35:00 live in Scotland and we do okay in our little thatch roofed huts. LOL I know what you mean though, like an old cottage built in the 1600s not built to any modern building code. Loving this series, so much info. I'll watch them all then return to the beginning to try and take it all in.
We were there for Loma Prieta. We've seen lava hit the ocean in HI. I've noticed the large crystals in granite in the Big Horn Mountains in WY. We looked at rock forms in the Black Hills with a road side geology book. You have provided so much more to my understanding. Thank you.
23:00 For me the most intuitive example of refraction is when a lawn mower is on a sidewalk the wheels on one side start to touch the grass and the lawn mower starts getting pulled more towards the grass. Sound waves travel with higher speeds the more dense the medium.
Thank you so much for making these lectures available. Geology books have always been a bit impenetrable to me, but not anymore thanks to this channel. Thank you especially for sharing them for free.
Started watching the lectures for a second time and realised that you teach in a very systematic, clever and accumulative way. Like dropping stones into a bucket, in my case. Sincere thanks.
Thank you so so much for creating these videos! I am a freshman at LSU and your videos helped me learn and study for my exams and are also the reason I am going to end the semester with an A in the class. Thank you so much!
That's wonderful! I am so glad you found these lectures helpful. I know some of the geology faculty at LSU (great school!) and my heart is always in Louisiana (I'm a Cajun but was raised in California).
Professor Day, you're absolutely a marvelous teacher and know so much...just a quick clarification at the 27:45 timestamp, Pakistan and Afghanistan are west of Nagpur, at the 8200 km reference data point on the map :) But you're 100% correct, the Eurasian and Indian plates are located right there and these two developing/undeveloped countries will certainly bear the biggest blows of earthquakes, also Iran and Turkey, as well
This is the first earth quake video I watched as I was more interested in volcanoes. This video just brought back my college (Mohawk College) term at McMaster University Science & Engineering Electrical Services.(Both in Hamilton Ont Canada) I have memory problems and have not thought of college for, I honestly can't remember LOL , long time. My long term memories are intact but my short term memory is terrible. Any ways I am rambling. I helped build a sensor for earthquakes at McMaster, and this video has just made me happier that I have been in a long time. I keep re-reading this. Yes emotions are in my long term memory. So Thank You Ever So Much Michael Garrison Ancient and wore out like a model A Ford. Slow, backfiring, hard to start and need a lot of maintenance.
How freaky, just watched this not long ago and an earthquake happens of the west coast. Thank you for the knowledge presented in this video. Now listing to news and reports, you can pick up and understand a lot more. :) Perspective just enhances. Love it. Thanks
Thank you for making these. I have become obsessed with geology after my car broke down at a rural road cut and I didn't have anything to do but look at the rocks..
46:10 I hope the pooch is ok. I commented on the last video that he was a bit annoying. Even though I'm watching 5 years later I would certainly feel guilty if the time space continuum somehow connected me with this valiant beast and led to his discomfort.
You probably know the answer by now, but however.... the answer is yes, although the one shown here is just a schematic. A full-three-axis system has two of them orientated N-S and E-W, the third being up-down. This gives all the information necessary. A simpler single-component seismograph might be used for a school or an additional source of data.
Lethargo G Peterson S-wave motion is fairly complex when you get into the details of it, and in my lecture I kept it very simple. In general, as S-waves move away from the source they can be thought of as planar, 2-D waves but near the source there are perpendicular and parallel components that give it a 3-D wave structure for which the math can get nasty.
It's being redone and should be published within the next few months. It's a lecture that will focus solely on the Earth's interior. Hopefully you'll be back to check it out!
Ahaha “Giving Earth a sonogram”. You know, before it gives birth to psycho monkiies that... nvm. Have kids and come back to this then... you’ll get it! So a thrust fault is about like the events within a deep ocean trench? Update: “Ripping paper? Yo, just teach what friction is.Much more efficient description to describe an earthquake.

We call that inertia or conservation of momentum. Oh man I need to sleep now. Thanks professor! Very much!
I love watching people explaining what they've been taught. I have an inkling that tectonics is not real. Alfred Wegener didn't say pangaea inched apart, Alfred said Pangaea was violently shoved across the sea floor and forced the sea beds off the Earth shell. read Jajoka's Theory

Thankful for these videos as I study for the FG and for the bird sounds in the background
You are very welcome!

That’s an interesting comparison. I may use that in my face to face lectures.
Thank you so much for making these lectures available. Geology books have always been a bit impenetrable to me, but not anymore thanks to this channel. Thank you especially for sharing them for free.
I go to the University of Alaska Fairbanks, and I really enjoy your videos. They are straight to the point! Thank you so much for you videos!
I appreciate that feedback!
9:52 its like art and science working together, that's really cool

Love it. Thanks
Thank you!
Great videos :) Will be watching more before my final
Thank you so much!
Great content! You explain very thoroughly and clearly.
Great graphics for wave types.
Metrically-challenged! Loved that one.
Thank you! This was really helpful to study for my test..
Thank you every much! You are a great teacher!
Very knowledgeable.
Nagpur is more to the west in India than shown on the map.
Thanks for the correction!
Been in a 6.2 with months if aftershocks reaching to the 5s and 4s. Never got used to it.
Thank you for making these. I have become obsessed with geology after my car broke down at a rural road cut and I didn't have anything to do but look at the rocks..
That is awesome!
thanks! as always super well explained!
Thank you so much . This lecture was really very helpful.
Glad it was helpful!

Very enjoyable, once again
What is lecture 13 and 14 and 15 about? And are they available somewhere?
They are being re-recorded and updated.
46:10 I hope the pooch is ok. I commented on the last video that he was a bit annoying. Even though I'm watching 5 years later I would certainly feel guilty if the time space continuum somehow connected me with this valiant beast and led to his discomfort.
Does a seismograph have to be oriented in a specific direction to work correctly?
You probably know the answer by now, but however.... the answer is yes, although the one shown here is just a schematic. A full-three-axis system has two of them orientated N-S and E-W, the third being up-down. This gives all the information necessary. A simpler single-component seismograph might be used for a school or an additional source of data.
I love your lessons! Thanks for sharing them.
BTW... I guess "meteorites" would be a great video-lesson!
I have it on my list!
Great lecture, but the method of finding the epicentre is TRILATERATION, not triangulation. Thumbs up for the content! Thank you :)(:
You are absolutely right. The correct term is trilateration. Thanks for the correction!
Really helpful
I am Metrically challenged. So, can you give me the the conversion factor to convert Millipedes to Centipedes.
Now I have to Google this "Wiley Coyote" character.
😯🙏😍👍👍👍
Nice intro to earthquakes.
So if S waves displace rock perpendicular to the direction of travel, that could mean left-to-right AND/OR up-and-down, is that correct?
Lethargo G Peterson S-wave motion is fairly complex when you get into the details of it, and in my lecture I kept it very simple. In general, as S-waves move away from the source they can be thought of as planar, 2-D waves but near the source there are perpendicular and parallel components that give it a 3-D wave structure for which the math can get nasty.
Thank you!

Amen 🙏
You pointed (27:45) Pakistan and Afghanistan wrong ;p
Sometimes I make mistakes. I try not to make too many though.

Thx for the imformation XD

excellent lectures , thank you ,pls ist possible to get PPts for these lectures to help us then help our students .thx in advance
