TYPES OF VOLCANOES based on their ERUPTION

An eruption driven by the heat from magma interacting with water. 

The water can be from groundwater, hydrothermal systems, surface runoff, a lake, or the sea. 

• Phreatic Eruption

• Phreatomagmatic Eruption

• Hawaiian Eruption

• Strombolian Eruption

An eruption resulting from the interaction of new magma or lava with water and can be very explosive.

• Phreatic Eruption

• Phreatomagmatic Eruption

• Hawaiian Eruption

• Strombolian Eruption

These are the least violent types of explosive eruptions whereas explosions causing a shower of lava fragments.

• Phreatic Eruption

• Phreatomagmatic Eruption

• Hawaiian Eruption

• Strombolian Eruption

These are the least violent types of explosive eruptions whereas explosions causing a shower of lava fragments.

• Phreatic Eruption

• Phreatomagmatic Eruption

• Hawaiian Eruption

• Strombolian Eruption

These are small to moderate explosive eruptions, lasting seconds to minutes. Ash columns can be up to 20 km in height, and lava blocks and bombs may be ejected from the vent.

• Phreatic Eruption

• Vulcanian Eruption

• Phreatomagmatic Eruption

• Strombolian Eruption

The most explosive and largest type of volcanic eruptions. 

Eruptions with a high rate of magma discharge are sustained for minutes to hours. 

• Phreatic Eruption

• Phreatomagmatic Eruption

• Plinian Eruption

• Vulcanian Eruption
