What does solfatara mean?
A solfatara is a volcanic vent or area of vents that releases gases rich in sulfur compounds. It is a specialized form of fumarole, distinguished by the sulfurous character of its emissions, and is often associated with barren ground, mineral deposits, and the strong smell of sulfur. The word is used mainly in geology, volcanology, travel writing, and descriptions of active volcanic regions such as the Solfatara crater near Naples. It is not a general synonym for every volcanic opening: a vent emitting only steam may be called a fumarole without necessarily being described as a solfatara. For a general audience, “solfatara” is especially useful for understanding the distinctive landscape created by sulfur-bearing volcanic activity.
nounA fumarole or volcanic vent that emits gases, especially sulfurous vapours. The term is often used for an area of such vents in a volcanic region.
- A fumarole or volcanic vent that emits sulfurous gases, especially in areas of volcanic activity.
- A volcanic area containing such vents, often marked by sulfur deposits and barren, mineral-rich ground.
"The trail led across a barren solfatara filled with the smell of sulfur."
"Scientists approached the solfatara cautiously, carrying instruments to measure the rising gases."
"The solfatara fields were almost colourless, but their sulphur-smelling steam revealed the presence of volcanic activity."
“Solfataras” is the common English plural, while “solfatarae” is used in some formal and older geological writing.
"Several solfataras can be found along the volcanic ridge."
A solfatara is a volcanic vent whose name points to sulfur: the word is associated with the Solfatara crater near Naples, one of the most famous fumarolic areas in Italy.

Where does solfatara come from?
The word comes from Italian solfatara, a name associated with the Solfatara volcanic area near Naples. It ultimately relates to sulfur and the Latin word sulphur. English adopted the term in the nineteenth century in geological descriptions of sulfur-emitting volcanic vents.

How solfatara is actually used
The word is chiefly used in geology, volcanology, and descriptions of volcanic landscapes. It is more specific than “fumarole” because it normally implies the presence of sulfurous gases.
Easily confused with solfatara
A fumarole is a general term for a volcanic opening that releases steam and gases, whereas a solfatara specifically emits sulfurous gases or vapour.
