Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
Silica-rich magma makes an eruption more violent. Liquid rich magma results in a greater explosion as well.
silica-rich magma
Rich in silica
Thick due to high silica content.
Thick due to high silica content.
Magma that is low in silica flows readily and produces dark-colored lava. Therefore magma that is low in silica produces Pahoehoe lava. This is called mafic or basaltic magma.
Magma is a hot fluid from deep within the Earth's crust. The set of magma conditions that produce the most explosive eruptions are high viscosity and the presence of dissolved gases.
