JA10 - Electromagnetic Signals Generated by Volcanic Eruptions/Activity, Fluid Pressure, Earthquakes and Aseismic Fault Slip (IAGA, IAVCEI, IASPEI) Description Changes in inter-related crustal stress, deformation, pressure/temperature of electrically conducting fluids and pore pressure in crustal rocks all occur in both volcanic regions and regions of seismic and aseismic fault failure. All these processes generate electric and magnetic (EM) fields. Furthermore, global EM effects are observed in the atmosphere and ionosphere with explosive ash eruptions. While co-eruptive effects and co-seismic fault failure effects in EM fields, deformation, seismicity and geochemistry are readily observed and modeled, the inter-relation between various parameters during periods of volcanic unrest and aseismic activity that are driven by perhaps the same underlying physics is much less clear. This symposium focuses on bringing together examples of multi-parameter land and satellite observations during volcanic activity and earthquake rupture (Part 1), non-eruptive volcanic activity (Part 2) and aseismic fault activity (Part 3) in order to identify the dominant but perhaps changing physical processes involved. Knowledge of the non-uniform EM tomography of volcanoes and fault systems is a necessary prerequisite for modeling these different processes.
