The Group of Volcanology of Barcelona (GVB) is part of Geosciences Barcelona, CSIC (former Institute of Earth Sciences, ICTJA-CSIC, Barcelona). The GVB was created in 1990 and since then it has concentrated on the study of pre-eruptive and eruptive processes, mainly working in the Canary Islands and La Garrotxa Volcanic Field, but also in many other places around the World (Central Andes, Deception Island, Costa Rica, El Salvador, Mexico, Azores, Cape Verde, Iceland,, etc). The Group of Volcanology is a worldwide-recognised leader on the study of caldera-forming processes and hazard assessment and risk management in active volcanic regions. In Spain it has pioneered the application of numerical and experimental modelling to the study of geological processes and the application of experimental petrology to the study of volcanic processes. The GVB participates and co-ordinates several national and European research projects and is member of the Catalan thematic network on natural risks. The GVB is also member of the Associated Unit CSIC-UPC “TECNOTERRA”, dedicated to the technological development of remote sensors and information management applied to Earth sciences, the Associated Unit CSIC-University of Huelva “Experimental Petrology”, dedicated to the application of Experimental Petrology to the study of magmatic and volcanic processes, and the Associated Unit CSIC-IGN “Active Volcanism” dedicated to the study volcanic unrest. The GVB was also recognised as a Research Group of the Generalitat de Catalunya (2005SGR01061) and is currently part of the Research Group GRC 2017 SGR 1022. The GVB participates in a European initiative to create a network of research groups specialised on modelling and management of volcanic processes, capable of offering a scientific and technological response to the increasing social demand on assessment and forecasting of volcanic hazards. The GVB is scientific advisor of the “Espai Crater” museum project, promoted by the Olot city council, Girona. A relevant result of the group’s activity is the creation of the Laboratory of Simulation of Geological Processes (SIMGEO), from a cooperation agreement between the ICTJA-CSIC and the University of Barcelona signed in December 1995. Among other aspects, this laboratory, aims to promote the application of experimental and theoretical models to the study of geological processes and especially of those which pose a risk to people and the environment.
