→An eruption driven by the heat in a hydrothermal systems.
Hydrothermal eruptions pulverise surrounding rocks and can produce ash, but do not include magma.
These are typically very small eruptions
2.Phreatic 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 eruptions pulverise surrounding rocks and can produce ash, but do not include new magma.
3.Phreatomagmatic eruption
→An eruption resulting from the interaction of new magma or lava with water and can be very explosive.
The water can be from groundwater, hydrothermal systems, surface runoff, a lake or the sea.
4.Strombolian and Hawaiian eruptions
→These are the least violent types of explosive eruptions.
Hawaiian eruptions have fire fountains and lava flows, whereas Strombolian eruptions have explosions causing a shower of lava fragments.
5.Vulcanian eruptions
→Vulcanian eruptions 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.
