Dear colleagues,
We would like to invite you to submit an abstract to the following session "TS3.3 - Studying active faults from the near-surface to seismogenic depth: an open challenge” at EGU General Assembly, which will take place on 23-28 April 2023 - Abstract submission deadline is Tuesday, 10 January 2023, 13:00 CET" -
https://meetingorganizer.copernicus.org/EGU23/session/46229<https://urldefense.com/v3/__https:/meetingorganizer.copernicus.org/EGU23/session/46229__;!!IKRxdwAv5BmarQ!cWQHP_07cbG38pVlKxLTZ4YVLCRS6FHLRBhhlDWH9yp5_Z0aie-_SNEsHLoBE7OU1gMmSiPiM6Ign6zinbouRijQI9Ir$>

The session focuses on research aimed at defining the geometry, kinematics, and associated stress- and deformation fields of active faults, as well as building up tectonic and seismotectonic models, in all tectonic regimes, including volcanic areas. Assessing the geometry and kinematics of faults, a key to seismic hazard assessment can be often challenging due to the possible paucity of quantitative data, both at the near-surface and at seismogenic depths.
Tackling this challenging issue is nowadays possible by combining data from different approaches and disciplines, with the aim of obtaining a more detailed characterization/imaging of single active faults, as well as reliable seismotectonic models. In addition, technological advances in data collection and analysis provide a significant contribution. As an example, photogrammetry and LIDAR-derived models enable collecting a great deal of geological data even in inaccessible areas; these data can then be integrated with field (structural), seismological and geophysical data with the purpose of a better understanding of active faults geometry. Also, the improvement in data processing allows to enhance seismic catalogues in areas with low-level seismicity, as well as collect new and more detailed data from geophysical, geodetic, or remote-sensing analysis.
Contributions dealing with the following topics are welcome: i) active faults, including volcanic areas; ii) classical to innovative multiscale and multidisciplinary geological, seismological and geophysical approaches; iii) new or revised seismological, geophysical, field-and remotely-collected datasets; iv) faults imaging, tectonic-setting definition and seismotectonic models; v) numerical and analogue modelling.
