A database of faults showing geological evidence of activity during the Quaternary period in Iberia (last 2.6 million years according to the official limit set by IQS in 2009). The Quaternary Active Fault Database of Iberia (QAFI) is a project under constant revision and updating as a consequence of the advancing studies and knowledge on the structures capable of generating earthquakes in Iberia. QAFI could never be considered complete or definitive, due to the scientific nature of the data that contains in it as well as for the modus operandi followed in its construction: the altruist cooperation of a large number of Earth science researchers. The database (mdb. and shp. format) is hosted and maintained by the Geological Survey of Spain (IGME) and is accessible to the research and technical community and to society in general.

QAFI is a database of faults with geological evidence of proven activity during the Quaternary period (the last 2.6 million years according to the limit officially established by the SQS in 2009) of the Iberian Peninsula. It is a project in constant revision and updating as a result of the progress of studies and knowledge about the structures capable of generating earthquakes in Iberia, and can never be considered complete or definitive, both because of the scientific nature of the data contained in it, and because of the modus operandi used in its construction: the altruistic collaboration of numerous researchers in Earth Sciences. QAFI, both in Access format and geospatially represented, is hosted and maintained by the Geological Survey of Spain (IGME), and is accessible to the entire scientific and technical community and society in general.
