Popocatepetl Volcano in Mexico is currently spewing ash and boulders into the atmosphere and surrounding area.
Popocatepetl Volcano Ash Cloud
The resultant ash cloud can be seen on planefinder.net and the full Apple versions of Plane Finder and Plane Finder HD apps.

CENAPRED (Centro Nacional de Prevención de Desastres), The National Center for Prevention of Disasters in Mexico, have raised the alert status to yellow, the third highest.
The current activity is not a full-scale eruption but locals are watching the rumbling “Popo” nervously.
We will keep tracking the ash cloud on our flight radars – hopefully, aviation will not be significantly affected.
The volcano lies only 70 kilometers SE of Mexico City from where activity can often be seen.
