Seismic signals provide information on various natural and anthropogenic events, including but not limited to earthquakes, icequakes, landslides, volcanic activities, atmospheric phenomena, traffic, and wildlife activities. Geodetic signals provide information on surficial changes and subsurface deformation which might be aseismic. When possible, integrating seismic and geodetic analyses allows us further insights into various seismic and aseismic events.
This session solicits presentations that focus on innovative seismic or geodetic methods, and/or new findings on all aspects of solid earth processes. Topics range from observing seismic or aseismic events, to probing mechanisms or physics of natural or induced earthquakes, landslides, magmatic systems, glacial isostatic rebound, etc. Artificial intelligence related methods are especially encouraged.
