Impact of volcanic eruptions on flight routing

This study investigates the impact of large volcanic eruptions on flight routing by analyzing case studies of the 2020 Taal volcanic eruption in the Philippines and the 2022 Bezymianny volcanic eruption in Far East Russia. The research examines flight trajectories before and after these eruptions, focusing on flight cancellations and rerouting patterns. Findings indicate that most flights adhered to advisories issued by the Volcanic Ash Advisory Center (VAAC) when determining whether to proceed, reroute, or cancel. However, variations in response were observed between in-flight adjustments and decisions made during landing or takeoff phases.
