What is Yellowstone Volcano?
Yellowstone is a crater volcano that has experienced three very large explosive eruptions in the past 2.5 million years (Huckleberry Range tuff 2.1 million years ago; Mesa Falls tuff 1.3 million years ago; and 640,000 years ago Lava Creek in front of the tuff). In the past 2.1 million years, several major volcanic events plunged the landscape of Yellowstone Park into a huge crater or depression measuring 55 x 72 kilometers (34 x 44 miles).
The Yellowstone Plateau volcanic field evolved in three volcanic cycles spanning 2 million years, including some of the largest known eruptions in the world. The Yellowstone Crater is a huge crater in the midwest of Yellowstone National Park in northwestern Wyoming. It was formed by a catastrophic volcanic eruption about 640,000 years ago.
Formed by erosion of the Yellowstone River, the canyon is more than 1,000 feet deep, 1,500-4,000 feet wide, and about 20 miles long-it also offers endless views. Diane Rankin, National Park Service, enjoys the views of Lower Falls and the Grand Canyon of the Yellowstone from an artist’s perspective. Overlapping maps of Yellowstone craters, lava flows, and potential hazards (including earthquakes and hydrothermal explosion craters). In 2001, the U.S. National Park Service, together with the U.S. Geological Survey and the University of Utah, established the Yellowstone Volcano Observatory to monitor volcanic and seismic activity in the area.
When will Yellowstone Volcano Erupt?
It is believed that Yellowstone has not had a magma eruption since humans lived in North America. Dubbed the “Restless Giant” due to its geological instability, Yellowstone may someday receive another major eruption, similar to the one that formed its youngest caldera 600,000 years ago.
The most likely scenario for an eruption in Yellowstone is a smaller event that caused lava flows (similar to what is happening now in Icelandic Bardarbung) and a typical volcanic explosion is possible. In fact, it is even possible that Yellowstone will never have such a large eruption again.
Many scientists consider it unlikely that another supervolcanic eruption will occur in the near future in Yellowstone, for example, in the next thousand years.
The new study even showed that if another supervolcanic eruption occurs in the Yellowstone hotspot, it probably won’t happen in another 1 or 2 million years. But even this is not a very good estimate, since there is no certainty that Yellowstone will erupt with a regular cycle or that it is still “late” for another eruption.
The current levels of seismicity, soil deformation and hydrothermal activity in Yellowstone, although high by most geological standards, are likely typical of long periods between eruptions and are therefore not immediate concern.
Scientists have studied the supervolcano in Yellowstone for a long time, and comparing the research results gives us an idea of how things will happen the next time the Yellowstone eruption occurs. The big advantage here is that while the next Yellowstone eruption will change life on Earth for a while, it will still exist, and there will likely be an incredible warning period that needs to be prepared. But we will see why volcanologists at the Yellowstone.
Observatory are not betting on the Big One, which will happen anytime soon (even on a geological time scale), and why civilization as a whole is likely to survive an explosion even if it does. So, we will answer this question right away: no, the large explosive eruption in Yellowstone will not lead to the death of humanity (most of the Yellowstone eruptions are not suitable for this worst-case scenario anyway, but rather are lava flows).
As mentioned earlier, Huangshi volcano has erupted many times in the past two million years, and life still exists on the earth today. The Huangshi super volcano is thousands of times more powerful than ordinary volcanoes, but there have only been three truly powerful eruptions in history.
This volcano is just one of several super volcanoes in the world, having experienced 3 eruptions in the past 3 million years. The third and most recent large-scale volcanic eruption 631,000 years ago resulted in the formation of the current Yellowstone Crater, which is 30 x 45 miles wide.
As the North American Plate has moved westward over the past 16.5 million years, the hotspot that is now under the greater Yellowstone region has left a strip of volcanic sediment on the Snake River Plain in Idaho. About 2.1 million years ago, when the hotspot was in the southwestern corner of what is now Yellowstone National Park, volcanic magma reservoirs filled before eruption, leading to one of the largest volcanic eruptions in the geologic record.
The explosion threw ash and debris into the Mississippi River, spewing more than 6,000 times the volume of material erupted during the 1980 eruption of Mount St. Helena. When the underground magma chamber was empty, the earth above it collapsed and formed the first of the three Yellowstone springs. caldera.
The lava flows from this eruption covered an area the size of Washington, DC, and reached 100 feet in thickness. In northwest Wyoming, in the center of Yellowstone National Park, the seething caldera is the scar of a 640,000-year-old giant volcanic eruption.
Beneath Yellowstone National Park lies a reservoir of hot magma five miles deep, fed by a giant plume of molten rock erupting from hundreds of miles below. Heat is removed from molten rock, which is 4–5 miles below the surface of the park, up to the water table, creating gushing geysers and bubbling hot springs.
Visitors often want to know if the Yellowstone Volcano is about to erupt. Here are three facts …
1) the last super eruption occurred about 640,000 years ago;
2) Scientists observing activities in Yellowstone today say that “nothing unusual is happening now”;
3) a giant eruption must be preceded by important warnings.
It is worth noting that Yellowstone is far from the only supervolcano – geologists have found evidence of at least 47 super-eruptions in Earth’s history. The Yellowstone Supervolcano has produced some of the largest eruptions on Earth.
Yellowstone National Park houses over 10,000 hydrothermal structures: an amazing collection of hot springs, mud pools, fumaroles, travertine terraces and of course geysers. These features are due to the high heat generation of molten rock that fuels volcanic eruptions.
Lowenstern explains that the geysers and hot springs of Yellowstone are a direct consequence of the volcanic system. The Norris Geyser Basin is the oldest hot spring area in Yellowstone, with thermal characteristics dating back 115,000 years.
The magmatic heat that triggers this eruption (and two others that are 2.1 million years old) still feeds the famous geysers, hot springs, fumaroles and mud pots in the park. It is one of the largest known volcanic eruptions and marks Yellowstone as a supervolcano (a term used to describe any volcano erupting more than 240 cubic miles of magma).
The total volume of erupted volcanic material is estimated to be 6,000 times greater than the volume of material erupted during the 1980 eruption.It is believed that the Yellowstone eruption 2.1 million years ago released about 2,450 cubic kilometers of material, and the Yellowstone eruption 640,000 years ago … ago, it is believed to have ejected about 1,000 cubic kilometers of material.
Can Yellowstone Volcano Destroy The World?
Subsequent activities were concentrated in the national park. Another major eruption 640,000 years ago formed the Yellowstone crater we see today. The activity then moved to a smaller area in the eastern island park area of Idaho in the southwest of Yellowstone National Park and triggered another major eruption that formed the crater 1.3 million years ago. About 630,000 years ago, a major eruption occurred in the Yellowstone area. The last eruption of Yellowstone National Park was about 640,000 years ago, which was 1,000 times more powerful than the 1980 eruption of Mount St Helens in Washington State, USA.
The eruption of the Yellowstone supervolcano will cause an agricultural disaster over a very large area. In the event of a super eruption of Yellowstone, the vast expanses of Idaho, Wyoming, Montana and other states will suffocate. Major US cities such as Denver, Salt Lake City and Boise can also be destroyed by eruptions. Real Life Lore goes on to say that the volcano’s lava will destroy virtually everything within a 40-mile radius of the explosion.
Since the volcano is located in an island country, any major eruption could potentially trigger a mega tsunami. Indonesia is no stranger to volcanic eruptions since the 2018 Mount Merapi explosion. The supervolcano of Lake Toba, also known as the “forgotten volcano”, may pose a major threat to the countries of Southeast Asia.
The volcanic lake sits atop a huge volcanic crater that is still considered to be in the “resource” phase. According to the BBC, the volcano Cumbre Vieja on the island of La Palma in the Canary archipelago is “unstable”.
If a volcano beneath Yellowstone National Park erupts, it will lead to global famine and a volcanic winter (cooling of the lower atmosphere). According to UN estimates published by The Guardian, the eruption could leave us enough food for exactly 74 days.
In the event of a Yellowstone eruption, global temperatures could drop by 3-5 degrees Celsius and remain low for many years. If Yellowstone erupts, it will immediately kill approximately 87,000 people in the United States. If the supervolcano beneath Yellowstone National Park ever erupts again, it could jettison ash thousands of miles across the United States, damaging buildings, suffocating crops and shutting down power plants.
If the next major outbreak occurs in our lives, there will obviously be death and destruction, but it will not be enough to destroy the United States or even the western United States. In fact, it is even possible that such a large volcanic eruption will never happen again in Yellowstone Park. However, the scientist warned that the potentially catastrophic Yellowstone volcano will erupt again in the future and may destroy humanity.
The prospect of an eruption is not only daunting, but an average of one person falls into the caldera every year, according to Professor Dartnell. Despite the fact that such eruptions occur approximately every 714,000 years – the lower end of the frequency range – the death toll from this disaster is equal to the expected loss of more than 1000 people per year, averaged from now until the moment the supervolcano finally explodes. Approximately every 100,000 years, somewhere in the world, there is an explosion of a supervolcano, the consequences of which can be fatal.
While ordinary volcanoes can kill thousands of people and destroy entire cities, a supervolcano is believed to claim up to a billion lives and devastate continents. Supervolcano Yellowstone has caused three catastrophic eruptions in the past 2.1 million years; all this long before humans settled in North America.
The most recent occurred 640,000 years ago when 240 cubic miles of volcanic ash, rocks, and pyroclastic materials were formed and ejected in Yellowstone Park as we know it, covering about half of what is now the United States. In the past 2.1 million years, Yellowstone Park has experienced 3 mega-explosive eruptions, with repetition intervals of about 600,000 to 800,000 years. In the history of Yellowstone Park, there have been three such large-scale eruptions: 2.1 million years ago, 1.3 million years ago, and 664,000 years ago. The Huangshi super volcano is thousands of times more powerful than ordinary volcanoes, but only three truly powerful eruptions have occurred in history.
During three giant eruptions that formed the caldera between 2.1 million and 640 thousand years ago, tiny particles of volcanic debris (volcanic ash) covered most of the western half of North America, probably a third of a meter deep, several hundred miles from Yellowstone and several inches. It wasn’t that lava covered everything that could be seen, or that volcanic ash rained hard enough to flood everything. Consider the fact that when Tambora, a volcano much smaller than Indonesia, erupted in 1815, it covered parts of the Indian subcontinent thousands of kilometers away with ash deposits three meters deep and resulted in a “year without summer.” Northern Hemisphere, leading to famine and unrest.
The most likely scenario for an eruption in Yellowstone is a smaller event that caused lava flows (similar to what is happening now in Icelandic Bardarbung) and a typical volcanic explosion is possible. There’s also a good chance that moving tectonic plates in North America have ruled out the possibility of an eruption entirely, forcing the magma hotspot beneath Yellowstone to collide with colder, energy-consuming rocks.
But even this is not a very good estimate, since there is no certainty that Yellowstone will erupt with a regular cycle or that it is still “late” for another eruption. The US Geological Survey also notes that if you just take the last three eruptions, the chance of Yellowstone erupting in any given year is 0.00014%, which is less than the chance of a collision with an asteroid destroying civilization.
The point, however, is that if someone, or in some article or documentary, says that Yellowstone erupts every 600,000 years, you immediately know that they are full of nonsense … With rare exceptions, volcanoes do not accumulate magma with constant speed. (in the few cases where this occurs, the rash can be fairly regular).
So, we will answer this question right away: no, the large explosive eruption in Yellowstone will not lead to the death of humanity (most of the Yellowstone eruptions are not suitable for this worst-case scenario anyway, but rather are lava flows). But before you worry, it’s important to remember that most volcano experts say that a Yellowstone super eruption is likely to happen very far away or never. It has been said (by people who prefer to think of really depressing things) that the Yellowstone Supervolcano, a rock portal the size of Rhode Island, capable of releasing hundreds of cubic miles of earth and ash with 100,000 times the power of a nuclear bomb into the atmosphere, could virtually wipe out civilization on Earth. black fart – it’s too late to explode. The bad news is that the supervolcano will erupt and likely wipe out most of the United States.
But the next eruption is likely to be quite small, just a lava outburst with possibly a little ash. The staff of the Yellowstone Volcano Observatory is keeping a close eye on this and will be able to alert you in advance when the magma chamber fills up to ultra-high eruption capacity. Well, NASA botanists have suggested that we could delay, if not eliminate, any eruption by pumping high pressure water into the magma chamber to cool the volcano.
