Surface faulting is a common occurrence for crustal earthquakes and is a relevant source of localized hazard to buildings and infrastructures. Fault displacement may occur on the seismogenic plane (primary or principal fault) and on other structures (secondary or distributed faulting) in the vicinity of the primary fault.

After the successful 6th Fault2SHA meeting held in Chieti on 19-20 January 2023, acknowledging the need of common efforts on this topic, we decided to create within the Fault2SHA Working Group the Thematic Fault Displacement Hazard Lab.

Key Questions
- Which parameters influence the surface expression of fault rupture?
- How to integrate geological, geodetical and modeling data to evaluate the hazard posed by principal and distributed faulting?
- Which kind of information is required by stakeholders (e.g., land planners, risk managers, managers of critical infrastructures)?
- How to properly quantify the rupture hazard?
Specific Aims
- Create a research group at European level interested in the topics of earthquake surface rupturing and fault displacement hazard analysis.
- Attract the interest of researchers working in different disciplines (geology, geodesy, fault modelling, hazard modelling) to create an interdisciplinary group.
- Promote research topics in FDH for PhD students and provide networking and learning opportunities for students and scientists at an early career stage.
- Share ideas and results to better orient future research activities and identify priorities in the lines of actions.
- Find a possible common activity where all the group can interact.
- Promote interaction with end-users (this is a topic with high applicative potential).
- Promote scientific sessions at congresses and publication of special issues.
- Facilitate the interaction for funding applications.
Short-term plans
The first initiative is to have an informal meeting to share ideas, show ongoing research activities and possibly start planning future collaborations.
The kick-off meeting of the Fault2SHA Thematic Lab on Fault Displacement Hazard will be held online, on Wed June 14 2023, at 15-16:30 UTC.
Link to access the meeting will be e-mailed to registered participants only. Send a message to francesca.ferrario (at) uninsubria.it to confirm your attendance.
Become a Fault2SHA member (specifying FDH Lab) if you want to be updated on future initiatives.
