EtnaMonitorNASA FIRMS thermal hotspots, INGV earthquakes and satellite imagery in one interactive view.
Each point indicates a satellite thermal anomaly, not independent confirmation of an eruption. For the operational picture, also check Etna's status.
TheFRPis the radiative power integrated within a pixel, expressed in megawatts. It helps compare detections but does not directly measure overall volcanic activity.
Clouds, viewing geometry and satellite pass times can hide or alter a detection. Read the map alongside tremor, earthquakes and official statements.
No. Points show satellite thermal anomalies. On Etna these can be consistent with lava, hot surfaces or cooling flows, but alone they do not confirm an eruption.
The page checks data every minute, but new detections depend on satellite passes, cloud cover and NASA FIRMS processing times.
Missing points may result from no detected anomalies, clouds, satellite timing or sensor limitations. They do not automatically mean an absence of volcanic activity.
The 24-hour view highlights recent detections; the 7-day view adds the week's history to show persistence and distribution.
