a viscous eruption
silicon dioxide
If an eruption is quiet, it typically indicates that the magma has low viscosity due to high silica content. The high silica content causes the magma to be more fluid, allowing gases to escape easily and resulting in a gentle eruption with less explosive activity.
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
Crazy
The magma of all volcanoes contains silica. The 1991 eruption of Mount Pinatubo involved dacite magma, which has a high silica composition.
It is called silica. silica is poisonous but completely nontoxic.
The high the silica content, the explosive and the eruption.

The concentration of silica and water content in magma influence the force with which it is ejected from a volcano. The higher the levels of water and other gasses as well as the more silica it contains, the more explosive the eruption will be.

If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
