Session description:
The scientific community faces several challenges in studying volcanic islands, particularly regarding monitoring a plethora of processes taking place at depth. There is still a need to densify seismic networks in volcanic islands, using a combination of land-based and ocean-bottom seismometers to record the signals associated with volcanic and tectonic processes and automatically or manually detect and classify those signals. 3D images from the shallow crust to the deep mantle are crucial to unraveling the geodynamic processes behind the generation of volcanism. More accurate quantification of temporal changes in the volcanic systems will help forecast potential eruptions and monitor ongoing ones. On top of that, the presence of geothermal systems and induced seismicity from industrial exploration are also critical challenges in volcanic islands due to the system's complexity.

Considering the enormous diversity of interactions in volcanic islands, occurring from the crust to the deep mantle, this session aims to gather a wide range of seismic studies in volcanic islands including, but not limited to:

volcanic monitoring and tracking of magma movement;

machine learning detection and classification of volcanic earthquakes;

characterization and location of volcanic tremor;

3D and 4D seismic imaging, including attenuation tomography;

monitoring using seismic ambient noise;

temporal variations in fast shear-wave polarization;

active and passive source studies to characterize flank instability and landslides;

induced and triggered seismicity in geothermal systems
