The largest and most violent of all the types of volcanic eruptions are Plinian eruptions. They are caused by the fragmentation of gassy magma, and are usually associated with very viscous magmas (dacite and rhyolite).
What is the strongest type of eruption?
The stronger eruptive types are Pelean eruptions, followed by Plinian eruptions; the strongest eruptions are called “ Ultra-Plinian .” Subglacial and phreatic eruptions are defined by their eruptive mechanism, and vary in strength.
What is the most dangerous type of volcanic eruption?
Not surprisingly, supervolcanoes are the most dangerous type of volcano. Supervolcanoes are a fairly new idea in volcanology. The exact cause of supervolcano eruptions is still debated, however, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion.

Phreatic eruptions pulverise surrounding rocks and can produce ash, but do not include new magma. 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.
