A small range of effects are expected from future eruptions at The Volcano. Its remote uninhabited location makes volcanic hazards less extreme and is therefore not very hazardous. Ash and rock fragments (tephra) ejected during lava fountain activity are unlikely to be high enough to disrupt regional air traffic. However, they could possibly endanger lower flying aircraft along the northern coastal corridor between Vancouver and Alaska. The closest major air route is about to the east. Volcanic ash reduces visibility and can cause jet engine failure, as well as damage to other aircraft systems.
