How do volcanic ash clouds affect airplanes and airport safety?
Quick Answer
Volcanic ash can damage jet engines, scratch cockpit windows, and reduce visibility. Because ash can melt inside engines, aviation authorities often reroute or ground flights near eruptions.
The Full Story
Volcanic ash is not soft dust; it contains tiny jagged particles of rock and glass. When sucked into a jet engine, the particles can melt in the combustion chamber and then solidify on turbine blades, potentially causing engine failure. Ash can also abrade windows and sensors, contaminate air systems, and reduce visibility around airports. The 2010 Eyjafjallajökull eruption in Iceland disrupted air travel across much of Europe for days. Aviation agencies use satellite imagery, pilot reports, and ash dispersion models to keep aircraft away from hazardous clouds.
