Value: No red aviation codes on major routes
Rated on: No aviation colour code red; no large eruptions.

No eruptions disrupting major air routes

Why it's at this level: No volcano is at aviation colour code red near major air routes and no large explosive eruption was reported in late October (Volcano Discovery, 20 Oct). Kīlauea in Hawaiʻi continues episodic lava fountaining, which does not affect international aviation.

What this means for you: No volcanic disruption to flights at present.

Why it matters: Major eruptions ground flights (Iceland 2010) and can cool the climate for years.
What moves it: Volcanic unrest; impact depends on ash plume height and jet-stream direction.

Rubric — Alert: Major airspace closures from ash, or a VEI 4+ eruption. | Watch: Aviation colour code orange/red at a volcano near major air routes, or a large eruption. | Normal: No aviation colour code red; no large eruptions.
