The two main factors are the viscosity and the gas content of the magma. explosive eruptions usually occur when magma approaches the surface and dissolved gasses bubble out so rapidly that it escapes explosively, creating clouds of ash and pumice. If there isn't enough gas this can't happen. High viscosity magma by definition does not flow easily. This allows pressure to build inside or under a volcano as the magma moves slowly. The higher viscosity also means the magma can hold more gas.
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.
There are two factors that determine how explosive a volcano is. The two factors are the amount of gas that is present in the lava and how easy or difficult that gas can be released into the atmosphere.
The volatile content of the magma. Weather water or Ice has ingres to the volcanic vent. The physical stability of the volcano.
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.
Factors that determine the force of an eruption are magma viscosity and gas content.
