This electronic supplement documents the minimum set of required parameters to characterize seismogenic sources in seismic hazard assessment.
Detailed comparison of parameters in the two data models that are derived directly from geological observations.
Table S1. Definitions for Istituto Nazionale di Geofisica e Vulcanologia (INGV) seismogenic source model parameter fields.
The INGV seismogenic source model is managed by a relational MapInfo spatial database. Table S1 defines only the parameters in the database that were discussed in the text, except for the geographic coordinates of the mapped features that are stored implicitly in the GIS files. This table is not intended to depict the entire data model or to be exhaustive. For further data model and data content information see Basili et al. (2008) and Basili et al. (2009) and visit the DISS web site:

Table S2. Definitions for United States Geological Survey (USGS) seismogenic source model parameter fields.
The USGS database is a relation Oracle spatial database. Table S2 defines parameters in the database that were discussed previously, except for the geographic coordinates of the mapped features that are stored implicitly in the GIS files. This table is not intended to depict the entire data model or to be exhaustive. The USGS database stores computational values as well as expert judgment values that are the foundation of the source model for each version of the national seismic hazard map. As such, the USGS seismogenic source model can be tested in its entirety for reproducibility and can provide customized input files for use in other applications available at:
