ash clouds
Airborne eruption debris
Ash clouds are airborne masses of volcanic debris—fine rock particles, glass fragments, and gases ejected during an eruption.
They can rise miles into the atmosphere, disrupting air travel by damaging jet engines and reducing visibility.
The ash cloud from the Icelandic volcano grounded flights across Europe for days.
Ash clouds drift with prevailing winds, depositing gray sediment far from the eruption site.
