Are any Basin and Range volcanoes active today?
None of the volcanic areas in the Basin and Range Province are actively erupting. The last eruption was hundreds of years ago. However, several areas do show signs of activity, including the release of large amounts of carbon dioxide gas from beneath the surface of the Earth.
Geologically any volcano that has erupted in the last 2000 years is considered active. It can erupt again, but we don’t know when or if it will.
