It depends on the pressure, amount of magma, whether it's on a fault line, and how long convection has been going on to determine how the eruption will be.
The two principal factors that can determine the nature or explosiveness of a volcanic eruption is Temperature and Composition in terms of its water content, mineralogy and volatility.
Factors that determine the force of an eruption are magma viscosity and gas content.
The composition of the magma and the presence of trapped gases are two key factors that determine whether a volcanic eruption will be explosive or quiet. A high gas content and viscous magma can lead to explosive eruptions, while eruptions with low gas content and more fluid magma tend to be quieter.
The volatile content of the magma. Weather water or Ice has ingres to the volcanic vent. The physical stability of the volcano.
A summit eruption can involve explosive activity, but not always. Summit eruptions can also involve effusive lava flows or steady emissions of ash and gas. The specific type of eruption depends on factors such as the magma's composition, gas content, and the volcano's plumbing system.

The explosiveness of a volcanic eruption is largely influenced by the magma's composition and the amount of trapped gases within it. Magma with high viscosity and gas content tends to lead to more explosive eruptions, as the gases can build up pressure within the magma chamber until they are forcefully released.
An explosive eruption can demolish a mountainside within minutes to hours, depending on factors such as the size of the eruption, type of volcanic material ejected, and the stability of the mountain. The force and speed of the explosion can rapidly disintegrate and erode the mountain's structure, causing large-scale devastation.
The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.
In a volcano, the higher the pressure rises before eruption takes place, the more explosive the eruption will be. Some volcanoes seem to be "gentle flow" as a matter of course (like Mauna Loa in Hawaii). Some seem to be explosive as a matter of course (like Vesuvius in Italy). Others manifest both types of eruptions.
Pressure and magma
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
