Flights on American and United headed to Mexico City Tuesday morning are being temporarily diverted to other nearby airports in Mexico, due to activity and ash fall from the nearby Popocatepetl volcano.

El Popo, as the volcano is known, has been emitting gases and belching smoke and ash intermittently for several weeks in its latest period of activity.

Mexico's National Center for Disaster Prevention reported 64 emissions of steam, ash and gas in the last 24 hours.

Mexico City's Benito Juarez Airport tweeted that the two U.S. carriers are the only airlines to redirect their flights at this time. Other airlines continue to land and takeoff as normal.

There is no presence of volcanic ash in the passenger terminals, according to news reports.
