El Misti is considered an active volcano, and the persistent emission of sulfurous gases from these fumaroles serves as evidence of ongoing magmatic activity beneath the surface. The volcano's summit reaches an elevation of 5,822 meters (19,101 feet). The presence of the fumaroles is monitored as part of regional volcanic hazard assessment.
