  • 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.

  • Map with the chronolithostratigraphic units of the Valencian Community accompanied by faults and folding structures. It is a unified geological synthesis based on IGME maps of this territory at 1:200.000 and 1:50.000 scale.

  • The Lithological Map of the Iberian Peninsula, Balearic and Canary Islands at a scale of 1:1,000,000 is a map produced by the Geological Survey of Spain (IGME) based on the Geological Map of the Iberian Peninsula, Balearic and Canary Islands published in 1995. The cartographic units represented in it have been established using lithological criteria, with the lithological association defining the limits of each unit. The geological information on the Iberian Peninsula and the Balearic Islands is in UTM projection, zone 30, Postdam datum. The information for the Canary Islands is in UTM projection, zone 28, datum Pico de las Nieves. The map is distributed free of charge in shape format through the IGME website.

  • The continuous and digital Permeability Map of Spain at a scale of 1:200.000000 is based on the continuous Lithostratigraphic Map of Spain at a scale of 1:200.000 and represents the mapped lithostratigraphic levels grouped by similar permeability values. In order to carry it out, firstly, a legend was drawn up in which a degree of permeability was assigned to each mapped lithostratigraphic unit. Five types of permeability were established: Very high, High, Medium, Low and Very low. The different lithologies were associated into 7 large groups (carbonate, detrital, Quaternary detrital, volcanic, metadetritic, igneous and evaporitic), giving rise to a classification by types of aquifers, established according to the formation processes of each permeability. This map clearly shows the hydrogeological domains with a predominance of calcareous and evaporitic, detritic and crystalline aquifers, highlighting the main peninsular and island structural lines that bring the different groundwater bodies defined into contact with each other. This cartography is adapted to the hydrographic network and the shadow model produced by CEDEX, at a scale of 1:200,000, based on the topographic base, at a scale of 1:50,000, of the Army Cartographic Service. The cartographic information is referenced to coordinates in UTM projection, European Datum, zone 30, except for that corresponding to the Canary Islands, which is referenced to zone 28. The map is made up of the Cartographic Units Information Layer (LPIT) and the external table dat table, which assigns to each lithostratigraphic formation (FH) the degree of permeability as well as the colour of representation. The format of the generated information is Shape file.

  • Map delimiting the areas with different types of land movements, representing the most intense and frequent movements. It therefore shows the distribution and extent of the most problematic areas from a practical point of view. Land movements are classified into four main groups: horizontal component movements (landslides and landslides), vertical component movements (subsidence and subsidence, and expansive clays), unstable processes in coastal areas and movements related to mining operations. Areas with significant erosion processes are also included. This map, published in 1987, was drawn up entirely by staff of the Geological Survey of Spain in response to the need for information on geological hazards and risks on a national scale.

  • The Permeability Map of Spain at a scale of 1:1,000,000 is the Hydrogeological Map of Spain at a scale of 1:1,000,000, classified according to permeability. Permeability is represented by colours, while lithostratigraphy or hydrogeology is represented by symbolisation of the materials. It is a synthesis of the permeable hydrogeological formations and aquifers at national level, resulting from the systematic studies carried out by the IGME until 1991 on the hydrogeological characteristics of the territory of Spain, determining the location of the aquifers, evaluating their degree of exploitation, hydrodynamic characteristics, resources and reserves, and the quality and contamination of their waters. The map has been drawn up by the Geological Survey of Spain in compliance with its specific functions. It covers the national territory of the Iberian Peninsula, the Balearic Islands and the Canary Islands. The first edition of the Hydrogeological Map of Spain at a scale of 1:1,000,000 corresponds to 1991. A second edition was produced in 1999, incorporating the Hydrogeological Units of Spain into the hydrogeological map.

  • Map with the chronolithostratigraphic and igneous units of the province of Badajoz grouped together as a support for the mapping of mineral resources in the province. The contacts between the different cartographic units have been classified as "stratigraphic contact" and "intrusive contact". The tectonic structure is expressed by faults.

  • The Hydrogeological Map of Spain at a scale of 1:1,000,000 presents the geological units classified according to their hydrogeological character, based on the surface permeability of the outcrops. The hydrogeology is represented by symbolisation of the materials. It is a synthesis of the permeable hydrogeological formations and aquifers at national level, resulting from the systematic studies carried out by the IGME until 1991 on the hydrogeological characteristics of the territory of Spain, determining the location of the aquifers, evaluating their degree of exploitation, hydrodynamic characteristics, resources and reserves, and the quality and contamination of their waters. The map has been drawn up by the Geological and Mining Institute of Spain in compliance with its specific functions. It covers the national territory of the Iberian Peninsula, the Balearic Islands and the Canary Islands. The first edition of the Hydrogeological Map of Spain at a scale of 1:1,000,000 corresponds to 1991. A second edition was produced in 1999, incorporating the Hydrogeological Units of Spain into the hydrogeological map.

  • The map of the island of La Palma includes volcanic and sedimentary units separated by different types of contacts: undifferentiated between formations, between lava flows of the same formation and intrusive. The different units have been grouped into different categories according to their genesis, structure and arrangement, such as eruptions, edifices or volcanoes. The direction of the flow lava flows is shown by means of the corresponding symbology. Tectonic processes are shown as faults and recent local features as active slumps. Additional information includes mineral deposits and indications, archaeological sites and other volcanic elements of specific representation. The map is accompanied by the chronolithostratigraphic legend and conventional signs.

  • Visualisation service of QAFI, 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.
