All are the factors of viscosity of lava, except

• Silica (SiO2) content of lava

• Temperature of lava relative to solidification point

• Gas dissolved in Magma

• Density of Magma

It is characterized by gas-driven explosion that propels magma and tephra.

• Explosive Volcanic Eruption

• Effusive Volcanic Eruption

It is the outpouring of lava without significant explosive eruption

• Explosive Volcanic Eruption

• Effusive Volcanic Eruption

The calmest of the eruption types.

• Hawaiian

• Strombolian

• Vulcanian

• Surtseyan

Eruptions driven by bursting gas bubbles within the magma.

• Hawaiian

• Strombolian

• Vulcanian

• Surtseyan

It is an explosive eruption that occurs when the pressure of entrapped gases in a relatively viscous magma becomes sufficient to blow off the overlying crust of solidified lava
