Volcanic ash from Popocatépetl volcano observed at 6 100 m (20 000 feet) a.s.l., Mexico

Volcanic ash from Popocatépetl in Mexico was observed at 6 100 m (20 000 feet) above sea level at 08:21 UTC on March 26, 2026. The advisory was issued by the Washington VAAC at 08:43 UTC.

Satellite data (GOES-19), Mexico City MWO, and webcam imagery confirmed dense volcanic ash plumes reaching flight level FL200, which equates to 6 100 m (20 000 feet) above sea level. The main ash cloud was detected moving southwest from the summit at approximately 18 km/h (11 mph). Additionally, a second dense ash plume at FL250, which is 7 600 m (25 000 feet), was observed moving northeast from the summit. No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report, eruptive activity at Popocatépetl continued during March 11–18, 2026. Ash plumes were observed rising as high as 6 700 m (22 000 feet) above sea level, and drifting northwest and northeast. The public was advised to remain at least 12 km (7.5 miles) away from the crater due to ongoing volcanic hazards.

Popocatépetl is a large stratovolcano located approximately 70 km (43 miles) southeast of Mexico City and 40 km (25 miles) from Puebla. Known hazards include ashfall, pyroclastic flows, and lava domes, which can impact densely populated surrounding regions. Cities such as Amecameca, Puebla, and Mexico City may be affected by future eruptions, depending on wind and eruption dynamics.
