Potential ash impact from Antarctic volcanoes: Insights from Deception Island’s most recent eruption
Ash emitted during explosive volcanic eruptions may disperse over vast areas of the globe posing a threat to human health and infrastructures and causing significant disruption to air traffic. In Antarctica, at least five volcanoes have reported historic activity. However, no attention has been paid...
