Sagot :
Answer:
Vulcanian eruptions are propelled by exsolution of volatiles in magmas beneath a solidified plug of lava. They may also have a phreatomagmatic component. Vulcanian eruptions usually consist of small volumes of magma, but form vigorous eruption columns made up of highly fragmented ash.
characteristics. The Vulcanian type, named for Vulcano Island near Stromboli, generally involves moderate explosions of gas laden with volcanic ash. This mixture forms dark, turbulent eruption clouds that rapidly ascend and expand in convoluted shapes.
1 capitalized : of or relating to Vulcan or to working in metals (such as iron) 2 : of or relating to a volcanic eruption in which highly viscous or solid lava is blown into fragments and dust.
What is the possible causes of vulcanian?
The pressure of entrapped gases in a relativel viscous magma become sufficient to blow off the overlying crust of solidified lava.
What is the characteristics of vulcanian?
Moderate explosions of gas laden with volcanic ash. This mixture forms dark, turbulent eruption clouds that rapidly ascend and expand in convoluted shapes.
What happens when Vulcanian eruption?
A dense cloud of ash-laden gas exploding from the crater and rising above the peak. They usually commence with phreatomagmatic eruptions which can be extremely noisy due to the rising magma heating water in the ground.
What is the meaning of Vulcanian?
relating to a volcanic eruption in which highly viscous or solid lava is blown into fragments and dust.
