Yellowstone Supervolcano facts

While investigating facts about Yellowstone Supervolcano Map and Yellowstone Supervolcano Eruption, I found out little known, but curios details like:

In 2015, a top Russian Military Strategist recommended dropping a Megaton-Class Nuclear Bomb on Yellowstone National Park, catalyzing a Supervolcano Eruption that could kill more than 50% of the U.S. population in the first 24 hours. He recommends such action if "tensions should ever boil over".

how big is the yellowstone supervolcano?

America's own supervolcano - at Yellowstone National Park - is rocking in one of the largest earthquake swarms ever recorded there. It's super-eruptions tend to occur every 600,000 - 800,000 years; last one was 600k ago.

When was the last time the supervolcano at yellowstone erupted?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what would happen if the yellowstone supervolcano erupted. Here are 23 of the best facts about Yellowstone Supervolcano Eruption 2020 and Yellowstone Supervolcano Threat Level I managed to collect.

when is the next supervolcano eruption at yellowstone?

1. There are scientists at the Yellowstone Volcano Observatory that monitor the area for signs of a possible eruption. Most scientists believe that if a major eruption were to occur there would be weeks, if not longer, of warning signs to alert them, which would give ample time for evacuation.

2. Despite the estimated damage that would be caused if the Yellowstone Supervolcano were to erupt, experts believe that there is only a 1 in 700,000 chance each year that it will happen. This means it is extremely unlikely that it will happen.

3. The last three supereruptions of the United States occurred 640,000 years ago, 1.3 million years ago, and 2.1 million years ago.

4. In 1985 there were 3000 earthquakes at the Yellowstone Supervolcano in several months. This is called a swarm.

5. Cities within 300 miles of the Yellowstone Supervolcano would be covered in as much as three feet of ash if it erupted. Cities as far as New York City and those in Southern California would likely only see a fraction of an inch of ash.

6. The eruption that occurred 1.3 million years ago is called the Mesa Falls eruption. This eruption created the Mesa Falls Tuff and Henry's Fork Caldera.

7. If the Yellowstone Supervolcano were to erupt the gas haze over the United States would cause a drop in temperatures. This would not only result in lost crops, but it would also result in food shortages.

8. The hydrothermal (heated water) features of Yellowstone National Park are evidence that the volcano beneath the park is still active.

9. An eruption at Yellowstone Caldera would result in air traffic being shut down, and communication would be affected as well.

10. If the Yellowstone Supervolcano were to erupt it is estimated that it would be more than 1000 times as powerful as the eruption of Mount St Helens in 1980.

Why is yellowstone a supervolcano?

You can easily fact check why is yellowstone considered a supervolcano by examining the linked well-known sources.

It is estimated that the Lava Creek eruption that created the Yellowstone Caldera ejected 240 cubic miles of volcanic ash, dust, and rock into the surrounding sky.

Scientists recently discovered a supervolcano under Antarctica, and although they believe it is of similar scale as Yellowstone, uncertainty remains as to the consequences of a potential eruption. - source

The Yellowstone Supervolcano experiences approximately 1000 to 2000 earthquakes a year but most are less than a 3 magnitude.

If Yellowstone National Park's supervolcano erupted, almost all the U.S. could be covered in ash.

The eruption that occurred 640,000 years ago is called the Lava Creek eruption. This eruption created the Lava Creek Tuff and the Yellowstone Caldera.

When yellowstone supervolcano eruption?

The eruption that occurred 2.1 million years ago is called the Huckleberry Ridge eruption. This eruption created the Huckleberry Ridge Tuff, and the Island Park Caldera.

How big would the yellowstone supervolcano eruption be?

As recent supervolcanoes go, the Yellowstone hotspot isn't that large. Several more recent eruptions eclipse it in size, and it's eruptions seems to be getting smaller over time.

(Happening now) Scientists are saying there's an actual 10% chance Yellowstone's supervolcanoe will erupt very soon.

Yellowstone National Park in Wyoming is centered over the Yellowstone Caldera, the largest supervolcano on the continent. It experiences between 1000 & 2000 measurable earthquakes each year

Yellowstone National Park is actually laying on top of an active supervolcano. It erupted 640,000 years ago with ash bed covered the western half of where the U.S. is current at. If a full scale eruption occurs again, the end result can be a worldwide catastrophe.

Yellowstone National Park is a Supervolcano, and the Largest Active Volcano in the World
