Dangerous Volcano Popocatepetl threatens to spread ash over Mexico City Airport

The Big One Looms

While recent disruptions are concerning, the USGS says Popocatépetl could unleash way more power. Its last huge blowout was in 800 A.D., and a similar blast today would put hundreds of thousands of people in immediate danger.

Popocatépetl: A Looming Concern for Travelers to Mexico City

Mexico City, a vibrant metropolis steeped in history and culture, is a popular destination for tourists around the world. However, one can’t ignore the potentially disruptive force lurking not too far away – the active volcano Popocatépetl. Known affectionately as “Don Goyo”, this smoldering giant has the potential to throw air travel and daily life in the region into chaos.

Mexico’s iconic Popocatépetl volcano has been a force to reckon with since 1994. This smoldering giant has a history of kicking up a fuss, with past events serious enough to evacuate thousands (like in 2000). Spring break 2023 was no exception – ash spewed out, causing airport closures (even in Mexico City!), school shutdowns, and locals needing temporary shelter.

Why Planes Fear the Ash

Don’t underestimate that ash cloud! The U.S. Geological Survey warns it’s like tiny, jagged rocks for aircraft. This volcanic grit can wreck jet engines and sandblast plane surfaces, making flying a major risk.

Understanding Popocatépetl

Popocatépetl, meaning “Smoking Mountain” in the Nahuatl language, is one of the most active volcanoes in Mexico. Located roughly 45 miles southeast of Mexico City, it frequently produces steam, gas, and ash emissions as part of its ongoing activity. More concerning are the larger explosions periodically experienced, sending plumes of ash miles into the sky.

How Eruptions Disrupt Travel

Volcanic ash may look light and fluffy, but it’s composed of tiny, jagged particles of rock and glass. This ash poses serious threats to aircraft:

  • Reduced Visibility: Ash clouds can significantly obscure a pilot’s vision, posing safety risks during crucial takeoff and landing phases.
  • Engine Damage: The abrasive nature of ash can damage jet engines, potentially leading to in-flight failures.
  • Communications Disruptions: Ash can interfere with an aircraft’s radio communications, making it difficult to communicate with air traffic control or in the event of an emergency.

When volcanic activity ramps up, authorities prioritize safety by grounding flights at Mexico City’s international airport. Depending on the extent and direction of ash dispersal, these disruptions can lead to flight delays, cancellations, and even airport closures for extended periods.

The Severity of Potential Disruptions

The severity of travel disruption caused by Popocatépetl depends on several factors:

  • Size of the eruption: Larger volcanic eruptions produce more ash, impacting a wider area and for longer durations.
  • Wind Direction: Prevailing winds play a key role in carrying the ash cloud. If they blow towards Mexico City, the impact on air travel will be more significant.
  • Government Response: Aviation authorities will likely set strict thresholds for ash density, determining when it’s safe for planes to operate.

Staying Informed

To stay ahead of potential disruptions when planning travel to Mexico City, follow these resources:

  • CENAPRED (National Center for Prevention of Disasters): (gob.mx/cenapred). Mexico’s official authority provides volcano monitoring and warnings.
  • Volcanic Ash Advisories: Monitor aviation authorities for volcanic ash advisories affecting airspace near Mexico City.

A Force of Nature to Consider

While the chances of a massive, travel-halting eruption are statistically low, it pays to be aware of Popocatépetl’s potential impact on your Mexico City travel plans. Building flexibility into your itinerary and purchasing travel insurance that covers disruptions due to natural disasters can provide added peace of mind. Despite a sometimes-grumpy neighbor, Mexico City remains a fantastic destination, and understanding the risks posed by Don Goyo will help ensure a safer, less-disrupted trip.
