Hello Leila - For questions on Yellowstone, you should contact the Yellowstone Volcano Observatory: https://volcanoes.usgs.gov/observatories/yvo/ They also have a great FAQ that answers a lot (maybe all?) of your questions: https://volcanoes.usgs.gov/volcanoes/yellowstone/faqs_facts.html Thank you, Cheryl -------- Leila Kramer wrote: Good Afternoon, My name is Leila Kramer and I am working to complete a research project on the Yellowstone Supervolcano. I’m conducting a personal interview, and I have a few questions that I would love for you to answer listed below. Could an earthquake or other natural disaster cause the supervolcano to erupt? Is the volcano still considered active? How many, people would be affected if the volcano erupted today? If it erupted could it affect countries besides America? How easy would it be to prevent the volcano from erupting? Could we use the volcano as a source of clean energy?
