Mount Etna geological and seismic activity

Overview

Researchers from the National Institute of Geophysics and Volcanology (INGV) and the University of Milano-Bicocca have completed a study reconstructing 160 years of morphological changes at the summit of Mount Etna. By integrating datasets ranging from 1865 military maps to modern satellite and drone imagery, the study documented the volcano’s transition from a single Central Crater to its current state of four active summit craters: Voragine, Bocca Nuova, the North-East Crater, and the South-East Crater.

Following this geological reconstruction, seismic activity was recorded on the western flank of the volcano on October 18, 2026. The INGV reported a seismic swarm near Bronte, including a peak tremor of 3.2 magnitude at a depth of approximately 6 kilometers. This event was part of a series of tremors ranging from 1.0 to 3.2 magnitude recorded throughout the morning.

    Mount Etna summit evolution reconstructed over 160 years

    A study by INGV and the University of Milano-Bicocca uses photogrammetry to reconstruct 160 years of Mount Etna's summit evolution, tracing its change from one central crater to four active ones.
