I really enjoyed learning about the Salton Sea. My grandmother used to live in Niland at a mobile home park and spa. Driving through the Anza Borrego park was fascinating and to see the Salton Sea was so intriguing. With your explanation I now understand how all of this came to be. Lately our earthquakes have been coming from that area. I live in Escondido, California. I love the landscape of the desert and learning about it.

Dr. Shawn , first of all thank you very much for your contribution for the popularization of the geology. Pleade could you do a field series for the Engineering geology such as , slope stabilty, face mapping, rmr, q system and GSI calculations usage the brunton compass and so on Best Regards

AI voice: yes he does sound like AI but his cadence is not AI if that makes sense. The way he mispronounces my country's volcanoes was enough to convince me as AI/TTS voices would default to the nearest sounding English syllable that is more obnoxious to hear.

Thank Shawn. Got some rain I the sf bay area. Merrymerry and Happyhappy. See you next year. 👋👱‍♀️❣

We’re expecting 40c for Christmas, today it’s cool only 24c 😊. What a wild ride the last 12 months has been! Can’t wait for what’s next with Team Willsey 😊. Oops ps! Merry Christmas to you & your family 🎄🎄

Im in carson city. It wobbled the building pretty good

A very well steered interview. Good work Shawn. Sorry I had stopped watching Tim. The monotone delivery was what did it for me, can see why now and happy to give it another go.

Thanks for the update!

Just finished the paper you mentioned on the Quaternary faulting in the Walker Lane alignment. It will be interesting to see how the field work from this quake supplements the findings of the GSA paper. Thanks for the mention of that paper.

Thank you for this! Very interesting 😊

For those of us who grew up in the early 1950s and remember “drop drills,” E was the immediate choice. Our teacher, with no warning, would yell “Drop!” and that we did, under our desks, curled up in a ball, facing away from windows, hands clasped behind our necks. For those who wonder why we did that, it wasn’t about earthquakes, it was about the fact that by then, the Soviet Union had nuclear weapons. And we had plenty of earthquakes in California’s San Fernando Valley, so sometimes we had that to contend with. Oh, and of course some guy always got one hand to his mouth to make fart noises and set everyone giggling.😂

❤❤

Appreciate that too. I took an online course but yours is Way better Shawn

She is the Bomb!

?Maybe some day you could do something about New Madrid? I am right on the eastern edge

Thanks!

Hi Shawn and Mods and crew

Hi from Waverly TN

Anyone: How do you explai- Geologist: Millions of years. Anyone: But I didn't even finish my ques- Geologist: Billions of years!

The Unitias the northern boundary of the Colorado Plateau. This has something to do with the orientation of the mt range.

Hi, I have different types of rocks, interested individuals can contact me

Does that boulder that rolled in the earthquake offer a study opportunity for some enterprising geologist or archeologist? I believe there is a method of dating erosional events that try to detriment when a rock was last exposed to the sun. One side if this boulder has been sitting out in the sun for quite a few years but the other side was just exposed, so comparing the long exposed sites on the surface of the rock to other, newly locations on the rock could provide insight into how surface material changes with time.

Very helpful follow up, thanks for doing this Shawn! Sand boils? Wow, amazing. Had never heard of those before, I think... Always new things to learn! Greatly appreciated :)

If it goes the way I'm thinking, we should have another eruption about early February. I think it's going to keep popping off at the same inflation point with less of a drop during eruptions until a steady state is achieved. Kind of like the long running Pu'u O'o eruption. It's like it's pathway is still under construction and it's still prone to blockages, unlike Kilauea, that has the well established East Rift and doesn't inflate as much before a long running eruption.

Love Shawn on the Rocks!

Sorry. Out of context question for you to consider for future content. What is the mechanism that sustains the continuing Fuego volcano eruptions in Guatemala?

I live in northern California right almost exactly whare the 7.0 was and it was really shaking things for a pretty long time but the 6.4 we got a year or two ago was more like a jolt than a shake and it was much more destructive. The damage between the two was uncomparable. The 6.4 shut off the electricity and broke things, this city of like 100,000 people was absolutely shut down for days. Nothing even broke or fell when the 7.0 hit.

Many many thanks from Anchorage Alaska. Looking forward for an update concerning Mt. Spurr but I know you are a super busy talented person. I will continue to donate when I can. Thanks again 👍👍

Thanks!

Shawn, I've tried a few times to find out what the depth level is below. I suspect it is Sea Level but I have been unable to find out. Can you? I even emailed USGS and the person who replied didn't know. The reason I want to know is a quake like this one is a lot further from the surface(1,700m) if the 9.7km depth is from sea level, almost 2 more KM from the surface.

😩

Thank you, Prof. Willsey. I find it very interesting that 15% to 25% of the Pacific/North American Plate motion is attributed to Walker Lane.

SAND BOIL… word of the month 😅

What? no photo of a lawn chair that has tipped over on lawn as a result of the Earthquake? Must not have been a big earthquake 🙂 When looking at a crack or rock slide, is there a geologist way to "carbon date" the event, or is it more of a visual judgement to see if "recent" or "not revent" based on colour, vegetation and wether the crack is still sharp" or has been weathered ?

Thank you Shawn. Your analysis is always interesting and appreciated.

Good stuff Doc. That recent activity in the New Madrid region has me a little concerned.

Thanks!

This guy explains things well, and his public speaking is engaging. Sorry, Idaho, but he needs to have a wider audience.

Thank you for the update! Enjoy the holidays with family and friends.

great update as always, prof. Are quakes in this region connected to the rotation of the basin and range region? Have a good Christmas

Shawn, I hope you and your family have a wonderful Christmas and please take time for some rest and relaxation, you deserve it!

Looks like a nice cone right next to the site.

Thank you for this wonderful interview of Tim. As the mother and grandmother of several Aspies, I knew why his voice sounded as it does when he read his script. No problem for me. You do a great job, Tim! I really enjoyed hearing about your life and profession. Science rocks!!😉

Thanks!

would you have an idea how far the rock moved at the point of rupture underground?incredible power we felt it here in auburn ca.thanks for the update

TY for the update

Hi Shawn … thanks for the follow-up! I’ve noticed some folks look suspiciously on downgrading magnitudes. I’ve tried to explain why this happens, but it can be complicated (plus I’m just one voice among the many). I think it would be great if this could be addressed and further explained to more folks - more than just a few folks believe the USGS is just randomly downgrading. This one misunderstanding seems to lead to a general distrust toward earthquake science. Thanks again!

Thank you Shawn. I really appreciate the detailed update with all the pictures. I had never heard of a "sand boil" before but I feel like I know all about them after your wonderful explanation. Brilliant. Love it.

Thanks for all the hard work on these videos!
