An explosive eruption is primarily driven by the accumulation of gas pressure within magma beneath the earth's surface. As magma rises, the decrease in pressure allows dissolved gases, such as water vapor and carbon dioxide, to expand rapidly, leading to an increase in volume. When the pressure exceeds the strength of the overlying rock, it results in a violent release of gas and magma, culminating in an explosive eruption. Factors such as the viscosity of the magma, the amount of gas it contains, and the geological setting also play crucial roles in determining the eruption's explosiveness.
What else can I help you with?
Can non explosive volcanoes have pyroclastic flows?
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 .
Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
Was the eruption of Fuego gentle or explosive?

How the composition of magma determines an eruption's characteristics?
Silica(te) rich magma is usually an explosive eruption. The explosiveness of an eruption depends on - a) Gases trapped within the magma at eruption b) The Silica content c) The fragility of the crater walls and/or the volcanic plug.
