# Thirty years of ground deformation monitoring at Stromboli volcano

## TL;DR

This paper presents 30 years of ground deformation data from Stromboli volcano, capturing various volcanic and tectonic events.

## Contribution

The study compiles and analyzes a long-term, multi-instrument geodetic dataset for Stromboli volcano.

## Key findings

- The dataset spans 1992–2022 and includes tilt, GNSS, and strainmeter data.
- It captures eruptive activity, paroxysmal explosions, and inflation/deflation cycles.
- A GNSS-derived velocity field is provided for further analysis.

## Abstract

Since 1992, INGV has collected tilt, GNSS (Global Navigation Satellite System) and strainmeter data, for the monitoring of effusive and explosive activity of Stromboli volcano. In this timespan, ground deformations related to eruptive activity, paroxystic explosions, cycles of inflation/deflation and many other phenomena of volcanological and geophysical interest have occurred. The dataset from the permanent geodetic networks spans the period 1992/2022 with a variable sampling rate, depending on the individual instrument: from the daily 3D coordinates of GNSS stations to the 1 Hz data of the strainmeter. The time series of GNSS, tilt and strainmeters data cover the entire spectrum of the volcanic and tectonic events observed at Stromboli. A GNSS-derived velocity field is also provided.
