- Solfatara (volcano)
Solfatara is a shallow
volcanic craterat Pozzuoli, near Naples, and is part of the Campi Flegreivolcanic area. It is a dormant volcano, which still emits jets of steam with sulphurous fumes. The name comes from the Latin, "Sulpha terra", "land of sulphur", or "sulfur earth". It was formed around 4000 years ago and last erupted in 1198with what was probably a "phreatic" eruption - an explosive steam-driven eruption caused when groundwater interacted with magma. The crater floor is a popular tourist attraction, as it has many fumarolesand mud pools. The area is well known for its bradyseism.The vapours have been used for medical purposes since Roman times.
This volcano is where the thermoacidophilic archaeon "
Sulfolobussolfataricus" was first isolated. The archaeon is named for the volcano, as most species of the genus "Sulfolobus" are named for the area where they are first isolated.
