AI-Enhanced Seismic Tomography Maps Two Shallow Magma Reservoirs Beneath Popocatépetl

The AI-driven read of recent CENAPRED seismic records offers a clearer view of the volcano’s shallow plumbing to support stronger hazard monitoring for nearby populations.

Overview

  • UNAM geophysicists used an AI-trained seismic classifier with interferometry to build a 3D tomography that images two near-surface magma reservoirs.
  • The analysis draws on CENAPRED data from 2019–2024, with earlier records added, and is published in the Journal of Volcanology and Geothermal Research.
  • A deeper third chamber proposed by prior studies was not resolved, reflecting the current method’s limited sensitivity at greater depths.
  • The team plans to integrate the AI model into continuous, automated detection to bolster 24/7 operational monitoring by CENAPRED.
  • Researchers will study seismic-wave attenuation to test whether hotter interior zones align with the tomographic anomalies identified by the AI-enabled approach.
