Solfataras
Solfataras are volcanic vents or fumaroles that emit sulfurous gases, steam, and hot mud. These features are typically found in areas of high volcanic activity and are characterized by their strong smell of sulfur and yellow-colored mineral deposits. Solfataras are often associated with geothermal areas and are formed by the interaction of magma with groundwater, leading to the release of gases and steam through cracks in the Earth's surface. These volcanic features can be found in various parts of the world, including Iceland, Italy, New Zealand, and Japan.
