Strong paroxysmal event at Stromboli summit craters causes pyroclastic flow, Italy

A notable paroxysmal eruption occurred at Stromboli’s summit craters at 12:07 UTC on July 11, 2024, producing an eruptive column and pyroclastic flow along the Sciara del Fuoco.
The flow reached the coastline and extended several meters into the sea, concluding around 12:10 UTC.
Seismic data from Stromboli stations indicated a seismic transient beginning at 12:07 UTC, associated with a sequence of explosive events lasting approximately 8 minutes.
The most energetic event occurred at 12:08:50 UTC, linked to the paroxysmal activity at the summit craters. The average amplitude of the tremor reached a very high level during the paroxysmal event, followed by a rapid decrease to the current medium level.
Observations by INGV personnel and surveillance cameras confirmed the occurrence and characteristics of the event. The permanent deformation monitoring networks, including clinometric and GNSS station sensors, did not show significant variations, indicating stability in the deformation measurements despite the intense activity.
The Aviation Color Code was raised from Orange to Red at 12:30 UTC.

A similar event took place at the volcano on July 4, 2024, resulting in the Department of Civil Protection raising the alert level for the volcano from Orange to Red and transitioning to the pre-alarm operational phase.
