The Mid-Tertiary Ignimbrite Flare-up is responsible for a large majority of SW Colorado's ore deposits. Including lots of gold, silver, and copper. If you look from satellite, you can still see the La Garita Caldera via the circular depression in the ground around Creede, CO. It would have been a "fun" type to be a volcanologist back then, 25+ million years ago when CA, NM, UT, AZ, and NV had an absurd number of volcanic activity, far surpassing levels witnessed in modern day Indonesia. Another fun remnant supervolcano you can look in (not the Wheeler Geologic Area, although it is also fun) is the Chiricahua National Monument. It has 900 ft thick ignimbrite pillars which tower several hundred feet above the landscape and are still exposed. It is a national monument which honestly deserves and might soon get National Park status. Also did I mention that it also has a population of ocelots? You read that correctly, and it is in Arizona.

The way the area around Mount Saint Helens came back after the eruption was mine boggling. That being said, I remember my sixth grade teacher talking about still getting ash out of his gutter a decade after the eruption.

I was always curious about this largest of super-eruptions. It’s amazing how even the most devastatingly energetic disasters are still just part of the circle of life.

A lot of ash also just falls from the sky and builds up like nasty, scratchy snow. It’s not as sticky as snow, though, so it can blow off of things like leaves, allowing trees to still see the light as long as they’re not completely buried.

Funny, I did a presentation on this for my geology course last semester in college, and nobody else had heard of it prior to my presentation. I would have loved to see a mention of slab rollback and how it significantly lowered the pressure on the underlying mantle to cause decompression melting, though I guess that's just the GeologyHub fan in me showing.

This was a great video for me. I'm camped at the eastern edge of these ignimbrite deposits. Most of the hills around me are (if I'm reading the geologic maps correctly) part of the Carpenter Ridge Tuff, but there are some exposures of the Fish Canyon Tuff here too. In fact, I have a chunk of the Fish Canyon Tuff sitting by my keyboard right now. Not the prettiest rock I've ever seen, but it's real interesting to hold part of a 28 million year old pyroclastic flow. I'm a sub-academic geology fan, so I've been trying to understand the landscape here, and this video filled in some of the gaps, like how the Farallon Plate's behavior led to this period of volcanism. Good job, PBS Eons!

My ideas is just for surviving the initial eruption and immediate aftermath, after which I'd try to evacuate to the nearest town or city that's still functioning. A supervolcano would be pretty devastating, but based on what Eons has said, it alone wouldn't be able to destroy the ENTIRE country. (Would definitely cause huge disruptions and possibly send the economy into freefall though, depending on the scale of the destruction and what regions the volcano and ashfall affected.)

Fabulous episode. We've been studying this exact subject in my geology class.

It’s one of the things we like to point out at Mt St Helens. The time of year helped the animals. There was lots of snowpack and ice still, so many animals were underground, and protected by a deep layer of snow. It didn’t save them all, but definitely helped. Also, the animals that did survive helped the plant life recover. Pocket gophers helped bring good soil to the surface, and big game like elk left hoof prints that made areas for seeds being blown by the wind to collect in and take root. The ecosystem around the mountain is thriving, for as much as it’s associated with devastation.

So my question after seeing this video is: What is the difference between these eruptions and the ones that have caused volcanic winters and/or extinction events? If at least 25 of the eruptions of the Mid-Tertiary Ignimbrite Flare-up were supervolcanic, and the eruption detailed in the beginning of the video was so much more massive than the Yellowstone eruptions, what causes some eruptions to be so much more catastrophic? Like it's mentioned several times in the video that these eruptions don't produce much lava but primarily produce ash - but as far as I've understood, it's ash that causes volcanic winters by blocking out sunlight and forming excessive rain. Mount Tambora's eruption in 1815 isn't even classified as a supervolcano eruption but it caused several years of cooling and a lot of grief. The Late Antique Little Ice Age lasted four years and caused crop failures and famines as well as exacerbating the Justinian Plague. So did the ash from the ignimbrite eruptions just not get high enough into the atmosphere? Is it a composition thing, where the ash only goes high enough in the atmosphere when it's made up of specific elements? Is the difference between this and the extinction events caused by volcanic activity just a matter of scale, with more volcanoes going off at the same time?

@Lolibeth

Жыл бұрын

Volcanic winters aren't as devastating as people make them out. They're not on the same scale as say, the sun blocking after the KP impact. The LALIA caused crop failures, but everyone in the affected area didn't die. A lot of grief because each life is mourned, but a comparatively low percentage of people died. The population bounced back fairly quickly. And that's populations who are sedentary and dependent on agriculture. Those volcanic winters are barely blips. And what makes a lasting volcanic winter isn't the ash, it's the sulfur ejected into the atmosphere which forms aerosols of sulfuric acid. It's those aerosols that reflect sunlight and cool the temperatures, not the ash. The ash comes back down pretty quickly.
