Fault2SHA Central Apennines database and structuring active fault data for seismic hazard assessment

Area of Science:

• Geosciences
• Seismology
• Tectonics

Background:

• Detailed data on active faults are essential for accurate seismic hazard modeling.
• Existing datasets may lack standardized organization, hindering integration into advanced models.
• The central Apennines region is tectonically active, requiring robust hazard assessments.

Purpose of the Study:

• To present a structured database of field data for active faults in the central Apennines.
• To facilitate the incorporation of fault data into seismic hazard and risk models.
• To provide recommendations for reporting fault data to improve uncertainty analyses.

Main Methods:

• Compilation of field data including fault traces, locations, activity, and certainty levels.
• Inclusion of slip-rate, slip-vector, and surface geometry data.
• Organization of data for easy understanding and integration into modeling frameworks.

Main Results:

• A comprehensive database of active fault data for the central Apennines.
• Recommendations for reporting data certainty and slip-rate calculations.
• Data and maps available in multiple formats (kmz, kml, geopackage, spreadsheets, txt).

Conclusions:

• The presented database structure aids in organizing essential fault data for hazard modeling.
• Standardized reporting of data certainty and collection parameters enhances uncertainty analysis.
• Accessible data formats promote the use of this information in seismic risk assessments.
