major types of volcanic eruptions Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.

A Pelean eruption is a type of volcanic eruption characterized by the violent expulsion of incandescent ash clouds or blasts. These eruptions are associated with explosive outbursts that generate pyroclastic flows, which are dense mixtures of hot volcanic fragments and gas.12

The term "Pelean" is derived from Mount Pelée on the Caribbean island of Martinique. In 1902, Mount Pelée experienced a destructive eruption that killed approximately 30,000 people and destroyed the port of Saint-Pierre. The fluidized slurries produced by Pelean eruptions are heavier than air but have low viscosity, allowing them to flow down valleys and slopes at high velocities, making them extremely destructive.32
