Strombolian eruptions consist of intermittent, discrete explosive bursts which eject pyroclasts as high as hundreds of feet into the air in firework-like incandescent rooster-tails. The discrete blasts in this eruption style are caused by vesiculation of the lava at the vent.
What causes strombolian eruption?
Strombolian eruptions occur when gas inside the volcano coalesces into bubbles, called slugs. These grow large enough to rise through the magma column. Once they reach the top of the magma column, they burst because of the lower air pressure, and throw magma into the air.
What is Strombolian and Hawaiian eruption?
Strombolian eruptions involve the complex bursting of gas pockets at the volcanic vent, while Hawaiian eruptions are best described as the fountaining of sustained jets of gas and fluidal pyroclasts.
