What is an ashfall?
VolcanoesVolcanic ash
Quick Answer
Ashfall is volcanic ash that falls back to the ground after being carried into the atmosphere by an eruption.
The Full Story
Ashfall can blanket towns, farms, roads, and airports, even far from the volcano. The ash is made of tiny shards of volcanic glass and rock, not soft fireplace ash. Wet ash can collapse roofs, clog engines, contaminate water, and damage crops, while dry ash can reduce visibility and irritate lungs and eyes. The amount of ashfall depends on eruption size, wind direction, and particle size.
