The Quaternary Active Faults Database of Iberia

Abstract

The Quaternary Active Faults Database of Iberia (QAFI) is an initiative lead by the Institute of Geology and Mines of Spain (IGME) for building a public repository of scientific data regarding faults having documented activity during the last 2.59 Ma (Quaternary). QAFI also addresses a need to transfer geologic knowledge to practitioners of seismic hazard and risk in Iberia by identifying and characterizing seismogenic fault-sources. QAFI is populated by the information freely provided by more than 40 Earth science researchers, storing to date a total of 262 records. In this article we describe the development and evolution of the database, as well as its internal architecture. Additionally, a first global analysis of the data is provided with a special focus on length and slip-rate fault parameters. Finally, the database completeness and the internal consistency of the data are discussed. Even though QAFI v.2.0 is the most current resource for calculating fault-related seismic hazard in Iberia, the database is still incomplete and requires further reviewInstituto Geológico y Minero de España, EspañaDepartamento de Geodinámica, Universidad Complutense de Madrid, EspañaInstituto de Hidráulica Ambiental, Universidad de Cantabria, EspañaDepartament de Geodinàmica i Geofísica, Universidad de Barcelona, EspañaDepartamento de Geologia, Universidade de Lisboa, PortugalInstituto Dom Luiz, Universidade de Lisboa, PortugalÁrea de Geología, Universidad Rey Juan Carlos, EspañaDepartamento de Geología y Geoquímica, Universidad Autónoma de Madrid, EspañaInstituto Superior Técnico, Portuga
