New effusive phase, intense spattering at Stromboli volcano, Italy

A new effusive phase accompanied by intense spattering activity started at Stromboli volcano, Italy at 01:20 UTC on August 30, 2024.

According to the INGV Etneo Observatory, a lava overflow was detected in the Sciara del Fuoco on August 30 by surveillance cameras. The overflow began at about 01:20 UTC and was fed by intense activity in the North Crater area.

Although the effusive activity had decreased for a few hours, it increased again late in the morning on the upper portions of Sciara del Fuoco. The lava flow is advancing within a groove that was excavated due to volcanic activity in July. The lava front was at an altitude of 400 – 450 m (1 312 – 1 476 feet).

This activity was associated with multiple landslides descending within the same groove as they headed toward the coastline.

In an update posted at 15:41 UTC, INGV said this new effusive phase is accompanied by intense spattering activity and sporadic ash emissions from the South Crater area.

From a seismic perspective, the average magnitude of the volcanic tremor remains elevated at very high levels. Seismogram analysis reveals seismic signals corresponding to events characterized by the rolling of incandescent blocks along the Sciara del Fuoco. The rate of occurrence and the magnitude of explosion quakes have not shown any significant variations.

Additionally, clinometric data from the Timpone del Fuoco station and high-frequency GNSS data indicate no substantial changes in the deformation patterns.
