A huge volcanic eruption has caused flight cancellations at a popular British hotspot in Italy. The eruption has thrown travel plans into disarray at nearby Catania Airport, one of eastern Sicily's main gateways, where inbound flights have been suspended as clouds of volcanic ash contaminated the surrounding airspace. This top-tier alert indicates that an eruption generating significant ash output is either already in progress or believed to be imminent. Ash from volcanic eruptions represents a serious danger to aircraft, as fine particles can enter jet engines and damage critical mechanical systems. This latest episode follows a similar bout of activity in July, when ash from the volcano likewise disrupted flight operations at Catania.
