Minoan Eruption of Santorini
A period of weak to violent eruption characterized by fountain lava.
Strombolian
Bursting of gas bubbles within the magma. moderately explosive eruptions of basaltic magma with moderate gas content.
Strombolian
Consist of intermittent, discrete explosive bursts which eject pyroclastics as high as hundreds of feet into the air in firework-like incandescent rooster-tails
Strombolian
Example of Strombolian
Etna in Italy
Characterized by a tall eruption that reaches up to 20 km high with pyroclastic flow and ashfall tephra.
Volcanian
Pressure of entrapped gases in relatively viscous magma becomes sufficient to blow off the overlying crust of solidified lava.
Volcanian
Usually consist of small volumes of magma, but form vigorous eruption columns made up of highly fragmented ash.
