Love this, Nick, thanks! The animation at the end really helped with visualizing a big Seattle subduction quake, too. Heard recently they are going to get rid of that double decker section hopefully before it gets the chance to pancake anyone ala San Francisco. See, you are being heard!
Such nicely presented information: excellent video, informative narration. My only complaint is I have watched all the available titles. Love your work! Larry
I enjoyed your lecture on the earthquake risk for the Pacific Northwest. You have an engaged and enthusiastic teaching style. The information blended well with some of your other videos about the GPS monitoring and slipping. Since I live 145 miles from New Madrid, what can you tell me about earthquake risk here? :-)
Do you mean the clockwise rotation of the PNW crust, Brad? If yes, I'm not sure that's the reason for the jog. Thanks, I've been meaning to get to the bottom of that. Many have mentioned it.
Nick discovered something just a few months ago that piqued my interest in the same phenomenon, which I didn't know even though I've lived in Vancouver for the past 34 years. The West Hills of Portland are the product of an oblique reverse/thrust fault that formed more or less by the same process that has formed many of the ridges in WA running west-to-east: The generally northward movement of the Sierra and Oregon Crustal Blocks squeezing the Washington Crustal Block between the Oregon block and the Canadian Buttress. The West Hills and the Willapa Hills along the west bank of the Columbia River form the boundary between the Oregon and Washington blocks, and the thrust and slip along the West Hills Fault formed enough of a geological channel to force the Columbia to flow northward for 40 miles before heading back out to sea. To the extent that this northward push of the two crustal blocks joins the clockwise rotation, there is at least a tangential correlation with the Columbia R. jutting north for a ways.
Thank you for the information about the large earthquake in the north of China and how the people were able to survive. China has suffered from some of the most disastrous earthquakes and seismically generated landslides in history. Even though the earthquakes subsided in that region, it is always susceptible to large earthquakes in the future.
This is exactly the sort of response I would expect from the area. Analyse and computerize the heck out of it. They may not be able to prevent damage, but they will be able to watch it happen down to the millimeter within seconds of any event.
The short answer is, yes, they do. I've seen some of the data from these GPS arrays on the uplift taking place along the coast and it's an eye-opener. It's slowly writing the story of the two plates colliding and pushing the coast inward and upward, until the next mega-quake occurs and the coast drops again and restarts the sequence.
Excellent Video Nick,this just one of the area's I have been self studying for the past 10 years or so. I knew most of this information already except for the CWU PANGA project. I would love to know if the data is available to us in real time? I sure hope so. And thank you for the outstanding video's
saturnday So much fun to learn from Nick. If you are curious and excited to learn geology, he is likely just as excited to share what he knows with you. *edit spelling*
You should probably lead with you loving the highlights of Washington. I respect your work, but find it lacking in really looking at the State. In the Willipa Hills around Boistfort Valley to Ceres Hill, there is so much geology of true interest to the state and humanity up that part of the Chehalis River valley. That's alright, we know how special this region is geologically, but hey... we can't all know what's under or feet. The farmers know, but you experts??? Want to sell guide books??? It's our taxes you benefit from as well don't you? We are used to being ignored here in Lewis County. You know more about Japan than right here. Tell us we are wrong, then show us the data...
Why in the world would someone give a thumb's down on this guy we all love and admire???
We need more professor Nick videos👍🏼👏🏼👏🏼♥️
Absolutely fascinating. The video of an evolving earthquake and its effects on the urban environment is great. Thank you, Dr. Zentner.
Thanks Brenda!

That was the Oakland Cypress section
Thank you Nick, you make geology more personable and down to earth. I live in Seattle but I want to attend your class.

Thanks much, Larry. Maybe there are new programs for you at www.nickzentner.com

I'm really out of it with New Madrid, Larry. Failed rift was the talk 25 years ago when I taught in Ohio. Wish I had good info for you...
Love the music
Do the people in this video have pagers that will beep if something big happens?
I wonder what direction does Vancouver island move? If it moves.
Very interesting video Thank you Nick 😊
You may want to update this, since the Alaskan Way viaduct in Seattle is gone now.
The twisting northeast movement that is still occurring that gave the Columbia the jog to the north is very apparent with the GPS.

我记忆起开发中国地皮之前，中国也是重重山脉森林。有一次开辟到南部区域在占地约500里的区域与农耕地工作者约50千人一起居住！有一次北部发生大地震，逃跑至南部我们这500里区域的有约一百千灾民，我们没有多出的房子及粮食供应给灾民，灾民自己想办法以树枝塔简单camp屋自己栽种一点蔬菜。北部农耕地都被摧毁了，米价格起至一斤一百万元，第三个月一斤一千万元。还好第四个米开始跌价。大地震区过后的小震也停止了，一百千灾民也急着回家乡做重建了。

Do GPS receivers measure up lift?
The short answer is, yes, they do. I've seen some of the data from these GPS arrays on the uplift taking place along the coast and it's an eye-opener. It's slowly writing the story of the two plates colliding and pushing the coast inward and upward, until the next mega-quake occurs and the coast drops again and restarts the sequence.

+Ivape Scott Thanks for watching. Yes, real time data is at PANGA's website. www.panga.org/
Thank you Nick. It will be fun to watch ans learn from it.I can't wait for another of your Lectures
A matter of when.
Yup.
WHY A DUCK IS NO MORE. NO MORE PANCAKES.
You're supposed to look at the rocks -- not eat them.

I feel like i'm the only person who still is watching these videos.
I like 'em too...
saturnday oh no you're not!
We didn't really know what we were doing back when we made these. To see an improved product, please see nickzentner.com and thanks for watching.
Thank you Nick... Nice web site. You really do care about bringing young people into the geological field.
saturnday So much fun to learn from Nick. If you are curious and excited to learn geology, he is likely just as excited to share what he knows with you.
