Yellowstone Caldera

Yellowstone Caldera

The Yellowstone Caldera is a volcanic caldera and supervolcano in YellowStone National Park. It is located in the Western United States and it is sometimes referred to as the yellowstone volcano. It is approximately 34 by 45 miles long. The Lava Creek eruption happened about 630,000 years ago, which made the Yellowstone Caldera and the Lava Creek Tuff form. Light, hot, magma,from the mantle rises towards the surface from the Lava Creek tuff. According to, 3.8 million visitors have visited Yellowstone park since the end of September. Little do these people know the kind of destruction that this volcano can cause.

If Yellowstone is a volcano how often does it erupt? But, first you should know , the differencce between a valcanoe and a caldera is A caldera is formed when a large eruption of magma, or lava, leaves a gigantic empty chamber underground.The Caldera has eruptions once every 600,000 to 800,000 years. Three giant eruptions have occured in the last 2.1 million years. So are we due for another eruption in the near future? The last huge eruption is thought to have occurred around 640,000 years ago, but that doesn’t really mean we’re in line right now for another eruption.

The ash and residue of the eruptions that already happened affected many people that live near. A Yellowstone eruption simulation from, the journal Geochemistry, Geophysics, Geosystems by hydrologist Larry Mastin, revealed that more than one metre of volcanic ash would cover areas that surrounded the volcano. It would affect the entire United States if it erupted again, damaging buildings, smothering crops, and shutting down power plants. The ash in the air is also bad to breathe. The States it would affect most would be Idaho, Montana, Utah, and Wyoming. However, the probability of a large caldera-forming eruption  in the next few thousand years is pretty low.

An injection of huge volumes of volcanic gases gets released into the atmosphere when the Caldera Erupts and it could drastically affect the global climate.The Yellowstone volcanic system shows no signs that it is going to have an eruption right now. The probability of a large caldera-forming eruption within the next few thousand years is super low. So, we could have an eruption in the future but, it isn’t likely to happen or happen soon.
