A clear guide to tremor, seismic, gas, and thermal monitoring signals.

Monitoring systems
INGV combines seismic stations, volcanic tremor analysis, deformation sensors, gas measurements, and thermal observations. No single signal is enough on its own; interpretation comes from cross-checking multiple datasets.
What signals mean
Changes in tremor, seismicity, gas composition, or thermal output can indicate evolving activity, but each signal must be read in context. This is why official updates are essential before high-altitude planning.
How to use data for planning
Use monitoring data together with weather and guide briefings. Real-time conditions can modify route limits, meeting logistics, and maximum reachable altitude on the same day.
How to interpret updates correctly
Single indicators can be misleading without context. A temporary tremor increase does not automatically imply escalation, and stable seismic counts do not guarantee unchanged surface access. INGV interpretation relies on trend consistency, cross-signal validation, and operational context. For visitors, this means daily planning should always combine official bulletins, mountain weather, and guide briefings.
Public-facing monitoring pages are useful for orientation but not for autonomous risk decisions in high-altitude terrain. The most reliable method is to use data as a planning input, not as a replacement for field expertise.
What changes in practical planning
Monitoring updates can affect departure windows, maximum reachable altitude, and route alternatives. Build flexible schedules and avoid over-committed transfer chains after mountain activities. If updates arrive close to departure, prioritize safety and route quality over peak altitude targets. Good decision-making on Etna is adaptive: check, compare, brief, then execute with margins.
Final planning notes
Before departure, verify local updates, weather exposure, and route suitability for your group. A guided approach remains the most reliable way to combine safety, learning value, and realistic timing on Mount Etna.
Before You Go: Quick Planning Checklist
- Check updated weather and volcanic activity conditions for your travel dates.
- Confirm meeting point, start time, and transfer duration.
- Book your tour with flexible options when possible.
- Read local safety guidance before excursions.
