S1.16: Seismicity and ground deformation link in volcanic areas: multidisciplinary approaches and joint investigation over different timescales
Multidisciplinary analysis of data coming from different fields, such as ground deformation and seismic observations, represents a successful strategy to investigate the dynamics of volcanoes. The deformation pattern related to fracture processes or induced by fluid mass movements are often associated with the occurrence of seismicity, and the two phenomena can be interpreted in a unified framework. The time scales involved in these processes span from seconds up to tidal periodicity (diurnal, fortnightly, monthly).This main topic of this session is to provide a contribution to the understanding of the link between ground deformation and seismicity. Indeed, joint analysis of tilt and seismic data could evidence the relationships between tilt patterns and the rate and energy of seismicity (earthquakes) also on different time scales.The characterization of the kinematics and evolution of crustal deformation associated with volcano activity could allow a prompt identification of eruptive precursors. In this context, studies concerning the analysis and interpretation of ground deformation are welcome, including tilt meter, GPS, strain meter data as well as seismic signals. Contributions adopting innovative techniques or multidisciplinary approaches are strongly encouraged.
