Mexico City – Popocatépetl, the active stratovolcano located near central Mexico, continues to exhibit ongoing volcanic activity, prompting ongoing monitoring and advisories for potential ashfall. Recent reports indicate volcanic emissions reaching altitudes of up to 22,000 feet (6,700 meters), according to the latest advisories issued by Volcano Discovery.
The ongoing activity at Popocatépetl, which lies 70 kilometers (43 miles) southeast of Mexico City, is a regular occurrence, with the volcano frequently emitting plumes of smoke, gas, and ash. The current emissions are being closely watched by authorities, as ashfall can disrupt air travel and pose health risks to nearby communities. The volcano has been active since 1994, with periodic dome formation and collapse events leading to eruptions, the most recent of which occurred in 2023, according to the Associated Press.
Current Volcanic Ash Advisory Details
The latest Volcanic Ash Advisory (VAA) details emissions extending to 22,000 feet (6,700 meters). Prior to this, emissions were reported at 21,000 feet (6,400 meters). These advisories are crucial for aviation safety, as volcanic ash can damage aircraft engines. The alerts are issued to inform airlines and aviation authorities of potential hazards. The volcano’s activity is monitored through seismic data and visual observations.
Popocatépetl’s History and Significance
Popocatépetl, meaning “Smoking Mountain” in Nahuatl, is the second-highest peak in Mexico, reaching an elevation of 5,393 meters (17,694 feet), surpassed only by Pico de Orizaba. According to Wikipedia, the volcano is linked to Iztaccihuatl to the north by a high saddle known as the Paso de Cortés. The area encompassing both volcanoes is protected as Izta-Popo Zoquiapan National Park.
The volcano’s location near densely populated areas, including Mexico City, makes monitoring its activity particularly important. Approximately 25 million people live within a 62-mile (100-kilometer) radius of Popocatépetl, and an eruption could potentially affect houses, schools, hospitals, and five airports, as reported by the Associated Press. Scientists are working to create detailed 3D maps of the volcano’s interior to better understand magma movement and predict potential eruptions.
Recent Scientific Advances in Monitoring
Researchers have recently made significant strides in mapping the interior of Popocatépetl using advanced seismographic techniques and artificial intelligence. A team led by geophysicist Marco Calò at the National Autonomous University of Mexico increased the number of seismographs surrounding the volcano to 22, allowing for a more comprehensive understanding of subsurface activity. The team utilized AI to analyze seismic signals and create detailed maps of the volcano’s internal structure, revealing where magma is gathering and how the volcanic edifice is being built. What we have is the first detailed map of the volcano’s interior, a crucial step in improving eruption forecasting.
What to Expect Next
Authorities continue to monitor Popocatépetl closely, and further advisories are expected as the volcanic activity evolves. The National Disaster Prevention Center in Mexico is providing ongoing updates and assessments. Residents in nearby communities are advised to stay informed about the latest alerts and follow the guidance of local authorities. The ongoing research efforts to map the volcano’s interior will contribute to improved eruption forecasting and risk mitigation strategies in the future.
