to truly have a continental like buoyancy and they also occur at different depths and distances from the trench. These conventionally have been explained as a change in subduction angle but this fails to explain the chemical differences in magma composition as well as the more shallow, but still quite deep, depths of the intrusions and the orientation of parts of the Franciscan formations. The uplift and unroofing of the Sierras was indeed centered between 15 to 30 Ma as part of the Basin and Range uplift with the batholith having been deeply buried prior to that time long after subduction ceased in the early Cenozoic.
It's a great drive/hike. You can drive right up to a couple of the mud pots. Then there is a short hike to the ones at bumpass hell. 10/10 would recommend.
Also recommend, pretty underrated compared to other California NPs. Fun scenic drive, also recommend Burney Falls and Subway Cave nearby as a short stop!
I live up here in Redding about 30 miles or so from Lassen. My thoughts have been that with all the hotpots, femurals, etc release whatever is building up underneath.
They talked about it on the news here. Some geologist was saying it was in an area where 3 plates or faults converge, but it did not sound like an area where they expected a hug subduction quake to come from.
Thank you for your swift posting of events around the world that have concerned people or piqued interest in the World. I really enjoyed the last video about Stromboli, I am amazed that so many humans live there, since Stromboli is so active, but I assume the activity is not threatening the town, so... I want to visit there one day!
I grew up in the valley right near Shasta and Lassen, always preferred going to Lassen when it got hot in summer. Lassen national park is gorgeous, and I've got lots of fond memories of spending time at Hat Creek and checking out the lava tubes.
I remember the prelude to St. Helens, but in that case they could see the ground bulging up too. If the geologists also saw their tilt-meters indicating something like a big magma bulge rising under Lassen, I guess they would be more concerned. People know a lot more now than they did back then.
When you mention earthquake magnitude are you using the Richter Scale vs Moment Magnitude Scale? Perhaps you could do a bit explaining how they differ and which you use and why, etc? Thanks for your work. Cheers! More on the Cascadia area swarms too please.
I've been curious about the cause of the earthquake swarm east of Clearlake California. It's seems as though the earthquake swarms in that area never end and I haven't been able to find much information about it.
It's usually counted as the most southerly peak of the cascade range, as the geology better matches that of the Cascades than of the Sierra Nevadas (which are mostly uplift mountains). The gap that CA-44 travels through does give the impression that the gap is the end of the Cascade range, but that's not really the case.
We just had a very large DEEP quake off So Philippines, followed fairly swiftly with a large quake off Vancouver Is with larger 4s and 5s aftershocks... So the energy wave continuing down through or western volcano chain makes sense- and releasing in small quake swarms vs bigger fault shifts is a Good Thing imo
Perhaps you might be able to answer a question I have regarding the measurable quakes that seem to happen almost every day in west Texas. Why? Is there an active fault in that area or is it a missle test site?🤔
That drive up to MT lassen and further old station theirs cave campground rushing creek waters hiking fishing then up to Burney falls theirs a lake with waterfront camping swimming.the most beautiful drive the beautiful trees all of it.spring and summer the best.winter great if your into snow.wanna go back.
@@TheDanEdwards and all of the x class solar flairs and the CMEs, charging the Æther causing all of the motion from the quantum to the planetary to the celestial to the galactic. Nested fractal harmonic iterations of itself isn’t not irrelevant. Wireless induction of power aka the photo electric effect of light is not irrelevant. It’s the only game in town😂
None. Rock is a great insulator, so heat from any subsurface magma doesn't make it to the surface -- those magma chambers are way too deep. You would need an actual eruption during the summer for any chance of a forest fire to start due to a volcano.
Not necessarily magma rising, but rather the presence of a magmatic system at depth. To have geothermal activity you need a source of heat, lots of water, and geological conditions that allow for the water to circulate. Places like Lassen and Yellowstone and The Geysers have all those elements. If magma were rising, it would be driving off all that water, and there would be clear changes in thermal/gas emissions and gas chemistry.
As you've a very specific channel to Volcanic activities & earthquakes; really appreciated, surely it's in the benifit of human tribe as an overall. I've a question for you (it's address surely could open some more aspects of thought process for you to enhance your capabilities to perfection to more serve the mankind regarding these potentially destructive disastrous crust phenomenae e.g: volcanic activities & earthquakes). Question is ; Do any relationship (including evolutionary) exist between fresh magmated hard masses (usually brittle across the varieties or timelines) & hard stony mountainous rocks. Further in the subject of "rocks evolution" Do these magmated rocks converts to stones/rocks/or mountains Or these both are 2 different subjects for ever ; ( a:Lava-ted Rocks b:Stones/Rocks/Mountains). Anyways ; Both cases are not strange at all ; either the evolutionary clues have been provided / or not been provided in the nature , Further the stones/rocks/mountains have any evolutionary connections to magmated rocks (lawated rocks) or have been created differentially as such , or they have lost/blurred the evolutionary connections. All Praise To The Creator Almighty ❤❤
Welcome to the party.. I've been trying to get people to look east. From fresno ca. For the last 13 hrs. It started with three small sitting clouds. Now look to our east. And west. ..
@@b.a.erlebacher1139 I’ll try it on you friend: lassen is not a threat, Mt Shasta is the one to be concerned about if one worries about eruptions, the failure of the Shasta Dam would destroy the Central Valley. We witnessed the destruction caused by St Hellen’s due too melting ice and snow, the snow pack on Shasta is much greater.
You almost lost me when you started talking about Yellowstone, but nothing you said about it was wrong. Most people who talk about the Yellowstone Supervolcano are repeating inaccurate or outdated information they heard elsewhere, and need to do their homework and find the latest information before making a video on the subject. I congratulate you for doing that. However, and I hate to say this because it sounds rude and that is not my intention at all... You need to work on your "video voice." Your data is accurate, but your delivery sounds like you're reading the minutes of a board meeting or something.
This is science. Science don't care about meaningless things like that. Watch the news if you are that shallow as he can't help his voice due to disability
@@b.a.erlebacher1139 it's perfectly respectable feedback, and sometimes that's how people grow and develop 👍 and if he wants to keep the voiceover the same that's completely fine
@@earthlymatters888 he's explained this several times. He scripts his videos to keep them short and speaking like that when reading is fairly normal for someone with autism. Expand your narrow mind to other possibilities.
You insult the creator of the videos and demand he change to suit your tastes. Do you know how to get along with people? Entitled much? Btw, ALL-CAPS is considered rude.
GH makes these videos and narrates them and provides them to you for free, but you feel entitled to insult him for his voice. He's a geologist, not a voice actor. If his voice bothers you, mute the sound and read the subtitles.
He's a real human with feelings and maybe on the autism spectrum. He's a nice guy and I like his channel, and I like his voice. Go away if you can't be nice.
GH puts a lot of effort into providing these videos to you for free, and all you can do is complain and insult him for his voice. Entitled much? If the voice bothers you, mute it and read the subtitles.
