Volcanoes: Formation, Types, and Activity 

This video seems pretty fitting to what is going on in Iceland right now. Thanks!

Always a good day when Dave uploads. Volcanos are an enjoyable subject for me, thank you so much!

The Colombia river basalt flats are fascinating. The terrain changes so drastically when you travel thru central Washington and Oregon

Alevel geography student from UK here, really helpful & informative video thanks!

I learned about volcanoes and earthquakes when I was a freshman year in high school. And, I took an earth science class at that time, and I still remember them to this day.

Another informative, well presented and detailed video. Thanks Dave!

Love this video format. MOAR (please)

Thanks again, Dave.

Thank you for detailed information of volcanoes.

Please continue the geology series

Professor dave is amazing ❤❤

Hey Dave if you do more volcano stuff, I have some really fantastic eruption video from when I was in Guatemala! Including some drone video

When are going to get video on Matt Powell??? Anyway, amazing work as usual

Wonderful 😊

🌋 Visited Snake River, ID this year and got to see some old yellowstone igneous formations

Hey Dave, I don't know if you take any suggestions, but if you do, since we're on the topics of volcanoes and you like to debunk some pseudoscience-related topics, I think some kind of look at the hysteria surrounding the Yellowstone "supervolcano" would be an interesting one. I have a lot of personal experience with this one as I had a severe bout of anxiety when I was younger, being very interested in science and learning about things like Yellowstone and black holes and gamma rays and such scary-seeming things - and I think that I kinda stopped being as interested in learning about these kinds of things for a fair while because it was just so anxiety-inducing, and I'm looking back on that regrettably now that I've been interested again. I know that living with that kind of fear can be crippling and bad for your sanity. I think that having something to be able to debunk / address a lot of the things that cause hysteria and public panic, be they specific claims by some clickbait video or just the general public notion that Yellowstone is "overdue to blow." It also really frustrates me because I absolutely love the geology of Yellowstone but it's next to impossible to get any actually good resources on it without also being bombarded by fearmongering about it. If my experience is anything to go on, this kind of panic without knowing much about it can be quite harmful and damaging to both public discourse about both the geologic wonder of Yellowstone as well as volcanoes in general, and mental health. If you take it up, maybe you could also cover some of the ways in which scientists study and keep such a close watch on Yellowstone, which would both be enlightening for how to specifically deal with claims about Yellowstone, as well as about how real scientific observation is done as we speak. I know for one thing it's really grounding to know about how science is done, what it can do and its limitations, and it helps to break the perception of Science as being some kind of magic, and learning how these things work can help to understand how scientists think and find things out, rather than relying on notions of 'green chemical go pour in red chemical in beaker = science' or, god forbid, falling into the "Science is DOGMA" narrative. And it would seem that it's a lot easier to dismiss pseudoscience and lies about science when you have some examples like that.

Thank u Dave Can u please different types of volcanoes in Cascadia region which included Mt.Hood and Mt. Rainier???

Very cool

Is no one going to talk about how cute the little cinder cones are? They are like a toy volcano except good n fiery!

Wow so good explan

I wonder what the flat earther explanation for volcanoes is…

Hello Dave, I have recently passed the last stage of treatment for a Lymphoma (NHL,) which consists on an autologous transplant of hematopoietic progenitors. Would love to see you going over how this treatment works. Cheers

What happened to the applied chemistry sessions?

Good very good ❤

14:09 is that La Soufriere eruption in St. Vincent that happened in 2021?

Pretty apropos for what's happening in Iceland right now.

Way to go Dave - another very educational & informative piece - even for us “older” folks!

Its happening now in Iceland. Which is in the mid Alantic ridge.

Person driving the truck at 7:42 is probably swearing profusely with the gas pedal glued to the floor.

Professor Dave puts out a video on volcanoes and 19 hours later Mount Etna erupts. Coincidence? I think not.

I hate to contradict, but the statement "volcanoes are present on every continent" is technically correct as there are remanets of extinct volcanoes in Australia, but there are NO ACTIVE volcanoes on the Australian mainland, particularly where the “global map of volcanoes” show one somewhere between Adelaide and Melbourne. Having traveled fairly extensively through that region I can categorically state that “there is no active volcano there”. If fact the area is known for its extensive limestone cave networks that have been formed over millennia by water dissolving the limestone and forming numerous spectacular formations, but definitely NO ACTIVE VOLCANO.

This kinda makes me wonder-- Why was the Hunga Tonga 2022 eruption so explosively powerful?

Sir what is the potential energy at the centre of the Earth?

Yellowstone: hold my beer

Living around volcano's is crazy, but that soil though.

Hello Dave - I’ve been trying to sort out the whole Palestine-Israel conflict. Can you make a video on it?

Any flerfs tried to tackle plate tectonics?

Hello

This certanily is a "hot" topic!

VOLCANOES!!! (just one question: Is Yellowstone going off like a Tsar Bomba nuke in the movie "2012" LEGITLY possible?)

suspicious observer's favorite video

I love you science jesus❤

That STRANGE continent again? Annarticka?

Professor Dave is time to engage the flat earth community lol

AHAHAHAHAHAHAH Blocked

Thanks @ProfessorDave. The sciences of Plate Tectonics & Vulcanology are both awe-inspiring, mesmerising & terrifying. ~ ⦿ ~ That people casually live close to active Volcanos blows my mind. I get that they're mostly like Mauna Loa, making them pretty unlikely to suddenly detonate like a nuclear bomb, but - with problems like toxic gas, rivers of boiling water/mud & the ever present sharp-edged volcanic ash particles shredding your lungs - it still seems extraordinarily dangerous...
