Infrasound Array Dataset of the 2021 Eruptive Paroxysms of Etna Volcano

Area of Science:

• Geophysics
• Volcanology
• Acoustics

Background:

• Infrasound monitoring offers critical insights into volcanic processes and eruptions.
• Local infrasound arrays have proven effective for real-time volcano monitoring over the past two decades.

Purpose of the Study:

• To introduce the first open-access infrasound array waveform dataset from Mt. Etna, Italy.
• To support research and development of early warning systems for volcanic activity.

Main Methods:

• Deployment of a 6-element infrasound array at Monte Conca, Mt. Etna.
• Continuous waveform data acquisition from May to October 2021 during intense eruptive periods.
• Analysis of infrasound data to detect, track, and quantify volcanic eruptions.

Main Results:

• Successfully detected and tracked 39 eruptions from Mt. Etna.
• Distinguished volcanic activity originating from multiple vents.
• Provided a comprehensive dataset for future volcano monitoring research.

Conclusions:

• The open-access infrasound dataset is a valuable resource for volcano monitoring.
• The data can aid in the development of advanced early warning systems.
• This dataset serves as a crucial training tool for scientists in volcanology.
