Scientific Program

Special sessions and plenary talks

Advancements in our understanding of the solid Earth and geophysical processes have often been driven by instrument and method developments. Examples include the role of marine geophysical mapping to the development of global plate tectonics, the contributions of broadband seismometers to the understanding of inner Earth discontinuities and earthquake rupture, or the interfereometric techniques for the study small time dependent changes. During the last decades the number of new instruments and methods increased enormously, often without realizing the potential applications in geophysics. The session invites contributions with new and interesting developments from all fields in geophysics and aims to support novel experiments by enhancing discussions and exchange between researchers at all stages of careers.

Seafloor geodesy: Monitoring offshore crustal deformation at mm-scales

Both the number of geological and hydro-meteorological hazards and the severity of their impacts have dramatically increased over the past decades. Cascades of such events or coincidental occurrences have challenged populations causing significant losses. The scientific community has responded with a variety of approaches aimed at monitoring the individual hazards as they unfold, modelling their source properties and propagation, and forecasting their development. Techniques ranging from field experiments to remote sensing, from borehole and ground in-situ stations to UAV and space based methods are used for assessing and understanding natural hazards and their consequences. This session invites contributions that discuss advances in our understanding of natural hazards based on new data, methods and models, identify open questions and present visions for future developments and/or monitoring, with a broad scope emphasizing man-made hazards, earthquake hazards, volcano hazards and mass wasting hazards. We also invite contributions improving and demonstrating the modelling and uncertainty analysis techniques and their applications. This is inherent in the task because we are considering the future occurrence of rare complex phenomena about which data and knowledge are always lacking. We then also encourage studies which are addressing the issue of extreme events and the way to evaluate and communicate hazard/risk uncertainties.

Plenary talk: Warner Marzocchi, INGV Instituto Nazionale di Geofisica e Vucanologie, Roma/Italy:

Forecasting seismic and volcanic hazards: scientific challenges and practical implications

Geophysical tools are increasingly used to study the uppermost tens of meters underneath the Earth's surface. These near-surface environments support our infrastructure and yield much of our mineral and water resources, serve as waste repository, and are most susceptible to human modification. Moreover, basic scientific questions arise from disciplines such as archaeology, geology, hydrology, and soil science. This results in diverse applications, where geophysical tools can help to image subsurface structures, to estimate crucial material properties, and to monitor relevant processes. Here, we welcome state-of-the-art in engineering practice and case studies from all fields of application demonstrating the potential but also the limitations of geophysical surveying. We also invite methodological contributions presenting innovative approaches for acquiring, analyzing, and interpreting geophysical data, which includes the development of novel instrumentation, modeling, and inversion tools.

Plenary talk: Stéphane Garambois, Université Grenoble, France:

Potential and limits of seismo-electromagnetic wave conversion for geophysical imaging

The Earth's system is highly coupled and knowledge on the processes within Earth's components such as core, mantle, lithosphere, but also the hydro- and atmosphere are crucial for understanding their interactions. With the advent of new capabilities in global monitoring through network stations on the ground and in water, with reliable data transmission and sophisticated satellite missions, researchers have now been able to address these different topics. The new data have strongly advanced the power and reliability of global and regional scale modeling based on physical principles, combined with empirical maps or data assimilation. We solicit contributions from data analysts and modelers who focus on large and medium scale processes in either the Earth's components or their interactions.
