chemical composition,temperature, viscosity
different chemicals in an erupting volcano's magma affects the temperature, which in turn affects the viscosity, which affects the eruption itself
for example, less silica content in the magma means lower temperature which means the lava cools down faster and hardens faster, which means the viscosity increases, which in turn results in  relatively quiet explosion.

The intensity of the volcano eruption depends on the character and composition of the magma.

Further Explanation:

Magma is formed when the lower crust or upper mantle of the earth is melted. This magma is discharge by a volcano, which is referred to as a vent or opening through which magma is released. Many factors can trigger a volcanic eruption. The major reasons are:

  • The density of the magma
  • Pressure from the gases present in the magma
  • Addition of a newly formed magma into an already filled magma chamber

The intensity of volcanic eruption could be of two types, explosive and quite. There are two primary factors which determine whether the volcanic eruption is quite or explosive named are:

  • Viscosity
  • Content of gases in magma

As the viscosity and gas content of magma is low, then volcanic eruption is less explosive or quite. On the other hand, if the viscosity and gas content is high, then the volcanic eruption is explosive.
