Volcanic ash is currently reported in the atmosphere from Kilauea (advisories by VAAC WASHINGTON), with ash up to FL180, intersecting the PHZH flight information region. ADS-B shows 86 aircraft within ~100 km of the volcano in the last 24 h of the latest update — traffic continues around the advisory area.

What it means for flights

Reported ash tops FL180. This band affects local operations — departures, arrivals and climb-outs near the volcano — while typical cruise overflights at FL300+ pass above the reported ash.

VAAC centres issued 12 ash advisories for Kilauea on 6 of the last 90 days.

The monitoring observatory (hvo) currently holds Kilauea at aviation colour code ORANGE. Colour codes describe the state of the volcano itself and are typically raised during unrest, before ash is observed — see the volcanic ash threat guide.

Nearest scheduled airports: ITOHilo International Airport (42 km); MUEWaimea Kohala Airport (76 km); KOAEllison Onizuka Kona International Airport at Keāhole (87 km); HNMHana Airport (170 km); OGGKahului International Airport (202 km). Distances are straight-line proximity, not an impact assessment.

Frequently asked questions

Is it safe to fly near Kilauea right now?+
Commercial operations continue around active volcanoes under procedures defined by aviation authorities and the VAAC system: aircraft are routed around and above reported ash, and airports in the ash band adjust operations as needed. Reported ash tops FL180. This band affects local operations — departures, arrivals and climb-outs near the volcano — while typical cruise overflights at FL300+ pass above the reported ash. Specific flight-safety determinations are the responsibility of operators and authorities — this page reports the published advisory picture, it is not operational guidance.
Will flights be delayed or cancelled because of Kilauea?+
Delays and cancellations, when they happen, concentrate at airports inside or under the reported ash band — for this event the nearest scheduled airports are ITO (42 km), MUE (76 km), KOA (87 km). Overflights at cruise levels above the band normally continue. Check your airline and airport for schedule status; this page shows the advisory and airspace picture behind those decisions.
Where does this data come from?+
Ash geometry and flight levels come from the responsible Volcanic Ash Advisory Centre (VAAC WASHINGTON) bulletins; volcano state from the monitoring observatories' aviation colour codes; traffic figures from ADS-B telemetry aggregated by FlySafe. All upstream sources are public.
