1. Volcanoes: The most obvious feature associated with vulcanicity is the presence of volcanoes, which are vents in the Earth's crust through which molten rock, ash, and gases are expelled.
2. Lava flows: When magma erupts from a volcano and flows onto the Earth's surface, it forms lava flows. These can vary in size and shape, depending on the viscosity of the magma.
3. Pyroclastic flows: These are fast-moving currents of hot gas and volcanic debris that flow down the sides of a volcano during an eruption. They can be extremely destructive and deadly.
4. Ash clouds: Volcanic eruptions can produce large clouds of ash that can travel long distances and have a significant impact on air travel, agriculture, and the environment.
5. Craters and calderas: Volcanic eruptions can create craters and calderas, which are large depressions in the Earth's surface that are formed when the ground collapses after a volcanic eruption.
6. Hot springs and geysers: Vulcanicity can also manifest in the form of hot springs and geysers, which are created when groundwater is heated by magma deep within the Earth and then rises to the surface.
7. Fumaroles: These are openings in the Earth's crust that emit steam and gases, such as sulfur dioxide, carbon dioxide, and hydrogen sulfide, which are released from magma chambers below.
8. Volcanic rocks: Vulcanicity produces a variety of volcanic rocks, such as basalt, andesite, and rhyolite, which are formed from the solidification of magma and lava. These rocks can be found in volcanic regions around the world.

Geomorphic Features
- Volcanic cones: Conical-shaped hills or mountains formed by the accumulation of volcanic material.
- Calderas: Large, basin-shaped depressions formed by the collapse of a volcano's summit.
- Volcanic domes: Smooth, rounded hills formed by the viscous lava flows of some volcanoes.
- Lava domes: Small, steeper domes formed from highly viscous lava flows.
- Cinder cones: Small, steep hills formed by the accumulation of loose cinder material.
- Volcanic necks: Protrusions of hardened lava that remain after the surrounding rock has been eroded.
- Lava flows: Molten rock that has erupted onto the Earth's surface.
- Pyroclastic flows: Fast-moving clouds of hot gas and ash.
Hydrothermal Features
- Hot springs: Natural springs that release geothermally heated water.
- Geysers: Intermittent hot springs that periodically erupt jets of steam and water.
- Mud volcanoes: Vents that release hot, mud-rich fluids.
Geothermal Features
- Fumaroles: Vents that release steam and other gases.
- Solfataras: Vents that release sulfurous gases.
- Thermal areas: Regions characterized by geothermal heat sources, such as hot springs and fumaroles.
Magmatic Features
- Intrusions: Magma that has solidified within the Earth's crust, such as dikes, sills, and plutons.
- Batholiths: Large, subsurface masses of intrusive rock.
Structural Features
- Volcanic fissures: Linear cracks in the Earth's crust that allow magma to reach the surface.
- Volcanic belts: Linear chains of volcanoes.
- Tectonic plate boundaries: Locations where volcanic activity is concentrated due to the movement of Earth's tectonic plates.
- Volcanic cones: Conical-shaped hills or mountains formed by the accumulation of volcanic material.
