Live seismic monitoring
Mount Etna volcanic tremor live
Volcanic tremor is a continuous seismic signal associated with movement inside the volcanic system. The live value and recent trend help identify changes, but they must be read together with other observations.

What volcanic tremor measures
Unlike an individual earthquake, volcanic tremor is sustained vibration. Its amplitude may be influenced by fluid movement, degassing and eruptive processes. The absolute value depends on the station and processing method, so comparisons are most useful within the same time series.
A rapid increase deserves attention, but it is not a stand-alone eruption forecast. Wind, technical noise and station changes can also affect measurements.
How to interpret the live number
Look at the direction and duration of a change rather than a single reading. Then compare it with webcams, thermal hotspots, earthquakes and the latest INGV bulletins.
Volcanic tremor questions
What is a normal tremor level for Mount Etna?
There is no universal normal value. Levels vary by station and period, so the recent baseline and trend are more informative.
Can tremor predict an eruption?
Tremor can reveal escalation, but it cannot reliably predict an eruption by itself.
Where do the tremor data come from?
EtnaMonitor processes public seismic information associated with the INGV Catania monitoring network and clearly identifies the active station.
Official sources and safety notice
EtnaMonitor combines public data from INGV Catania, NASA FIRMS and aviation authorities. It is an independent information service and does not replace official civil-protection, airport or volcanological bulletins.
