Carissimi Soci SGI,
Carissimi Soci Società Associate,
su indicazione del Dott. Alessio Testa (Università di Chieti), vi segnaliamo la Call for Abstracts relativa alla sessione TS3.4 "Sedimentary basins and landscape evolution: new frontiers in tectono-thermal history applications", organizzata nell'ambito dell'EGU General Assembly 2023.
we kindly invite you to submit an abstract to the session TS3.4: Challenges in the characterization of active faults in slow deforming areas
at EGU General Assembly 2023 wihich will be held in Vienna (Austria) from the 23th to the 28th of April 2023.
Session description: Active faults in slow deforming areas (<5mm/yr) constitute a critical hazard for the population not only because they are capable of eventually generating large destructive earthquakes but especially because their longer recurrences negatively impact the social perception of the risk. The characterization of fault systems in these areas is intrinsically more challenging as surface processes may mask the rates of tectonic activity and/or the deformation is diffusely distributed. Ultimately, this can prevent having a proper age control of the faults' activity histories. In recent years, overcoming these issues has implied adapting and combining multiple known methodologies developed for faster faults to these new settings (e.g., multi-site paleoseismological trenching, tectonic geomorphology, structural analysis), as well as developing new modeling tools to approximate fault behavior when field data is scarce or takes a long time to gather (e.g., physics-based modeling, geodetic data). The characterization of fault activity in terms of earthquake occurrence and slip rate, together with the proper treatment of their uncertainties, is of vital relevance for probabilistic seismic and fault-displacement hazard assessments of these regions (PSHA and PFDHA). In addition, active faults of slow deforming settings are critical to evaluate the site-specific seismic hazard for critical facilities (e.g., power plants or dams), as longer recurrence times must be considered.
This session is an opportunity to discover and share new data, advances and approaches of the research focused on characterizing seismogenic faults and their activity in slow deformation settings worldwide. We aim our session to enhance discussion about the future actions in this matter, also among early career scientists. Hereby, we invite contributions from various fields including paleoseismology, geomorphology, geodesy, structural analysis, tectonic geochronology, numerical modeling, as well as fault-based PSHA and PFDHA studies.
The deadline for the abstract submission is the 10th of January 2023.
We are looking forward to receive your abstracts!
