  • Chiapas authorities and researchers have expanded permanent monitoring at Chichonal volcano with new seismic, meteorological and ground-deformation equipment.
  • The system includes a GNSS station, a weather station, two broadband seismographs and a hydrophone installed with UNAM researchers.
  • Officials said the data will help determine volcanic alert levels and support community preparedness, protocols and evacuation routes.

Chiapas authorities and scientific institutions are upgrading the monitoring network around Chichonal volcano, adding instruments designed to detect changes in the ground, weather and seismic activity.

The state Civil Protection Secretariat, through its Disaster Prevention Center, coordinated the work with Mexico’s National Disaster Prevention Center, the University of Arts and Sciences of Chiapas and municipal Civil Protection officials in Francisco León.

A GNSS system now measures possible ground deformation near the volcano with high precision. A weather station records rainfall, temperature, pressure and wind speed in real time. Teams also installed two broadband seismographs and carried out preventive maintenance on an existing seismic station.

Working with the National Autonomous University of Mexico’s Institute of Geophysics, specialists activated a hydrophone that provides sound reports and effectively “listens to the inside” of the volcanic cone. Officials also carried out geochemical sampling in the crater lake in mid-August.

Civil Protection said the combined infrastructure and scientific work place Chichonal among volcanoes with permanent, highly instrumented monitoring. The information will guide the level and phases of the volcanic alert system and support safety measures for nearby communities. Ongoing work includes field visits, further analysis and efforts to strengthen public knowledge of scientific and technological monitoring, response protocols and evacuation routes.
