like two or three movies in a row my mom and sister and I it's like the man with the one red shoe and Joe Versus the Volcano and Cojo um so I just I fell in love with films so I I've always been like a filmand uh so I knew who Steven Soderberg was when I was 14 I had seen sex lives and videotaped don't tell my
Even if a supereruption were going to happen at Yellowstone, we'd have some notice. Volcanologists— who are not a species from “Star Trek” but rather scientists who study volcanoes — keep tabs on the amount of magma held within the volcano 's underground reservoir, using tools like seismometers.
That’s how you get magma collecting in reservoirs that can blast to the surface. Volcanoes can form at divergent boundaries, too.Sometimes that happens on land, in places called continental rifts, where two continental plates pull apart from each other, causing hot mantle rock to well upward.
In small doses, volcanic ash is really good for crops. Volcanoes are where we find a lot of our most prized minerals, like gold, silver, copper, lead, and zinc.And the heat of volcanic systems can be tapped for geothermal energy, which we’ll get more into in a later episode.
Well, all right, I'm just going through. Volcanoes are a love of mine.
CO2 isn't one of them. Volcanoes have been doing it forever.
We actually live on a tectonically active planet. Volcanoes could come back at any point, really big mega volcanoes .By the way, Yellowstone is not one of those.
he wrote about this notion that we could put little particles of sulfur high up in the stratosphere, 60,000feet or so, would act like tiny mirrors, essentially doing what volcanoes do. We know from history the volcanoes cool off the planet. Mount Pinatubo which erupted in the Philippines in 1991 lowered the temperature of the Earth for about a degreefor a few years. We know that this works. You put the particles up high in the stratosphere, they reflect sunlight like little mirrors, the sunlight cools things down and the reduction
chance and then it hit them these were not just craters these were giant volcanoes on Mars and so the as the dust cleared the view became spectacular andon the right you see the largest of the Martian volcanoes in fact it's the largest volcano in the entire solar
Because this placid lake formed from a massive volcanic supereruption. The volcano shot out tons of lava and volcanic ash, buckling the earth into a depression about the size of Singapore. Eventually, it filled with water and became Lake Taupō.
repeatedly so we had no choice but to ret treat over to uh a pile of ash from the volcano and start walking down that and when we finally reach the bottom of this lake bed we were caught in an ashstorm so bad that we couldn't see each other a mere 10 ft apart from one another so we took off our shirts and
high. This is taken about 6,000 feet above ground. The volcano is probably 5 miles across and you can see a little pink parachute in kind of the upper left and that's one of my French buddies that was flying with me in the same aircraft that I had.
the most recent big global warming spike in Earth history before today. And it was caused by volcanoes . That's what often caused global warming during the long span of Earth history. In fact, as the volcanoes that still erupt in Iceland today, that started to erupt back then, there are much more powerful back then. There was a lot more lava back then, and all that lava burning through the Earth as the North Atlantic Ocean opens up, lava that actually scoured a whole lot of Scotland, even the field sites. I have sites on the Isle of Sky where they're Jurassic age dinosaurs,
It can also refer to the land formations that build up around those vents, like the mountain-looking things we might think of when we hear the word “volcano .” But volcanoes aren’t just mountains— especially because they erupt. Let’s take a look at how that happens.
You know, so the hobbits have somewhere to chuck that ring. Composite volcanoes erupt with remarkable variety, sometimes unleashing torrents of lava, other times sending up volcanic plumes of tephra that fall back to Earth. These combinations of eruptions build up the composite volcano 's iconic steep flanks.
The result is a huge, bowl-shaped caldera, like Lake Taupō. So volcanoes come in all kinds of shapes and sizes, and you can find them all over the world. But they don’t pop up just anywhere.
Like, some geologists use “active” to refer to volcanoes that are erupting right now, and others use it to mean any volcano that’s erupted in the last 11,000 years or so. Dormant volcanoes aren’t erupting right now but might in the future. And extinct volcanoes were active once, but aren’t expected to erupt ever again— even though they can surprise us once in a while.
We’re talking the sites of some of the biggest earthquakes ever recorded. Massive volcanoes in Indonesia, Russia, even Antarctica. Huge explosions and fractures that happen on land and underwater.
One theory is that volcanic eruptions released gases like carbon dioxide and methane, which made up Earth’s early atmosphere. Those volcanoes could have also released nitrogen and water vapor, which built up in it. Then, as Earth cooled, the water vapor condensed, forming the oceans.
Hi, I’m Sage. And this is Earth. Explosive volcanoes oozing red-hot lava. Gargantuan gorges carved millions of years ago by rushing rivers, and earthquakes that trigger hundred-foot waves.
So first, asteroids. Oh, OK, a few. Super volcanoes , big volcanoes , super-- OK, great. Nuclear war. You guys are smarter than those crowds.
take place, these mass extinctions, is not particularly exciting. Mega volcanoes actually are kind of exciting. Asteroids from space, pretty good on the exciting scale.
But a supereruption is VEI of 8, meaning it ejects at least 1000 cubic kilometers of ash, pumice, and debris. That’s enough volcano -stuff to fill 400 million Olympic swimming pools. The 100-meter butterfly would be… just so different But could this really happen at Yellowstone?
Some aren’t convinced another will ever happen again. And just because a volcano has had one, or even two, supereruptions in the past, doesn't mean its future blasts will be as hefty. Even if a supereruption were going to happen at Yellowstone, we'd have some notice.
Another is to form an evacuation plan and gather emergency supplies like food, water, masks, and clothing. There’s more on volcano preparedness in the links below. So, yeah, volcanic eruptions can be scary.
So sense of scale here, it's a little tricky, and I can't even capture the full thing in one picture without a fisheye lens. This is another classic volcano . And you may think, wow, that would look like Mars, except for the fact that it has an atmosphere that we can see.
And now here is your more stereotypical volcano , just to get the juices flowing a little bit. Because this volcano in the photo is erupting. This is El Reventador volcano in Ecuador, and its name in Spanish means "the eruptor." As you can see, it was happy to oblige
Because this volcano in the photo is erupting. This is El Reventador volcano in Ecuador, and its name in Spanish means "the eruptor." As you can see, it was happy to oblige with an eruption for this shot.
And I can see what the composition of the gases is, and then that also tells us, are we building up to a more explosive eruptive event, or is this volcano likely to just sort of simmer along as it has been? So we get a lot of different information depending on what part of the volcano we're listening to.
It is a dormant volcano , but then there were huge icebergs on the mountain, at the top near the crater.
So maybe a volcano erupted over a beach and that turned into sandstone and granite.
So opposite of that volcano that I showed you, Mauna Loa, it could be another planet.
And a shield volcano against Juniper Lake.
But Wait is a volcano that will never erupt.
And there was a volcano that was erupting in that area.
Just go to the volcano , put the ring in the volcano , and then everything's going to be fine.
And when the volcano on the island began to explode, Georges Hebert hops in his life raft.
It's an extinct volcano in the middle of Africa.
This is my volcano .
That's going on for about 1,000 years. So we have a volcano that is emitting gas and lava into the environment for 1,000 years, roughly. Scientists aren't sure if it started and stopped or if it just kept gushing.
volatility earthquake volcano there are some volcanoes that are so sensitive that the only one degree of pressure or
with the volcano and the geyser, the mysterious medicine spring and the poisoned valley. We toy with the weirdest phenomena of Nature as if they were familiar spirits."
it's a chocolate volcano a muddy volcano okay and then I'm going to frost the
Arizona and its complex of summit calderas is the size of Rhode Island this is a big volcano you have to imagine what it was like for the geologists who had been so far seeing a very moonlike Planet without any signs
This is the highest volcano -- active volcano in the southern hemisphere, umm, or it's the southern most active volcano . It's 13,000 feet high and it's active.
you fight as a volcano representing anger
North Pole to the South Pole. And it was a land mass that was ruled by a lot of early relatives and cousins and ancestors of us distant mammal ancestors. But then, in what is now Siberia, these enormous volcanoes started to erupt about 250 million years ago. And these are not volcanoes like those that we know today. It's hard to even envision what these were like. These weren't the Hawaiian volcanoes or Mount Pinatubo blowing its top one day. No, no, no, these were enormous fissures in the Earth. It's like the Earth was slashed with a giant machete
Dormant volcanoes aren’t erupting right now but might in the future. And extinct volcanoes were active once, but aren’t expected to erupt ever again— even though they can surprise us once in a while. But it’s not all Mount Doom and Gloom living near an active volcano .
But there are ways to forecast and prepare for eruptions. Geologists and volcanologists monitor warning signs of volcanic activity, like earthquakes, swelling in the ground, and steam rising ominously from places it shouldn’t. They also base forecasts on volcanoes ’ recurrence intervals, or the average times between past volcanic eruptions.
And there are underwater volcanoes called seamounts, where violent, submarine, volcanic eruptions built up mountains on the seafloor.
