Spain & Portugal - Quaternary Active Faults Database of Iberia - IGME

QAFI database is a project periodically revised and updated as a consequence of Earth Science progress in earthquake prone structures in Iberia. Nevertheless, earthquakes can occur in areas where no active faults were described before either because they were not studied yet or simply because they do not outcrop at the surface. Hence, QAFI data cannot be considered complete or definitive, just updated on the base of available scientific literature.

QAFI database cannot substitute in any way detailed studies for the identification or characterization of seismogenic sources for specific sites, particularly for the design of critical or strategic infrastructure, or for civil protection plans or land management of specific territories. In these cases QAFI main utility is to serve as a platform for guiding further in-depth studies. For fault-specific studies QAFI users are strongly encourage to consult the original sources of information and if necessary contact the main authors or compilers of the data.

Neither the authors of the design, nor the compilers and the Spanish Geological Survey (IGME) or the Laboratório Nacional de Energia e Geologia (LNEG, Portugal) are responsible in any case, neither directly nor indirectly, of the consequences that could be derived from the use of the Quaternary Active Fault Data Base of Iberia (QAFI), both in what respects to the data itself as well as to the cartography of the fault traces. IGME and LNEG are not responsible of the extended information that compilers have associated to particular records.
