Ash Fall

Ash fall occurs when fine particles of volcanic ash are explosively ejected into the air during a volcanic eruption and then settle back to the ground. These tiny fragments, created by the fragmentation of magma and rocks, can travel long distances with the wind before settling. Ash fall can impact air quality, cause visibility problems, disrupt transportation, damage machinery, and pose health risks to people and animals. The thickness and spread depend on eruption strength, wind conditions, and eruption duration. Typically, ash fall episodes are temporary but can have lasting environmental and economic effects in affected areas.
