Notice that in the description of elevated status, there are abbreviations such as AVO and HVO. Along the top of this page, next to the Elevated tab, there are more of these abbreviations. These indicate the volcano observatories in the U.S. Go back to the volcano hazards main page (click on “Home” on the left of the page). On the right side of the homepage, there is a list of volcano observatories in the U.S (below the interactive map). How many volcano observatories does the U.S. have? Name them.

What is Yellowstone’s current Advisory Color Code? Green b. Scroll down the page. Under YVO Quick Links, click Yellowstone Volcano Hazards. What are the TWO main hazards to occur within the next few decades? Large and moderate earthquakes and hydrothermal explosions c. Continuing on this page, how many explosive volcanic events has Yellowstone had in the last 2.1 million years? Three immense explosive volcanic eruption d. Yellowstone is famous for its geothermal waters that create hot springs and geysers, but this creates one of Yellowstone’s most dangerous and frequent hazard: hydrothermal explosions. Hover your mouse over this term on the Yellowstone Hazard page and describe what a hydrothermal explosion is. Using what you’ve learned from this unit, describe how the groundwater in Yellowstone becomes heated.
