Harold Tobin - Megathrusts and Splay Faults: Investigating Sources of the Next Cascadia Earthquake 

Drove over from the West Side for this lecture. It struck me as 300-400 level content and I only took Geo 101 some forty odd years ago (at Central), but my brain didn't hurt too much trying to keep up. Regardless, it is very invigorating being in such an outstanding learning environment.

Splay faults ! A new one for me, but every day is a school day, thank you Harold Tobin and Nick Zentner !

My wife and I live in Anchorage, and there's some pretty amazing stuff still left here from the 1964 earthquake. Along a river, there's an old road with dozens of 50s and 60s cars buried in the mud along the banks of the river

Woo, I enjoyed the excellent talk by Harold Tobin, thank you very much for hosting him, Nick, the CWU geology department!😃✨💞💗✨ Young viewers, those students sitting in the auditorium could be you, I hope you see that!!😉💫

Nick, hello from Cannon Beach. Harold's presentation was absolutely riveting. Much thanks to his graduate students for their amazing work!

Caught up on RU-vid .... been a busy few weeks around here. Loved the talk but need to watch again when I am less tired. LOTS of information flowed past and I wasn't able to catch it all on the first try. Thanks, Nick-the-Famous-in-Japan!

YT unsubscribed me 😤 I just realized it .. Can't wait to watch this video. I need to call it a day now. 📣 Goodbye, Day...

Thank you Harold Tobin and Nick Zentner, wow oh wow, a lot of this was new to me but fascinating. I am going to have to watch it again and again and try to blow up the maps a bit. What a dynamic speaker you are, thanks to a great team who obviously works well together. I hope you get the funding you need to finish this up. I hope you will come back. Thanks so much.

Watching recording from the shadow of Mt. St. Helens, Ridgefield, WA. Thank you so much for this presentation.

Outstanding work and super interesting. Thanks Prof. Tobin.

Excellent talk.

Thank you, dear nick ❤🎉🎉🎉

Always amazing stuff Nick.

A terrific presentation by Harold Tobin. Thanks Nick for posting these on RU-vid! The only critique I would lodge is when observing it on RU-vid, it would be best to have a pointer device such as the LogicTech Spotlight device for example.

I missed the live stream but i watch you on utube. Thanks for all your videos. From Maupin Oregon ❤

Great presentation style by Harold (voice, intonation, pacing) Very listenable. 🙂

That was one super lecture.

Nice to see that the Olympics are getting a new look. Fascinatingly complex area. Good talk, though way fast, hi hi.

Hey nick, have you thought about making a playlist of these Friday presentations?

Sorry to miss the live. Thanks to the professors.

❤❤❤ Thank you guys!

I would love to be a student at CWU. While there I would be so keen to be helping Nick do his research into the Spokane flood hypothesis. My goal would be to return to Australia to look for ice age remnants in the landscape here.

Great presentation and lecture!!!

I’d like to recognize the donors who helped to pay for the speakers…

Really nice talk, looking forward to hearing more about the topic.

Yes, I would have like to have seen where Dr. Tobin was pointing the stick, but viewing after the live-cast, I was able to Pause, Rewind, and Zoom into the details of the slides and mostly relate to the features that he was talking about from context. Amazing details of fine structures in the active and inactive parts for the accretionary wedge. Broad-scale illustrations of the accretionary wedge make it seem like a homogenous mass of turbidities, but the detailed structures shown by the linear scans tell a much different story, and those differences may have significant effects on the on-shore seismic damage and inundation that were seen on various parts of the coast after the Tohoku quake in 2011. It would be so great to be on the cutting edge of this kind of field research. I would be running all over the exposures yelling, “Wow! Look at this stuff! What are the rocks saying here?”

Thank you for sharing this talk!

Fascinating stuff! Thank you.

If I ever make it to Ellensburg, I may not be able to visit CWU or one of the lectures, but I'd certainly stop at Vinman's. 😀

Thank you! Grasping some weird ideas applying concepts maybe to N Madrid & ETSZ. Dont know if imagery available to get deep enuf but failed rifting we know, and sounds like at least at 1 time conditions similar. No idea how to get old enuf nor new enuf info but hmmmm.

Good presentation

We are from Gladstone, Ore. but spend with winters in Quartzsite, Az.

Thank you Nick for sharing this new-data presentation. My cut ‘n pasted question for Dr. Tobin was, “WHAT IS THE NORTHEASTERLY VECTOR MECHANISM (AS SHOWN IN YOUR DIAGRAM) OF THE WHOLE JDF PLATE, AS THE PACIFIC PLATE MOVES WNW, THE JDF TRANSFORM FAULTS PROJECT THE JDF TO THE ESE AND THE NA PLATE CONVEYS SW?”

a day late in california thankfully remembeted 5x5

Shear zone … looking at those rocks reminded me of the crazy stuff in Idaho

On the title slide... Where is that? Would love to know so I might visit in the future.

Hi all, in replay

Nick, a question please: do you know if Vic Baker's " Ice Age floods around the world" has been published. Curiously, Australia experienced ice age floods which created a string of lakes which terminated in Lake Mungo, New South Wales, the site where the remains of ancient indigenous ( aboriginal) were discovered among the lake side dunes.

Splay faults, pizza boxes.

Running late too. Finically here.

Was there any chat associated with this? How do I see it?

From here on out it's "Geology Nick" ... lol

Warden, belatedly
