SM4.2

Imaging, modelling and inversion to explore the Earth’s crust and upper mantle

This session will cover applied and theoretical aspects of geophysical imaging, modelling and inversion using both active- and passive-source seismic measurements as well as other geophysical techniques (e.g., gravimetry, magnetic and electromagnetic) to investigate the Earth’s crust and uppermost mantle. We invite contributions focused on methodological developments, theoretical aspects, and applications. Studies across the scales and disciplines are particularly welcome.

Among others, the session may cover the following topics:
- Active- and passive-source imaging using body- and surface-waves;
- Full waveform inversion developments and applications;
- Advancements and case studies in 2D and 3D active-source imaging;
- Interferometry and Marchenko imaging;
- Seismic attenuation and anisotropy;
- Developments and applications of multi-scale and multi-parameter inversion;
- Joint inversion of seismic and complementary geophysical data;
- Applications of new acquisition systems.
