Geologic History of the Jemez Volcanic Field

[@harrietharlow9929]

Very interesting. Volcanism in this area is an interest of mine so I was glad to find a video on it. Thank you for posting!

[@matruthn.m.bassin]

I love my state and our earth very good stuff here 🤙🏽

[@chrisanthony7481]

very well done video.... incredible graphics! Thank you for this!

[@michaeldeierhoi4096]

I have visited the Valle Grande and surrounding area many times as I have lived in NM for 30 years and yet this is the first time I have seen this video. The volume of ejecta is always impressive to hear about as well as the familiar explanation of the intersection of the Rio Grande Rift and the Jemez lineament. This video had decent enough graphics to make it clear.

[@phoenixlyon7454]

Nicely done! Wish it were longer though.

[@Nmepscor]

It's actually part of a larger film that premiered on PBS called Valles Caldera: The Science.

[@greenman6141]

This was excellent and fascinating. So enjoyable and educating.

[@aoconnor2933]

I love this and visiting the Jemez Culdera!

[@2hacksbuilding82]

It's amazing to be there, in the heart of an active supervolcano

[@zr2jake]

This is a great explanation! Thank you!

[@tommunyon2874]

My friends and I would start out from Los Alamos in a generally northerly direction to see how many consecutive ridges we could cross. We usually needed to start home after starting up the third ridge. The dream was to make it to Abiquiu, but a brown bag lunch was never quite enough provisions for the trek.

Narrator: I could easily understand every word you said. Thank you :-)

[@georgesheffield1580]

Bad spanish diction exception

[@dorianmclean6755]

Be sure and take a soak when visiting the wonderful hot springs ;-)

[@michaelmattson1081]

thank you for correct local pronuncation❤

[@AlexRomero-f1s]

I live in taos. We have 40+ volcanic vents just in the county alone

[@MartinMMeiss-mj6li]

At about time 2:40 it is stated that the ash from the eruption rose twenty miles into the atmosphere. How can this be known? From how far the ash spread? Wouldn't that depend on the strength of the winds that prevailed at the time as much as it would on the height of the as plume?

[@hamaljay]

Science.

[@MartinMMeiss-mj6li]

@@hamaljay Science? Care to elaborate?

[@michaeldeierhoi4096]

​@@MartinMMeiss-mj6li The Valles Grande eruptions have been thoroughly studied by geologists for many years. And based on the known amount of ejecta, the wide area that it was deposited over and comparing that to other more recent eruptions the height of the eruption column can be estimated. This was a super volcano so its eruption would have been far more devastating than anything in modern times including Tanbora in 1815.

[@dragonridley]

​@@MartinMMeiss-mj6liIt's based on how far out rock fragments of different sizes are thrown.

[@dragonridley]

​@@MartinMMeiss-mj6liAlso, they can tell the wind direction at the time of the eruption based on how it's distributed then they measure the spread perpendicular to the inferred wind direction.

Love caldera!!!

[@edmolash3401]

Why does the Jemez Lineament exist at these locations? No answers here.

[@michaeldeierhoi4096]

The Jemez lineament is thought to be a weak point in the Earth's crust and at some point in the distant past may have been a suture line between 2 continental masses. As you may know from plate tectonics the continents have moved around for billions of years. Who can say how old that suture line is but it could be at least 300-400 million years ago when the continents had rejoined before breaking up again.

[@prabhakarv4193]

Very nice

[@stanleyhenry2687]

But the Emory Caldera is a bigger then Valles Caldera

[@michaeldeierhoi4096]

But, but, but, there is always a bigger one somewhere. Yellowstone is probably the largest caldera in the US and Toba in the Sumatran peninsula is bigger still!!

3:30 America, we literally use any measurement but the metric system lol

[@rhetta9826]

Can you please stick with metric ? Cubic kilometers not cubic miles. Thanks.

[@kathygriffin9465]

Give both miles and metric measurements, then likely no whiners

Thanks ,I commented on the same

[@johnemerson7976]

commentator should learn to pronounce Valles

how do you think it is pronounced?

Not near as bad as hearing Haymez, cannot finish video due to this mispronounciation. It's Jemez, J's are H's but e's are not a's.

[@wayawolf1967]

Does anyone even believe the "millions of years" theories anymore ? Why not a bajillion years ago ?? Millions of years is code for we dont know but you must bow to the religion of "science". Not buying it !

[@thomaswilliams373]

Grow up

[@bobertjones2300]

Gee, these numbers are based on science, not faith. Science is subject to update with new insights. Religion quickly becomes morbidly, rigidly fossilized.

[@michaeldeierhoi4096]

wayawolf just made his ignorance of science loud and clear!! Instead of ASSUMING that such numbers are not to be believed why not ask WHERE those million year estimates come from?!?! 🤔
