The Italian DISS database (Basili et al., 2008; DISS Working Group, 2010) was analysed in particular, as it is the basis for the European project SHARE and in view of an eventual implementation of QAFI in a European active faults database.
An important difference from DISS and other databases is that QAFI was designed to be populated by the free collaboration of Earth science researchers rather than by a team specifically formed for the task.
The above mentioned changes and additions have led to the most recent version of the database which has also a new acronym: QAFI. QAFI v.2.0 was completed in December 2011 and includes 262 records.
QAFI v.2.0 is released in two different basic formats: static, as an Access .mde file; and online through IGME web page, as an ESRI[R] shapefile.
QAFI v.2.0 contains 262 records corresponding to 241 single faults or fault-segments; 21 records correspond to faults embracing a number of segments (multi-segment faults) (Fig.
In QAFI depth is input either as a minimum and maximum value.
Maximum depth of the fault in QAFI v.2.0 corresponds ideally to the maximum depth where fragile deformation can still go on in the fault plane and so earthquakes can be produced -i.e., the depth of the seismogenic crust.
Most of the records that do not show information in this field (23%) are either Portuguese faults -because this information was not available from the SHARE database at the time they were included in QAFI v.2.0, or offshore faults.
However, in QAFI v.2.0 14 % of the records still lack this information; half of them (48%) belonging to marine regions as the Alboran Sea or the Atlantic OceThe distribution of slip rate (Fig.
Even though QAFI v.2.0 represents to date the most complete database of Iberian Quaternary faults, it is clear that many still remain to be compiled.
QAFI v.2.0 is to date the most informative source for fault-related seismic hazard in Iberia; even though the database still needs to be completely reviewed for conformity to standards.
