What’s inside Mexico’s Popocatépetl? Scientists obtain first 3D images of the whole volcano
The 3D image reveals multiple magma pools at different depths beneath Popocatépetl, aiding eruption response for 25 million people in the surrounding area.
- On Friday, Dec. 5, 2025, Mexico's National Autonomous University produced the first full three-dimensional image of Popocatépetl volcano's interior during their latest expedition.
- Its mission focused on figuring out what is happening under the crater, as earlier scientists who took images 15 years ago produced contradictory, low-resolution results, prompting repeated field campaigns by the research team .
- Using expanded seismograph arrays from 12 to 22 stations, instruments measured ground vibrations 100 times per second and Karina Bernal processed data with artificial intelligence algorithms adapted for volcanic tremors.
- The map will help local authorities tasked with eruption response by providing certainties for repeated analysis and giving residents within a 62-mile radius detailed information about Popocatépetl, which could affect houses, schools, hospitals and five airports.
- Still, researchers face hazards from lahars and other volcanic hazards on the slopes, data loss from explosions and animal damage, and challenges digging up failing stations complicating monitoring.

What’s inside Mexico’s Popocatépetl? Scientists obtain first 3D images of the whole volcano
By MARÍA VERZA POPOCATÉPETL VOLCANO, Mexico (AP) — In the predawn darkness, a team of scientists climbs the slope of Mexico’s Popocatépetl volcano, one of the world’s most active and whose eruption could affect millions of people. Its mission: figure out what is happening under the crater. For five years, the group from Mexico’s National Autonomous University has climbed the volcano with kilos of equipment, risked data loss due to bad weather or…
