Accounting for faults in PSHA studies is a crucial challenge as it involves a wide spectrum of subjects of a varied community that goes from earthquake field geologists to seismic hazard and risk practitioners, earthquake source dynamic rupture modelers, statistical seismologists and geodynamic experts.
In Malta, at the 2018 ESC General Assembly, the aim is to bring together researchers and PSHA practitioners to discuss field data collection issues and challenges for their integration into PSHA.
The Fault2SHA WG solicits contributions such as:
- field data issues – methodological approaches to identify, model and quantify the seismic potential of faults to be used in seismic hazard analysis, geological/geodetical constraints to estimate present-day slip rates, paleoseismological constraints to estimate the degree of periodicity of major events;
- data vs hypotheses issues – concerning possible fault-to-fault rupture scenarios based on geometrical complexities or on physics-based approaches and/or concerning the earthquake recurrence based on time-dependent processes;
- case-studies – illustrating the evolution of knowledge of a faults system, and the role played by the latest earthquakes in confirming/changing the previous hypotheses; hazard assessments that illustrate the capabilities and critical aspects of faults models in representing real, observed shakings.
We encourage, in particular, presentations focused on specific field laboratories. During the session an overview of the past/ongoing initiatives will be presented as well.
In addition to some invited talks, we are planning a short hands-on presentation of tools for characterising seismicity rates of fault systems.
The hands-on presentations can be nested in Session #14, or given after the end of ordinary sessions. Fill the FORM or contact the conveners if you are interested in this initiative.
