GEOL 101 - #18 - Styles of Volcanism

[@steverundle8635]

Viewing from North Carolina. Hello and glad to see y’all again!

[@johnholden3577]

I love the first 10 to 15 min. That part is almost as good as the lectures.

[@Poppageno]

Nick, as you might know(I know there is a lot of us to keep track of) I have been watching first your 5min geology then the lecture series, I have read terms and understood them with repeated use, BUT, I could never get the relationship with the igneous rocks until todays chart. It was/is a door opening for me on this! Thank you! I couldn't wait to share it with my neighbor!

[@XRPMcLoo]

Absolutely fantastic!!! Thanks guys, Ben stay at it, you were great!

[@cougarpebble]

Good job Ben !!

[@cougarpebble]

Great

[@oliviarafferty]

I love the "ten minutes of nothing" even though I watch the livestream later. I go make a cup of tea while I hear Nick warbling in the background -- there's something relaxing about the classroom atmosphere

[@douglaspohl1827]

BEST lecture to date; 720 video, crisp audio, well prepared syllabus with a smile! Thank you Professor!

[@kellyhorton1462]

I like the first few minutes before class starts. It's awesome. Tytytyty for all you do.

[@janehallstrom7628]

Thanks Nick--A great class for me! I also appreciate that we got to hear Ben's presentation. Fascinating.

[@stevenfullenwider3178]

I know that this is late and after the fact, but I wanted to say my piece. I enjoyed Ben's presentation. He was well spoken and understandable, important when you're trying to communicate ideas. He had flair and used humor to keep his audience engaged. It is sad to hear that so much is unavailable to him and I would assume many other students due to our current situation. To all of you, good luck and keep after it. The harder it is to get, the more you will appreciate it after you have achieved it.

[@lisac5287]

We too very much enjoyed Ben's talk. He's very engaging.

[@tomastaylor]

Ben's presentation was really interesting. He's a natural!

[@104thDIVTimberwolf]

I would bet Nick teaches his Communicating Science class. There's too much similarity in their styles to explain any other way.

[@seckens]

Thanks Ben that was awesome. Hope to see you again.

[@djiminitwo908]

Outstanding - The definition of a great teacher

[@margreetanceaux3906]

Eastbound & down - love you, Ben!

[@markfeagans9679]

I enjoy Nick and every guest of his. If I were 40 years younger, I'd be in the front row of every class of Nick's. These videos could turn an I.T. geek(like me)into a geology major.

[@rosiealaniz3205]

Im 68, English is second language and taking my second semester of College Geology. Love Prof Zetner

[@tennesseenana4838]

Ben did a very good presentation. I am impressed with him and know he'll be successful. My very best to Ben with his future plans!

[@mrtony1985]

Great job Ben! I can tell you really know your stuff. Like yourself I get nervous sometimes when I start speaking in front of people. I could tell as you kept going that you settled in and really started to get into a flow and shine. Great job! 👏

[@TheRealjteel3]

Hey Nick, staying in the shadows... you've helped me understand so much! Sent link to Iceland Silky hoping to spread your generosity, hope you get some more hits, Thanks for all you do!

[@dancooper8551]

Excellent presentation Ben! Learned a bunch of interesting new things. Good luck with your research and thesis.

[@cougarpebble]

Good work

[@jennysk2057]

Thank you Professor Z. and Ben for the great lectures. Suit up well Ben, that area is still very contaminated (radioactive).

[@joycecaudell6047]

I enjoy Ben’s sense of humor!

[@shannonreynolds4423]

Good job gentlemen. Ben you did well and kept me interested.

[@phil4341]

I've been told by an old timer that the Vantage area was a big meeting area for many tribes and seasonally was one of the biggest Native American trading areas.

[@laurienielsen8031]

Good job Ben!!!! Let us know when you start a channel.

[@cougarpebble]

Good job Ben !!!!!!!!!!!!!

[@wendygerrish4964]

I enjoyed Ben's presentation. Very nice candid engaging etc. Well done.

[@jackandlute1570]

Great presentation, Ben. A lot of clear info in a short amount of time. Classic Nick 30 minutes in, had to rewatch several times. Fun catching you do this! Your teaching style is a big part of what’s caught my interest for years. From a CWU student in ‘76 & ‘77, living in Redmond, WA. I hope you continue with 351 this Spring term.

[@lesabe6826]

Good job Ben. Kept my interest and inspired me to do my own research on such places. Thank you!

[@montanawardog]

A great two-fer on the lecture circuit, the master lecturer and his young padawan! I thoroughly enjoyed both presentations, I wanted to be in the room to sotto voce the responses, but young minds and all that. Ben, seriously a great presentation, I see some great suggestions from @tinkmarshino and mostly agree on the writing time when it comes to "canned" presentations as opposed to a live lecture. In a live lecture, the movement and actions by the speaker improve audience engagement. Probably the reason most of us find Nick so enthralling as a speaker.

[@rinistephenson5550]

Well done, Ben. You look like a natural in front of that camera!

[@maxinee1267]

Wow what a nice job Ben did with his presentation, that is quite big study goal, I hope he gets some answers. thanks so much.

[@MrFmiller]

That was an excellent presentation Ben. You’re a pretty good orator. You kept my attention to the very end.

[@rogerrodgersen7702]

Thanks for your contributions ❤️ from 🇦🇺 ⭐️⭐️⭐️⭐️⭐️

[@larrygrimaldi1400]

Ben was great, have that subject area again!

[@DarrylWilletttoy4rn85]

Very well done Ben. Showing some personality during the presentation helps keep the audience engaged.

[@margreetanceaux3906]

Love the 10 minutes; makes me feel 50 years younger (watching geology makes me feel very young anyway), with the proverbial ‘academic quarter (of an hour)’

[@luzhu7373]

Good job, Dean! Interesting, exciting project!

[@4of20]

i liked this guy, good story teller, you can tell he is a bit nervous maybe but he is great i hope he will have a channel to view his work and progress, thanks a lot Ben if you read this! from a fellow Texan ;)

[@kevsk22]

Thank you Nick and Ben, interesting lesson as always. sorry I couldn't catch it live

[@roddixon368]

Continuing in catch up. Watched your work on Saturday, but am more interested in content which continues to be excellent.

[@platformstrange1794]

Worcestershire sounds like Wooster-sheer....sauce. Leicestershire similarly lester-sheer Gloucester, Gloster I agree with you on Oceola though. Keep up the good work sir.

[@judischarns4509]

I'm watching in review. I think I'm finally understanding magmas. They are the result of melting crust, not magma coming from the mantle. Thanks.

[@mt.sylvania9218]

Watching the class on replay and Nick talking about stratovolcanos holding the gases in and don’t erupt very often. Right then I got an automated text from USGS ( which I’m signed up for) of a M4.0 quake on Mt. Hood: 1 of 10 FRM:[e-mail](USGSENS) SUBJ:2021-02-09 05:34:17 (M4.0) Washington-Or MSG:== PRELIMINARY REPORT == Event type: (Con't) 2 of 10 Earthquake Region: Washington-Oregon border region Geographic coordinates: 45.512N, (Con't) 3 of 10 121.593W Magnitude: 4.0 Depth: 5 km Universal Time (UTC): 9 Feb 2021 (Con't) 4 of 10 05:34:17 Time near the Epicenter: 8 Feb 2021 21:34:17 Local standard time in your area: 8 Feb 2021 21:34:17 Location (Con't) 5 of 10 with respect to nearby cities: 0.9 km (0.5 mi) SSE of Parkdale, Oregon 33.6 km (20.9 mi) WSW of The Dalles, Oregon 53.8 km (33.4 mi) EN More?

Near a lava flow but who knows if it is crustal or volcanic. 45.512N 121.593W

[@ruthamos2312]

Ben, all you do on a roundabout is hang right until you reach the street you want to exit on. Do not ever turn left, somebody coming the other way will cream you...probably not, most people do not speed in a roundabout but who needs the scare. Also do not try to go next to a big truck or bus even if you have apparently two lanes, the curved structure could get you scraped or worse...at least, that is what the signs in my town indicate. You need to yield to whoever is in the roundabout or who looks to enter before you can...no place for a race, the curves aren't engineered for speed. Just wait, you usually don't have to wait long although people have told me a roundabout on a main road in front of a little sort of enclosed community is almost impossible to enter during rush hour. I've only been in that neighborhood at other times and had no problem although the main road is pretty busy which can disadvantage the secondary road's drivers. People will treat a roundabout like a four way stop and offer a right of way to the driver to the left of them even when the right of way is actually theirs. this happens usually when the roundabout is new to the community. I usually wave the other driver on, do not want to enter the roundabout and get clobbered by the other guy realizing he had the right of way after all! If the other driver still insists I go first, I yell a thank you and trust him at his word. The roundabouts in my town have facilitated traffic flow for the most part, they are easy to get used to.

[@jillpruett4772]

Ben needs to do a side gig as a comic! Good Job.

[@TimInSeattle]

Great job Ben.

[@ericsarnoski6278]

A bit late, but thank you Ben for your presentation on Geoarcheology along the Columbia river. I'd like to see you do a presentation on carbon dating the layers where archeological evidence is found which might give us an idea if indigenous people might have witnessed some of the later glacial floods.

[@jeniferhoffman15]

Could the Siberian Traps have been an "un-detonated" caldera?

[@johngautreaux4296]

Thanks Ben, keep up the good work,

[@daysiewaysie]

i'd like to know why it isn't possible to effect a controlled release of pressure from the magma chamber beneath a supervolcano. Given the enormity of an eruption and the existential threat posed to all of mankind, have the brightest scientific minds not yet even come up with any possible options ? Or, is the magma chamber just too deep into the crust to be reachable ?

[@richardstephens3642]

I really enjoy the subjects, but i also enjoy the banter with you, the students, n the other follower's 😂😂

[@KarenUntz]

I thought the presentation was well done. Kudos. Thanks for the class! I'll go back to the beginning and catch up! 😎

[@gaylescovel7308]

U were recommended! So here i am.

[@gaylescovel7308]

Interesting for sure. I listened to it all while embroidering. Enjoyed volcanos more than embroider!

[@greggarw]

Nicky done Ben you may wish to have a watch of a archeology program we had over here called time team. That use a lot of geophysics to try to find archeology under ground using various methods from radar to magnatizam you may well find there methods of interest to your project. Over in the UK sorry should have added that needs the top.👍

[@KarenUntz]

Love watching Time Team!

[@dennydargan8731]

Ben kept me awake. A plus.

[@davied5496]

Thanks Ben , enjoyed

[@tinkmarshino]

Not bad Ben.. to much time writing. Maybe have the names of the places already written that will give you more time to tell us what you do, and what you have found, and what you expect to find.. Great base to work from.. One other suggestion maybe have marked on the map the reactor b site and some of the old sites so that folks that are not from here will know that is was just that little pocket south of the river that held the plants.. Now my question the white cliffs you spoke of leave the confines of the river just before the "horn" is that because the river used to flow there? Or was it caused by flooding? I did find your talk interesting.. thanks Nick! and thank you BEN..

[@sethhuyett6539]

I agree. You tell a great story, and the writing tends to interrupt the flow.

[@tomunist1]

Best prof ever.

[@jessetrott2549]

thank you

[@dharma11]

Did Ben by any chance do any graduate work at the University of Texas at Arlington? I think I took some classes with him

[@randyferron]

Does Ben have a muscle car , I noticed his Holley tee shirt?

[@dannymccarty6680]

24:45 Write this down. It will clear up dark clouds of confusion before they occur in your mind’s future. REAL DEAL!

[@wiregold8930]

Really well done Ben! Clear voice and good cadence. I appreciate your reading out terrace levels Holocene H1, H2, etc as I'm in a poor signal zone and my replay quality is 240 so I cannot read clearly. Perhaps a flexible, thin whiteboard w/ high-contrast markers instead of paper or maybe just a larger diameter marker? Marker squeak was a slight distraction but that's probably more my hearing.

[@conniead5206]

I do not know if Geologists and Volcanologists knew about super volcanoes before it was realized that the ground was lifting under a lake in Yellowstone. It was when the rest of us found out about them. Over the last few years the news media has decided to label some cone volcanoes as super volcanoes. Probably because of where they are located. One is located on the mainland of Italy and is next to a large city. I think it is Mount Aetna.

[@richardstephens3642]

Composite cone: cross section layers, like rings in a tree?

[@warg2122]

im here to upvote Ben

[@alicestevenson4591]

What about campi flegrei in Italy?

[@otterssilver7299]

WHAT ABOUT THE GRANITE OF COLORADO FRONT RIDGE. WASN'T THERE A SUPER CAULDERA AT ONE TIME THERE?

[@hobsondrake]

if it is at all possible, lower the camera to the eye level of the presenter.

[@johnnash5118]

Oregon's Newberry Shield Volcano/Caldera, el. 7,989 feet (Paulina Peak @Rim) is 37 miles East of the Cascade crest, but its origin evidently is still a product of Cascadia Subduction, not the long-held belief of a hot spot. At 1,200 square miles and with a volume over 140 cubic miles, it and its twin are the largest volcanoes in the Cascade Range. Due to its location between the Cascade volcanic arc and the NW corner of the Basin and Range; magma plumes, and a thin lithosphere from plate extension (@22 miles thick) are its volcanic mechanisms. Newberry has more than 400 vents, the most of any volcano in the contiguous United States. Unlike other shield volcanoes, which erupt basaltic lavas only; Newberry Volcano has also erupted andesitic and rhyolitic lavas. goo.gl/maps/22gFVfCkJJcMjPtb8 Newberry has a twin @280 miles due South on the same meridian line; Medicine Lake Shield Volcano/Caldera, el. 7,921 feet is 35 miles East of the Cascade crest, but its origin is evidently still a product of Cascadia Subduction. At 1,200 square miles and with a volume over 140 cubic miles, it and its twin are the largest volcanoes in the Cascade Range. Due to its location between the Cascade volcanic arc and the Basin and Range; magma plumes, primarily basalt and basaltic andesite, and a thin lithosphere from plate extension (@22 miles thick) are its volcanic mechanisms. It's massive volume causes a 1,500 foot downwarp of the underlying bedrock. goo.gl/maps/8eA3aYqQZ1Dejp8x6

[@nessthemess482]

Approx 13:00 , Tim must have been late to class lol, the disappointed look on the teachers face.

[@djfauna66]

Id pay good money to see a mount hood video!! Ik oregon is not nicks specialty but its close enough haha

[@skalmelid]

Thanks and well done Ben. Did you notice btw that your writing got smaller and smaller? It tends to do that when writing on a board unless you pay attention. Been there, done that ;-)

[@bobchiles74]

From Diesel Mechanic to Geo-Archeology - not sure which one is harder...

[@susanliebermann5721]

Ben, thanks for your contributions! Sorry I had to watch in replay. Question: How in the world did choose this specific field of study? What led you to study fluvial geomorphology? How do you see your work fitting in to the bigger picture of the geologic history of this region?

[@rozswartzett180]

🙏

[@Aschmorr]

Haha Ben is definitely from the south, I just can’t pinpoint where, I’m gonna say South Carolina or Alabama

[@Aschmorr]

Lol Texas!! He said it 20 seconds after I posted that!

[@Aschmorr]

I miss Texas, and Ben, technically there are mountains in Texas, in El Paso, they’re called the Franklin mountains

[@lauram9478]

❤

[@tomhall7633]

I still have outlaws that talk just like that. Pass the PEE-caun pie if ya please.

[@SuperLAndrus]

Why do you NOT just flip the chalk board over instead of rotating the entire thing? They are built to do that.

[@MegaStairman]

Nick..I was a college student when you were a kid...one thing that drove me nuts because I was a bit introverted was a professor of oceanography that taught like you did today..dragging bad mediocre or good guesses from students drove me to hate the subject even though I loved the ocean and spent a good part of my college years working on the ocean to pay for it...do n t sacrifice some good students because of that technique...one guess two..ok but not ten minutes

[@Ellensburg44]

Hate the subject due to an inclusive instructor?

[@MegaStairman]

@@Ellensburg44 not forever just walking into that class. The technique is ok to a point but that guy dragged it out like a deer harvested way too far from the truck.

[@Champstarrable]

There are mountains in western Texas sir.

[@dpcnreactions7062]

Hummmmma, I thought Tephra came out of the shield Volcanoes. There is a KZbinr in Hawaii who talks about it whenever he walks around Fissure 8! Ok, Fissure 8 was very explosive!

[@snarky_user]

Well, if you're going to blow your top, you might as well be stylish about it.

[@davied5496]

You want to kill the mic when you're talking to the students offline

[@Ellensburg44]

No I don't.

[@KathyWilliamsDevries]

No way! That’s the fun part! Wish I’d had professors who took such a personal interest in me like Nick does with his students
