Considering this, what type of lava is least likely to form a pyroclastic flow?
Subsequently, question is, which kind of magma produces a quiet volcanic eruption? basaltic
Secondly, what type of magma has the lowest viscosity?
Non explosive eruptions are favored by low gas content and low viscosity magmas (basaltic to andesitic magmas). If the viscosity is low, non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.
What type of magma does Mt St Helens have?
Helens is a large eruptive cone consisting of lava rock interlayered with ash, pumice, and other deposits. The mountain includes layers of basalt and andesite through which several domes of dacite lava have erupted.
