Seismology is fundamental for monitoring and investigating volcanic systems.
Volcanoes are complex systems comprising both time-varying processes and structural heterogeneity. This combination of wide-ranging complex processes, extreme geomechanical heterogeneity, frequently rapid changes in time, leads to challenges in interpreting seismic observations in terms of physical processes at depth. In addition, the link between the variety of physical processes beneath volcanoes and their seismic response (or lack of) is often poorly understood, making it difficult to develop a detailed understanding of the physical processes at work in volcanic systems.
To address these challenges, this session aims to bring together seismologists, volcano and geothermal seismologists, and wave propagation and source modellers working on different aspects of volcano seismology including but not limited to: (i) seismicity catalogues (statistics & spatio-temporal evolution of seismicity), (ii) innovative methods for source locations (iii) source inversions (iv) seismic wave propagation & scattering, (v) small scale deformation studies, (vi) new developments in volcano imagery, (vii) time-lapse studies – including the use of noise, multiplets and high-rate GPS. Studies on geothermal systems in volcanic environments are also welcome.
By considering interrelationships between these complementary seismological areas, we aim to develop a coherent picture of the latest advances, successful applications and outstanding challenges in volcano seismology.
