The International Union of Geodesy and Geophysics, or IUGG, is a non-governmental organisation dedicated to the scientific study of the Earth using geophysical and geodesic techniques. The IUGG was established in 1919. Some areas within its scope are environmental preservation, reduction of the effects of natural hazards, and mineral resources. The IUGG consists of eight associations and three commissions:

• International Association of Cryospheric Sciences (IACS)

• International Association of Geodesy (IAG)

• International Association of Geomagnetism and Aeronomy (IAGA)

• International Association of Hydrological Sciences (IAHS)

• International Association of Meteorology and Atmospheric Sciences (IAMAS)

• International Association for the Physical Sciences of the Oceans (IAPSO)

• International Association of Seismology and Physics of the Earth's Interior (IASPEI)

• International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI)

• Commission on Geophysical Risk and Sustainability (GeoRisk)

• Commission on Mathematical Geophysics (CMG)

• Committee on the Study of Earth's Deep Interior (SEDI)
