That was really touching. That special 'gift' pointer from the other professor is a real honor.

Prof Nick, you are amazing!! I swear to god I’m a 53 year old with a job, family, responsibilities and all I think about is the next lecture and damn it your quiz and mid-term comments make me nervous 😂!! Like so many, I so appreciate you and your teaching! You are damn good at your job!

You are loved, Nick. Cheers from Tampa.

*CONTINUITY:* A 65-year old pointer starts the third leg of what we hope is a very long and rewarding journey.

I've watched all classes up to this one, and I will watch the entire class. Great education by a master!

❤ love you Mr Zentner! And thank you.

Hey Nick, just catching up. These impeachment hearings are sucking me in just like the Watergate hearings did almost (gulp!) 50 years ago -- when I was a young university student. About today, you were on form. Your presentation read like a blockbuster thriller; you blew those young geologists away! (Spell check replaced geologists with apologists.) Great job!

*sigh* the car antenna. Oh, i cannot express the nostalgia that flooded into my head & heart on seeing that particular bit of Automobiles Past! Also, the pang of regret that jumped up to remind me of my misspent youth, committing random acts of hooliganism, just because i could. What an idiotic guttersnipe i was. And lived to tell the tale!

It truly is the passing of the baton in learning race of life. A real relic to be treasured. A touch stone if you like

Thanks Prof Nick. Wonderful.

I drive home through the Issaquah Alps all the way down southbound through black diamond and Enumclaw, to South Prarie, Eatonville, Morton, and finally west on US 12 to Chehalis, where I live. I work in construction all over Seattle, Bellevue and Sammamish areas. It is a much nicer drive for me than I-5 and is consistently the same amount of time getting home.

Love how this is coming together. Thank you Nick!

Two pointers! One for home, one for the classroom.

Driving to Washington from Idaho in 2019, our first stop in Washington was Puyallup. We spent a good portion of the trip practicing how to pronounce it! Thanks for the memory, Mason.

Having grown up in Southern California, old enough to remember and exprience the 71 Newhall - )than in Whittier; relocating in 83 southeast to San Bernardino Valley) 86 Palm Springs/Desert Hot Springs, 87 Whittier, 92 Landers/Big Bear and 1994 Northridge quakes my prediction and pattern of quakes are: Every once in a while mother nature gets annoyed, deciding to slap the ground or Mother nature needs a good stretch. Have a grand day!

Excellent presentation, g'day from Australia.

At 1:10:00 you had me literally dropping my jaw, and shouting WHAT? at the screen.

Actually read the term 'hanging wall' in an historical fiction novel about gold mining in Southern Rhodesia. I got it ! Thanks Nick.

A big man with a big heart. ❤️

Need a class fight song to liven the group up! Something with Vinnman's Bakery, Yellow book, F-bomb, and a sorry patrick!!

Yet another maestro inherits the "tools of the trade" from the distant past. Now all you need is some decent non-crumbly colored chalk and an American-made chalkboard eraser.

1- use the brio - it's a better camera 2 - what you might find useful would be a blackmagic ATEM Mini switcher if you ever decide to go 2 cameras or so - Thanks for all your good work.

I used to live at Fort Lawton (now Discovery Park)! I could see where my house was! Nice to see it again! And, I worked in West Seattle (when the shipyards where there).

At school we used to have some neat little mapping puzzle books, where pages were maps of strata in increasing levels of displacement complexity. Given a few dip and strike marks, one would have to draw paralel strike lines in, and get the outcrop pattern from where they intersected the geographical contour lines. We used to enjoy filling in these books even when we didn't have them as homework! Nick's students would develop their 3D imaginations with the aid of these books, if something like them is still around. (Actually, back then, even at college, geology was mostly something of an art lesson, than a science: if you couldn't produce perfect pencil illustrations of trilobites and graptolites, and draw convincing tetrakishexahedrons on cubic axes and miller index all the faces, you weren't going to get very far! I liked the drawing at school, but at college, it just felt like time wasting, so I just cut up my school books and used the same illustrations again! No daily field trips to be had in geologically boring, built up North London UK, by bus! :)

Great question in Q and A about which side of a fault moves. Nick said both. Keep that in mind wen he talks later on about the Japan and Boxing Day sunamis. It has great relevance in explaining why both sides of the rupture generated sunsmis in opposite sides with the wave crests being 180 degrees out of phase. There is a great KZfaq video that was made as part of the final international commission into the Great Sumatra Earthquake, its causes and recommended responses. Including the extension of the Pacific Sunami warning network to include the whole globe. I can go to it further on Discord if people want.

That was awesome!!

Excellent class!

Truly enjoy your no filter deliver Don't change

Just moved to Ellensburg. Keep up the good work!

Love the pointer story from Professor Subatai. If you're in the comments what did you teach for 40 years?

“Sorry Elizabeth from Tacoma” 😂

Someone in chat asked about getting a yellow book, in the first two classes; Nick had a pdf in his comments so townies could download it.

these lectures are wonderful just wish there were time stamps and that the beginning was cut 😊

The size of the tsunami caused by an underwater fault rupture is tied to the surface ground movement I would think. If the fault moves 30ft vertically and the hanging wall is measured to have moved 10ft, the tsunami would be smaller than if the hanging wall moved 30ft.

Watched again after live. There was a small event on the Seattle Fault involving Meydenbauer Bay in Bellevue when I lived there as a kid. The water rushed out of the bay ( flowed south) exposing the bottom, then filled back up again. It was reported in the Bellevue American weekly newspaper some time after 1957, and before the late 1960’s. Pretty sure it was before the ‘65 quake. Before they knew about the Seattle fault. Now I just need to find out what roots the Natives were digging for other than onion and camas (third root).

1980 is pre-Narvana. Closer to Van Halen time.

Good lecture. Thank you.

I forgot to mention in my previous post that the teacher who ran like a scared hound, knocking students out of the way in order to save his skin was the oldest teacher and as frail as could be It took him ten minutes to get up the stairs to religious class. It took him about 30 seconds to escape the hallway!

Why is there a sunken forest off the south end of Mercer Island?

@Nick Zentner So the rotational direction is west northwest or close for my question. So if we have rotation pushing away from the costal region (or over the costal region) Then where is the point going east exposed if rotation is to the west? I am thinking it is the old subduction zone in Idaho or farther south ? If the rotational plate is rotating outward off the coast would there not be evidence of a pulling away from the old plate boundary? Maybe this is a stupid question...

Wow

Thanks

I guess we know who's supplying the refreshments for the end of Quarter kegger. Young Mr. Widmer? I kid, I kid :P

You rock nick

So was there a 3-1/2 meter drop on the North and a 3-1/2 meter rise in the south making a total of 7 meters thrust fault? Also is there an ability to date the uplifted areas of the faults to get an average date interval?

KZfaq, not nice! Give Nick back his most recent stream!!

So who exactly is Patrick? Where can I find the story of Patrick?

Our last week`s Magnitude 7.1 one was like your deep slab snap one

Vinmans bakery is growing subscribers!

Vinman's now has 240 subs.

Second question: Could the Northerly migration of the "Pacific Plate" (which may be the Salinian Terrane/San Andreas Fault) @the Mendocino Triple Junction be driving the NW Rotation instead of the JDF Plate as stated? www.csufresno.edu/csm/ees/documents/facstaff/wakabayshi/publications/MooresEtAl1999.pdf

I was so moved by the moment you got the pointer

Nick, are these faults one and done? Or do they repeat at some point? Is there field evidence to tell us that information? Keep up the good work and stay healthy! Diego from Eugene OR.

Talk of 'hanging wall' always throws me off, because my mind automatically assumes it refers to one wall hanging off the other. It is interesting to learn of the surface from which miners hung their lamps, but it is easier to mentally picture the effect of compressional forces on a fracture plane without the mind being diverted into picturing 3D miners. [At school back in the '60s, teacher Roy Morris, was a popular figure like Nick without the electronic and video aids (only tape recorders and an occasional real of worn out borrowed film then!). His globe was a spherical blackboard on a wire from the ceiling, that Nick could usefully add to his chalk boards. One is used in an ancient YT clip of an early explanation of 'continental drift', that even has movable continents. We used to have to do a further 3D mental exercise of determining if faults 'haded with or against' the dip of the strata, which miners would need to know in order to dig in the righ place to get at the displaced target bed. That was even more of a brain twister than imagining hanging lamps from surfaces long eroded away! :) ]

Nick, I'm coming to this vid two years late so I'll understand if you don't see this; BUT.....my question is, is there any way to know how much of the thrust-fault movement on these faults in Puget Sound can be attributed to *_glacial rebound_* as opposed to strictly crustal compression?

Was it after this video was made that it was discovered the Pacific Northwest is rotating clockwise?

Are all these faults related to the older fisures?

53:11 .. I really got confused over the hanging bit and the blocks. Quick question ..would the Tsunami have hit Oak Harbor?

Please steam the midterm exam.

Video watch Renton, WA 10/01/2022

you tube blocked cascadia video. what?

Curious to know if there's any reason why the quakes logged over the past 150 years all happened in PM, not AM... Any cause? Or is this just a list of quakes in the afternoon? at 31:21 kzfaq.info/get/bejne/pqpyiZdizd-Yh4k.html

Starting to realize that Mason is a legend in your classes! lol.

STUDENTS........Show up tomorrow

Is this happening again tomorrow?

Pasco Washington

I would like to learn 'till I'm eighty.

You’ve done several talks on the Seattle fault, enough where the students in your class here are not interested in knowing that their lives, possibly, suddenly being snuffed out. Hard to wrap their attention around?

Hey nick,copy right trolls might've gotten to your work, when I try to watch your lecture on the cascasdia earthqaukes I get this message "Video unavailable This video contains content from A+E Networks, who has blocked it in your country on copyright grounds." I'm in the usa, pretty damn sure you've got nothing to do with that network.

American copyright law abuse can be tied back to legislation introduced by friggin Sonny Bono ... as if he had more than 2 brain cells ... it's another extension of the racketeers.

Nick: I'm no materials testing expert, but I did work in a testing lab for a while, and it strikes me that, when you are teaching about faults, it might help students visualise fault planes, if you play them some video of tensile tests on sheet materials, so they can see that the stresses usually resolve to a 45 degree break, which may be equivalent to the plane of a fault. Because of this, it is unlikely that they would find many faults other than strike slips where the fault plane was at 90 degrees to the original horizontal. Most tensile tests on YT seem to be on round bar, where the angle is not so obvious, but here is one plate example. You should be able to find clearer ones, or have a tester in your own college to video. m.kzfaq.infoEsRht8gF2A4

Team Mason.

I do find it very interesting, but also very disgusting, and asinine, that google covers up so many things that would be visible, otherwise !

Sheesh. It’s always Seattle’s fault!

Wrong .......south Vancouver island. Small BC story.

You're so skinny nick wha happan?
