Been almost a year now since this session was posted so I don't expect you to see this, but just so you know, too many people have decided not to listen to science but that doesn't mean NO ONE is listening. SOME of us are listening, and I'm one of them -- and I'm trying to impart the same knowledge-based science on anyone willing to listen. And when they won't listen to a layman I refer them to your channel. SOME of us are listening.
Been watching for the past few weeks now. One of the best things that came from Covid it seems. I was in the healthcare trenches and this awesomeness was being recorded and saved. Glad I can enjoy it, thank you Professor Nick. It brings me back 20 plus years.
Nick. I am 77 years old. I enjoy your videos. I have learned so much about our earth from your videos. Me and my sister vera watch you videos and in class. I told my sister wow we are in college class even if we are a fly on the wall. Feel your energy your passion in what you teach.we watvched z lot of history unfold in our lifetime. And reports of earthquates and Mt St Helens eruption. In 2001 I was in the earthquate that shook Portland Or. And got to watch Mt St Helen begin to wake up and start building a cone inside again. I feel very lucky to have got to be there. Back in Florida we do deal with hericanes. My friend took be down the coast to Yahats. Along the coast down there were signs warnings of tsnamias. Wow again. Thank you for your lectures and opening our eyes to our land. Foevrr grateful. Me and my sister remind each other your coming on..thank you nick. For enriching us two country bumpkins to a greater knowledge. Hugs from florida
I got in big trouble when I was a member of the COC of a Oregon coastal town and tried to publish a brochure on tsunami escape routes. The biggest obstacle: Emergency services... I now live in the Blue mountains of NE Oregon.
*DON'T WORRY ABOUT THE BOOK,* Nick. Your almost daily streams dating from March, 2020, tell a better story and it's a "gem." Keep doing what you're doing. I can't thank you enough but ... thanks.
good you got the lesson BACK up, though for everyone... wow, sure wish you could get a special teacher permit, to keep sharing those great teaching videos that are used from OTHERS that have and do, help us so very much... we love your lessons, so very very much, nick... keep up the great work...
I absolutely love Nick’s humor!! 🤣🤣🤣🤣 He makes everything fun to learn. He apologizes for cussing....I love it. It’s not a typical teaching style and helps the information stick. 💯♥️
I have been taking note each class and if there is a moment that makes me chuckle or peaks my love and appreciation, I add a note to my page for each lecture. So for instance, last lecture, I wrote " was gifted 2 pointers, one 25+40years old and cried".... that's me crying of the love and generosity, not the tears he fought back.
I am 77, and I am so grateful that I happened upon the magnamious work you are putting out into the world to bring this science to us the people who never got to go to college. I love the pbs specials you did, they were awesome. I tell people about you all the time, Some of the lectures I have to watch over and over, as I cannot remember as well as your students. anymore. My sincere thanks I appreciate what you are doing so much. You are the most dynamic teacher I have ever witnessed in my life. A forever fan. Maxine Martin Erickson from Lacey WA,
Rewatching this class during my teaching break between school years. Learning a lot more this time, with all the note taking and hard studying. Thank you again for your work.
At 1:25:00 Nick talks about people pushing back against science and not believing science. The world I live in surrounded by farmers, ranchers, truck drivers, construction workers, etc. they feel beaten over the head with people pushing their political agendas telling them they are terrible people in the name of science. The thing I love about Nick is that he looks past all of that and reaches across the isle to just teach science. No agenda. No judgment. Just pure science. He’s a good dude. I don’t believe we should put people in boxes at all but for the sake of this comment the “science camp” and the “[insert right wing stereotype] camp” need a lot more people like Nick Zentner.
Thanks for sticking to it Nick. Even if people may be "science cautious" I believe having someone fun and relatable like yourself can open their minds a bit.
Yeah, I blame the media for creating a wedge between two political agendas and participating in that disgusting practice instead of doing what they're super to, witch is staying neutral and educating the public, as Nick said, "we live in dark times" it's really sad that science has been hijacked by politics.
My husband and I live in Hillsboro Oregon. We have visited Yakima Canyon twice. We have been watching GEOL 101 lessons every weekend. With the 3-day weekend we have caught up all lessons. We enjoy your teaching, learned a lot. Thank you very much! I am so glad you have gotten vaccine dose 1. I have had 2 doses. Just want to let you know the day after dose 2, you might want to take it easy (I had fever and headache). Wish you the best!
Stumbled onto your lectures by chance (back yard and 351 series) and after a dozen or so lectures I decided to audit your Geology 101 lectures after the fact. I'm currently on #22. At 74 years old... well lets say that I've been fascinated with topography for a long long time, having traveled through every U S state numerous times as a member of the US Army Field Band. I've climbed about 25 minor peaks during those 26 years, only a few with technical gear. Always wondered how and somewhat when these ranges were made and your series has taught me much about the how for which I'm very appreciative. I intend to finish the 101 course and then return to the vast videos you have shared. Background: MI native, BME Central Michigan University, taught music in two MI school systems before enlisting in the US Army (26 active duty years). Overseas travel to UK, GER, BELG, FRA, LUX, INDIA, JAP, SKOREA, MEX, CAN (so many times). Enough! Back to lectures.
I fell in love with the Pacific NW when my brother moved up there for work. It's my favourite part of America. These videos have added a whole other level of interest, partly sparked by Hokosai's 'orphan wave' prints. Superb lectures, clear explanations and, as a former teacher, it's great to see there's still a place in university for the humble chalk-board.
I imagine there were a lot of victims from rock/landslides, river/creek flooding, trees falling, and so on as a result of the 1700 Cascadia earthquake.
Love this one and the next, being an avid beach visitor, it is a terrifying thought to experience something like a 9.0 earthquake at the coast, and the tsunami that follows. I did watch a program on an Oregon shipwreck that has an interesting connection to the tsunami in 1700.
Thank you so much Nick for your excitement and energy during your lectures. You have me shouting out answers and yelling in excitement myself during these classes. So fucking- sorry Patrick- fascinating!!!!! I'm from vancouver BC, and yearning to visit these geological spots you share. Hopefully one day!
Is it possible that the Yellowstone hot spot has weakened the crust enough to cause it to slightly fold and twist? Like taking a knife to a piece of cardboard so it bends where you want it to. Once this started, it formed a weak spot that it, basically does not heal, so stays weakened! Had to leave part of the way through it today for a meeting.
IF THERE IS CRUSTAL COMPRESSION IN WASHINGTON DUE TO THE ROTATION OF THE LEADING EDGE OF THE CRUST, IS THERE ALSO SOMEWHERE DOWN SOUTH WHERE NORMAL FAULTS OCCUR DUE TO CRUSTAL EXTENSION? EDIT: nevermind, my question's been answered at 1:15:00 . Thank you Nick ( and Dave for asking the same question ;) )

Greetings from Germany. Nice lecture. Checking Brian Atwater now. Interesting to realize that we are still missing lots of knowledge regarding seismic topics. Do you know "dutchsinse" and his ideas? (On YT)
Thank you for the opportunity to see these great geology classes, I am immensely grateful to you Nick for everything I leart from you in my amateur geology discoveries. I'm also very grateful for the geologist community whom discovered all these wonderful secrets about our planet. I really wouldn't like to be just buried like dinosaurs which are popping up from melting permafrost, to die dumb with food in our mouth. I'm not accusing them, they were animals whom managed to live as God created them to live, but we humans we've got brains and the ability to think, plan, act. What is sad - and not only in your profession, where I have to tell you that even for me is obvious that we are fed with lies, I mean let's look at the case of Turkey where earthquake of over M7 occured this year, 50.000+ casualties. They say you can't predict earthquakes. I say there was earthquake monitoring system in place over there, and they were well aware of the quality of the buildings. The way things are going in our world is disgusting. I'm learning psychology for example. We have plenty of scientific evidence for what is creating sickening stress for people, of toxic leaders, toxic political games, and noone cares about doing something. Or when they do, that doesn't help either, it looks like certain shit, certain behaviour, certain status quo you just can't change. So my friends, - the crazy lady with a long comment warns you, - it's more probable that the alternative theory is true, which is described in the sci-fi comedy Iron Skies, that our world is led by form-shifting reptilians, and that we live in a simulation where we work down thousands of lives of karma virtually. Otherwise this whole thing doesn't make sense, that humanity acquired so much knowledge and the only answer is to shut up and suffer. According to religious predictions, buddhist for example, we are in for a long period of worse times. According to Christian explanations it will be worse and worse till it will be better when Christ comes back. So we are glad we know that much, and there's still not much to do, isn't it? Not much more than inform where it's possible, for what I'm very grateful! I'm still happier to know it, I would hate to stay in darkness and not know the reasons where all the suffering is coming from, and without seeing clearly whom are responsible for that and what more could have been done. Well, I guess we all can do better, we have to go up to the limits of our possibliities and sometimes beyond, when it's needed, for our fellow humans. I just can't agree that we are too many on this planet. There is plenty of place on this planet, I travelled enough to know it. There are too big egos, whom need more space, money, resources, whom really think that they are entitled for more than the rest of us. I believe that the maximum numer of incarnations on this planet is due to the fact that we all wanted to experience these very special times in Earth's history, and probably from to point of view of karma to get the chance to connect and sign off karma with as many people as possible. Good luck for all of us, Namasté.
Are you going to cover how far in-shore the Tsunami reached? Is that known? It's my understanding that the Tsunami reached the Puget Sound from the WA coast.
Do these tsunami hazard maps show the coastal areas as they currently exist or how they'll be after they drop the number of feet estimated when the Cascadia fault slips? I'm assuming it's the former as tsunamis can come from many sources. Perhaps some specialized maps could be created to show the actual increased hazard from a CSZ event.
Do the GPS receivers show the tidal influence?? Is there a map of the coastal dropping? What is it really in different places?? Not 6 feet down everywhere at coast, obviously..., also, sand sheet thickness??
Just joining your class now. Wow Always Loved Geology. A note to your young Students. My question is this. Do you have one or more, perhaps even several future protégés? If I was a young student again I would be fighting to be the Loyal number uno, to accept the torch from you Sir, to carry on this important science. We need to take the Seattle faults early stages of discovery much further! Indeed all Geology. We need your passion to take this the next 40 years.
I first studied geology in the early 1970s, then geosynclines were the reason for depositoinal basins, I sort of want to try and believe in that tectonic reason for tectonics
Thank you for making these intensely interesting geology lectures available. I live in a region of far Northern Calif. that surely is on that clockwise rotation. Want to know more about GPS sensors in our area if any. As to science deniers, I would say it is early days yet. Reality has a way of dinging the thickest skulls eventually.
A thought struck me while checking on the Google Earth globe, to get a better picture of the Pacific undersea terrain while following your lecture: Is there a complementaty anticlockwise rotation of plates south of the equator in South America, Nick. Maybe, on the geological timescale, there really is 'weather underground', and the lithosphere may behave like the atmosphere, but with a circulating magma cycle, from rock to lava and back to rock, and buried and back to magma and to lava again, taking the same function as the water cycle, does in transfering heat energy around the globe in the atmosphere. Maybe the forces driving the plates are actual weather systems powered by radioactive decay, and the plates revolve like low pressure winds, and the spreading centres and hot spots are the high pressure areas (the Earth's pressure relief valves balancing the expansion due to radioactive heating, against the forces of gravity and Corriolis). Gotta be worth a thought!
Someone asked how deep the rotation goes, and that made me think the question could be answered by a study of seismic sections in the area. I thought such sections might reveal the presence of listric faults (i.e., faults that gradully become less steep with depth) that could be associated with the rotation. Has anyone done a study like that?
I love your lectures Nick! So, when the rotation of the crust runs up against the block in B.C., what happens? Where does the crust go? Up, as in making mountains? Subducting? Or did I miss your explanation? Curious.
Unfortunately I live in Victoria .... maybe i should move. It would be cool to see the mechanism behind the shallow quakes on Southern Vancouver Island.
Hey Nick on your RU-vid copyright strikes. You might be able to fight these if you take the right approach. Head over to Rick Beato's channel where he recently worked through some issues regarding use of music. Basically if you get the "owners" permission ahead of time you can push back on RU-vid. . If not it would be great if you or someone could put the links in the description you were going to use. Thanks for all you do.
I live in Hood River and when I look north on the Columbia River I see a lot of syn/anticline evidence. Yet none on the Oregon side. Is this the southern part of the OWL and the Columbia River is its southern boundary?
I'm confused by your vector arrow on the Juan de Fuca Plate. It's pointing in a northeast direction, almost parallel (not perpendicular) to the Juan de Fuca Ridge divergent boundary. From this, I'm inferring that your arrow is relative to the North American Plate, rather than to the Pacific Plate, but does this mean that the divergent boundary itself is moving northward?
WHEN I WATCHED YOU MOVE YOUR HAND TO DEMONSTRATE THE ROTATION OF THE LEADING EDGE OF THE CRATON, I COULD IMMEDIATELY SEE THAT THAT WOULD STRETCH THE AREA AROUND NEVADA - IS THE RIFTING DOWN THERE ALSO A PIECE OF THAT STORY? DOES THE RIFTING HELP TO PUSH THE PACIFIC NORTHWEST NORTH? OR DOES THE DRAGGING OF THE PACIFIC AND JUAN DE FUCA PLATES STRETCH OPEN THE RIFTING IN NEVADA?
Has anybody alluded to the idea that we're seeing mountains growing as a result of the clockwise rotation and the uplift that is occurring with the coastal subduction?
I wonder if there is evidence of tsunami activity during 1700 in the history of the Asian countries that might also confirm the big earthquake on the power coast.
Yes. It is documented in Brian Atwater's book, The Orphan Tsunami of 1700, 2nd ed. It can be downloaded from the USGS website, Professional Paper 1707.
I assume they have tsunami warning at the mouth of that Vancouver Island straight there is 30 miles of warning before it hits Victoria and other coastal suburban gids. The shake like you never experienced would be an immediate warning to drive to that high ground before the roads get congested. If the forest died and were not taken out by the wave, it would have to be deep enough soil to support a shallow root tree that dropped into the ocean, the trees described cannot live off of salt water or having submerged roots. Anything exposed to oceans and close plate boundry should be assumed to be a tsunami zone and things like nuclear power plants should not be located there is common sense, as for a home, business, or school it is a risk but if you are aware and have an evacuation strategy, not when the government tells you but after being shaken, you should be OK. In Japan there was plenty of time to head to high ground after the shaking, the 5th floor of a high-rise with its foundation under attack, taking pictures of the flood, wouldn't be my choice though, it's better than being in the streets, I guess.
Hi Randy. Nick covered slow earthquakes in Ep. 46 of his 'Nick from Home' series. If I recall correctly, he had one of the specialists working with the GPS data in his garden, explaining. I think the subject is a bit too esoteric for a 101 class and not well enough understood to present in such a venue. You may have to go and watch the episode from last spring.
@@bagoquarks Don't know, Michael OBrien. I have inserted lots of non-RU-vid links in other RU-vid comment sections, including Nick's (e.g., my reply to a comment in yesterday's class comments). I have heard one cannot insert a link of any kind into Live Chat.

Really great examination of the facts. So many facts new hypothesis could be made from the scraps of the observation's. ya the geology here is "wierd" the Yellowstone hot spot went right under there those cinder cone's there deep plumbing could have been laid by that event. This is worth watching more that once. One of the more intresting and thought provoking things I've ever watched not kidding. UH ya money right now I have to take a cheap digital caliper and graph It to a linear slide like an arduino shield and add a single chip logic level converter that can switch 5v to 1.8 Ya the "politisssiiissssm" and science hate? your reaction to that. YES! thousand words you want em all I got em in me Its a rage. Imagine hot lava pouring out of some one's head, While just gonna say the original planet of the ape's is where we're headed Oh of topic science curiosity the O-H radical and its power to damage Mitrochrondial ? spelling DNA on the surface of a virus the charge in a dust partical is remarkedly the same and you get your raindrop!
This sand obviously came from the ocean, where did all those many sand-blows come from at the New Madrid Fault earthquake, at least a Thousand miles from the Ocean.
"Uuum Teacher?" With all due respect, if the Pacific Plate is migrating relatively Northwestward from the Juan De Fuca (JDF) Spreading Ridges, and the Ridges are diverging 180 degrees evenly on each side on a NNE-SSW axis, then how can the JDF Plate be "migrating Northeastward" as is being taught? I respectfully submit to you the high resolution sonar images that show there is no JDF Plate oblique departure from the JDF spreading Ridges, and the Transform Faults (Fracture Zones) delineating the JDF and Pacific Plate migrations relative to each other are in a WNW-ESE orientation confirming that the JDF is indeed migrating ESE, not NE. earth.google.com/web/@41.67094622,-125.97602297,-288.91795869a,645325.88434562d,35y,358.95949838h,0t,0r?hl=en earth.google.com/web/@45.41715752,-125.97105665,100.09462618a,644936.83888391d,35y,358.95949751h,0t,0r?hl=en
A little off topic from your post, but I noticed some interesting features in those links. I wonder what's with what looks like rivers heading out all the way to the middle of the pacific plate?! I went looking for more and found some in the Bay of Bengal and off the NE coast of S America that are curved like meandering rivers on land and you can even make out oxbow "lakes".
@@brandonholt6717 Hi Brandon, Those are Turbidite Channels; the sediments falling nearly 9,000 feet off the Continental Shelf gain enough velocity to travel for hundreds of miles on the sea floor. They’re also used heavily in the geologic record to determine an outcrop’s origin.
As a San Andreas fault denizen in central California I'm rather skeptical of Atwater's claim of "tsunami sand" in regards to this layer being deposited by the tsunami wave. I think a much more plausible explanation is that this sand came from "sand boils" ("sand volcanos") which are very common during earthquake triggered liquefaction events in this type of coastal terrain. Sand boils go hand-in-hand with local subsidence. I don't doubt that tsunamis are being created by these large earthquakes, just that a sand layer may not be the "smoking gun".
@@Ellensburg44 thanks for the link, I had only minutes before found it w/Google. Great book BTW! In it Atwater mentions "They also found that the burial began with sand delivered by tsunami or erupted in response to shaking" so he does acknowledge the sand boil possibility. But tsunami or the next winter storm? I'm not seeing how Atwater can be so sure. (This great quake was in January)
@Paul Liebenberg: The element you are missing is the tremendous tsunami energy that allows them to go a mile inland. You don’t get that from a winter storm. If winter storms produced sand sheets then that evidence would be present in the tidal mud layer above the 1700 deposited sand layer. Also remember there are plant and tree remnants in the layers that can be carbon dated. And also the tree ring dating.
@@paulliebenberg3410 Paul, with all due respect, I don't see how your opinion is equal to one of the best scientists in the world. He has been studying these sand sheets globally for decades. Have you?
@@Ellensburg44 jeez my opinion ain't worth squat, just trying to supply some healthy skepticism. FWIW the Puget Sound tsunami sand looks like something compelling, the Cascadia examples just don't look right to my layperson's eye.
Your science is genuine, unique, amazing. Love Brian Atwater. But people don't appreciate being mandated/coerced to be part of an experimental vaccine program, even if such experiments on populations are "science". Science is not an acceptable excuse for abandoning ethics.
