The explosive eruption has got to be powerful enough to create an eruption column (a Jet of hot gas and magma particles). This is shot into the atmosphere by the force of the eruption but the weight of the stuff in the eruption column is so great that it collapses back down on itself under gravity and runs down the sides of the volcano as a pyroclastic flow.
The water is vaporized and the tissue is burned.
a massive avalanche of hot glowing rock flowing on a cushion of intensely hot gases can travel to 200 k m/ h
The answer is Explosive . It is explosive because during a explosive eruption there are clouds of ash, gas , and rock , and with a pyroclastic flow there is dust and ash . there for the answer must be explosive .
Lava flow.
No. A "quiet" eruption will produce lava flows. Pyroclastic flows generally result from explosive eruptions.
No. A lava flow usually indicates an eruption that is not explosive.
Lava flow.
Lava flow.
an explosive volcano will usually have a pyroclastic flow
The name of the explosive outflow of gas from a volcaic eruption is a Pyroclastic Flow, however it can also be called a Pyroclastic Surge.
Lava can't flow violently. Highly explosive eruptions such as the 1980 eruption of Mount St. Helens do not produce lava flows: they produce clouds of ash, gas, and pumice. Mount St. Helens has produced "quiet" lava flows at times.
