The thermal activity of Stromboli has been monitored through the processing of a variety of satellite images with different temporal, spatial, and spectral resolutions. The Figure shows the estimates of radiant power from 06-10-2025 to 03-11-2025, calculated using SEVIRI, MODIS, VIIRS, and SLSTR multispectral images.

In the past week, thermal activity in the summit area has generally been at a low level, with a few isolated moderate thermal anomalies. The maximum thermal flux anomaly is 15.84 MW (VIIRS), recorded on 2025-10-29 12:06:00 UTC.

The latest thermal flux anomaly (1.61 MW, SLSTR) was recorded on 2025-11-03 01:12:00 UTC. However, in the past week, poor weather conditions have often affected the analysis of satellite images.
