Authorities in Mexico City said that certain airlines had canceled about twenty flights into and out of the city due to ash spewing from the Popocatepetl volcano outside of the city on Tuesday.
22 domestic and international flights have been canceled, the Mexico City International Airport stated on social media, “due to airplane safety checks having found ashes.”
AFP was able to view the arrivals and departures record from the airport, which indicated delays and cancellations but did not specify the reasons.
Authorities have warned ash is likely to fall in the states of Morelos, Puebla and Mexico, as well as in Mexico City, which lies some 55 miles (90 kilometers) from the volcano.
Following sixty years of inactivity, Popocatepetl erupted in December 1994. Since then, access to the crater has been limited, ascents have been forbidden, and a mountaineering hostel has closed.
Since then, there has been an uptick in activity, and on occasion, people of neighboring rural communities have had to be evacuated.
In May of last year, erupted ashes, gasses, and molten rock, rattling nerves.
Some 25 million people live within a 60-mile radius of the volcano, making it among the most dangerous in the world, though it has not had a massive eruption in more than a millennium.
