Volcanism in New Mexico is not “extinct,” but is dormant. The record of volcanism in New Mexico is continuous over tens of millions of years, and there is no reason to think it stopped magically 3000 years ago with the eruption of several cubic kilometers of basalt (McCartys lava flow, El Malpais).
Which volcano could end the world?
If Yellowstone’s volcano erupted, it would be catastrophic. The eruption would shoot a tower of ash into the air, taller than Mount Everest, covering nearby cities in over a meter of ash and creating giant clouds that would block the sun for decades.
