What it means for flights

Reported ash tops FL140. This band affects local operations — departures, arrivals and climb-outs near the volcano — while typical cruise overflights at FL300+ pass above the reported ash.

Reventador is in effectively continuous eruption: VAAC centres issued 386 ash advisories on 90 of the last 90 days. A new advisory is routine background activity for this volcano, not a sudden escalation — what matters operationally is the reported ash band and drift, not the advisory itself.

Frequently asked questions

Is it safe to fly near Reventador 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 FL140. 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 Reventador?+
Delays and cancellations, when they happen, concentrate at airports inside or under the reported ash band — for this event the nearest scheduled airports are UIO (78 km), OCC (86 km), TUA (98 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.
