Is there any volcanoes in the east coast?
No. The geologic forces that generated volcanoes in the eastern United States millions of years ago no longer exist. Through plate tectonics, the eastern U.S. has been isolated from the global tectonic features (tectonic plate boundaries and hot spots in the mantle), that cause volcanic activity.

What are the 3 super volcanoes in the US?

What will happen if Yellowstone erupts?
What would happen if a “supervolcano” eruption occurred again at Yellowstone? If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate.
How long until the Yellowstone volcano erupts?
Will the Yellowstone volcano erupt soon? Another caldera-forming eruption is theoretically possible, but it is very unlikely in the next thousand or even 10,000 years. Scientists have also found no indication of an imminent smaller eruption of lava in more than 30 years of monitoring.
