The INGV seismogenic source model is managed by a relational MapInfo spatial database. Table B1 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 Basil et al. (2009) and visit the DISS web site:

| Field name | Variable | Description |
|---|---|---|
IDSource |
Char(7) | The DISS-ID assigned to the record. |
SourceName |
Char(64) | Seismogenic source name, taken from local geographical names based on the location of the source. |
CompiledBy |
Char(64) | Name(s) of the compilers of the record. |
LatestUpdate |
Date | Date of the last update of the record. |
Preferred |
Logical | Logical value used to indicate if the record complies with predefined requirements. It can be used for generating automated selections or controlling show/hide options of records. |
| Field name | Variable | Description | Units |
|---|---|---|---|
| MinDepth | Decimal(6, 1) | Value of the minimum depth of the source, or depth of the upper edge, from sea level. | kilometer |
| MaxDepth | Decimal(6, 1) | Value of the maximum depth of the source, or depth of the lower edge, from sea level. | kilometer |
| StrikeMin | Smallint | Minimum value of the source direction, between 0 and 2π clockwise from north following the right-hand rule (Aki and Richards 1980). | degree |
| StrikeMax | Smallint | Maxmum value of the source direction, between 0 and 2π clockwise from north following the right-hand rule. | degree |
| DipMin | Smallint | Minimum value of the dip angle between 0 and π/2 from the horizontal. | degree |
| DipMax | Smallint | Maxmum value of the dip angle between 0 and π2 from the horizontal. | degree |
| RakeMin | Smallint | Minimum value of the hanging-wall sense of movement between 0 and 2π measured counterclockwise from the strike direction. | degree |
| RakeMax | Smallint | Maxmum value of the hanging-wall sense of movement between 0 and 2π measured counterclockwise from the strike direction. | degree |
| SlipRateMin | Decimal(5, 2) | Minimum value of slip as a function of time. | mm/year |
| SlipRateMax | Decimal(5, 2) | Maximum value of slip as a function of time. | mm/year |
| MaxMag | Decimal(3, 1) | Maximum value of earthquake magnitude in the moment-magnitude scale (M). | scalar |
