902 Questions
Is the Yellowstone volcano active dormant or extinct?
It is a super massive semi-dormant/semi-active volcano. It has erupted in the past on about a 150,000 year cycle. While it has been over 150,000 years since the last eruption, there is a tremendous amount of geothermal activity within the boundaries of the park and the surrounding area. There is great concern among geologists that the caldera will erupt again, and if it does, it would be the greatest natural disaster in recorded human history, likely wiping out more than half of the population of the US, and affecting life on a planetary scale.
What would happen if the super volcano under Yellowstone park erupted?
If a supervolcano were to erupt the entire region around the volcano, especially areas downwind, would be devastated. Large areas would be scorched by pyroclastic flows and an even larger area would be covered in falling ash. Cars and planes would be rendered inoperational. Roofs would collapse from the weight of the ashfall. People and animals would suffocate. Toxins in the ash would kill plants. Sulfur emissions would lower temperatures worldwide, causing crop failures and leading to mass famine. We may see another "Year Without a Summer" or even several in a row. It would be the single worst catastrophe in human history.
What type of volcano is under most of Yellowstone National Park?
The Yellowstone Caldera, also known as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano estimated to be an area of about 34 X 45 miles (55 X 72 km).
What type of volcano is the Yellowstone volcano?
One of only a dozen "super volcanos" in the world. When super volcanos explode it changes life on earth. The last time one went off was Mt. Toba 70,000 years ago.
In more technical terms, the Yellowstone volcano is a caldera. Most Caldera volcanoes start out as stratovolcanoes, but this one appears to be an exception.

Did the Native Americans name the Yellowstone area?
Each tribe had its own name for the Yellowstone area, many of them referring to the yellow earth and rocks of the region.
In Hidatsa, the term was mitsiadazi (mi' = stone, tsi = yellow, azi or adazi - river).
The Yellowstone river was called Elk River (Iichíilikaashaashe) by the Crows; the words for elk and for yellow are very similar in Crow, so it is possible that early explorers mistranslated the term as "Yellow River".

How long does it take to drive from Los Angeles California to Yellowstone national park?
It takes about 19 hours and 30 minutes with traffic.
Will yellowstone erupt more in the future because of plate tectonics?
There is no way of knowing, but it is not very likely. Unlike most volcanoes, the Yellowstone volcano is the result of a hot spot rather than a plate boundary. Even if plate tectonics did alter the behavior, the change would take place over the course of millions of years.
