Vulcanian
Volcano Learning Zone > Types of volcanic eruption > Vulcanian
Vulcanian volcanic eruptions are noisy and dramatic and are named after Vulcano in the Aeolian Islands. A phreatomagmatic
(steam and lava) eruption occurs first, then a black explosive cloud as the volcano vent is cleared then a final whiter column of ash and gas. Lava bombs are not rounded and are typically made of viscous andesite and dacite which could explain their ragged shapes. A final viscous lava effusion may occur.
Stromboli and Soufriere Hills have both shown this eruption style.
