Springerville volcanic field is a monogenetic volcanic field located in east-central Arizona between Springerville and Show Low. The field consists of 405 discrete vents covering approximately 3000 km2 and is the third-largest such field in the continental United States; only the San Francisco volcanic field and Medicine Lake volcanic field are larger. The total erupted volume is estimated at 90 km3. The field is located towards the western end of the Jemez Lineament.

Economic resources

The St. Johns carbon dioxide reservoir is located in the northwest part of the Springerville volcanic field and has estimated reserves of 445 billion cubic meters. Effort since the mid-1990s to either extract helium from the reservoir or to ship carbon dioxide to the Permian Basinc for enhanced oil recovery have not come to fruition. A more recent US Department of Energy proposal is to use carbon dioxide from the reservoir as a heat exchange fluid for extraction of geothermal energy from the volcanic field.
