Performing periodic scientific observation campaigns (registration in discrete mode) to strengthen the seismic-volcanic monitoring of the Teide volcanic systems, Northeast Dorsal, Northwest Dorsal and North North Dorsal of the island of Tenerife, Cumbre Vieja on the island of La Palma, Island of El Hierro and Timanfaya on the island of Lanzarote, on an annual or monthly basis. These campaigns involve the completion of hundreds of measurement points, sampling of gases, subsequent chemical and isotopic analysis in the laboratory and data processing as well as the generation of reports and results.

The areas of study of the geochemical program in discrete mode in the Canary Islands are shown below:
