A volcanic eruption is one of the most powerful forces in nature, a seemingly unstoppable phenomenon that can have far-reaching impacts far beyond the area surrounding the volcano itself. When a ...
The volcanic haze contains small quantities of ash, water vapor, sulfur aerosols, and liquid droplets suspended in the air. The main concerns for human health in volcanic haze consist of ash, sulfur dioxide gas (SO 2), and sulfuric acid droplets (H 2 SO 4), which forms when volcanic SO 2 oxidizes in the atmosphere. Volcanic haze can be both an ...
The types of minerals present in volcanic ash are dependent on the chemistry of the magma from which it erupted. Considering that the most abundant elements found in silicate magma are silicon and oxygen, the various types of magma (and therefore ash) produced during volcanic eruptions are most commonly explained in terms of their silica content.
