  • 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.

  • Database of sterile deposits and coarse materials poured dry (mine tailings) that originate in the mines and quarries. Contains the National Inventory of Mining Tailings and Structures of Mixed Type with information related to physical and geological characteristics, type of mining, impact on the environment, possibility of exploitation, etc. This information has been obtained through the completion of the National Inventory of Mining Ponds and Minig Tainlings from the IGME from 1983 to 1989. It is a georeferenced factual database managed with SQL Server.

  • Database of sterile deposits from mining washers. It also contains alphanumeric information of the different registers, documentary information (photographs, sketches and situation maps). This information is of national scope and has been generated thanks to the agreement "Update of the National Inventory of Mining Sterile Bodies" signed by the IGME and the General Directorate of Mines (MINER) in 1999. Information contained in the "Inventory" has also been used. in the "National Inventory of Mine Waste Ponds and Mining Tailings" carried out by the IGME between 1983 and 1989. It is a georeferenced documentary database managed with SQL Server, available online at http://info.igme.es/balsas
