Members of the scientific community with active membership in geological associations, such as the IAVCEI (International Association of Volcanology and Chemistry of the Earth's Interior ), GSA (Geological Society of America) and EGU (European Geophysical Society), we  work closely with international scientists from volcanological institutes and observatories all over the world.
