INTERNATIONAL UNION OF GEODESY AND GEOPHYSICS UNION GÉODÉSIQUE ET GÉOPHYSIQUE INTERNATIONALE

HISTORIQUE BACKGROUND L'Union Géodésique et Géophysique Internationale (UGGI) The International Union of Geodesy and Geophysics (IUGG) est un organisme international non gouvernemental à but is an international, non-governmental, non-profit non lucratif fondé à Bruxelles le 28 juillet 1919. L'UGGI se organization established in Brussels on 28 July 1919. IUGG consacre à l'étude scientifique de la Terre et à l'utilisation is dedicated to the scientific study of the Earth and the au profit de la société des connaissances acquises grâce à application of knowledge gained by such studies to benefit cette étude. L'UGGI est l'une des trois Unions scientifiques society. IUGG was one of the first three Scientific Unions ayant participé en 1931 à l'Assemblée constitutive du established during the Constitutive Assembly of the Conseil international des recherches, devenu ensuite le International Research Council, the predecessor of the Conseil international des unions scientifiques (CIUS) en International Council of Scientific Unions (ICSU) created in 1996, devenu enfin Conseil international pour la science 1931, known as the International Council for Science since (CIS) en 2018. Le CIS est un forum planétaire des 1996, and as the International Science Council (ISC) since scientifiques, qui leur permet d'échanger des idées et des 2018. ISC provides a global forum for scientists to exchange informations, promeut la science en tant que bien public ideas and information, advances science as a global public universel, et exprime l’expression universelle de la science. good, and presents a global voice of science. IUGG brings L'UGGI fournit son savoir-faire concernant les sciences de to ISC expertise on Earth studies from researchers in its la Terre effectuées par les chercheurs dans ses Associations International Associations and Inter-Association internationales et Commissions inter-associations.

Commission Inter-Unions Inter-Unions Commission Le Programme International du Lithosphère, guidé par le The International Lithosphere Program, guided by the Comité Scientifique du Lithosphère (SCL), fut établi en 1980 Scientific Committee on the Lithosphere (SCL), was comme la Commission Inter-Union sur le Lithosphère (ICL) established in 1980 as the Inter-union Commission on the par le Conseil International des Sciences (CIUS), selon la Lithosphere (ICL) by the International Council for Science demande de l'Union Internationale des Sciences (ICSU), at the request of the International Union of Géologiques (UIGS) et l'Union Géodésique et Géophysique Geological Sciences (IUGS) and the International Union of Internationale (UGGI). Le nom fut changé au Comité Geodesy and Geophysics (IUGG). The name was formally Scientifique sur le Lithosphère en 1999. Selon la Décision changed to the Scientific Committee on the Lithosphere in 8.4 de l'Assemblée Générale de 2005 du CIUS, le CIUS a 1999. According to Decision 8.4 from the 2005 ICSU décidé de terminer son soutien du SCL/ILP et de General Assembly, ICSU decided "to withdraw ICSU recommander un décallage de responsabilité vers l'UGGI et sponsorship from SCL/ILP and to recommend that l'UIGS. Depuis cette décision, l'UGGI et l'UIGS ont ratabli la responsibility would then shift to IUGG and IUGS." Since mission du ILP et ont collaboré pour re-définir l'ILP comme that time, IUGG and IUGS have reaffirmed the ILP mission une entité Inter-Union.

On 4 July 2007, at the XXIVth IUGG General Assembly in Perugia, Italy, the IUGG Council decided to launch the International Association of Cryospheric Sciences (IACS) as the 8th IUGG Association. IACS is now a sister organization to long established Associations such as those for Hydrological Sciences (IAHS), Meteorology and Atmospheric Sciences (IAMAS) and Physical Sciences of the Oceans (IAPSO). The decision by the IUGG Council was mainly reached in recognition of the fact that the study of the Cryosphere has to be seen on equal footing to investigations of other components of the Earth system. With the initiation of IACS, its predecessors, the International Commission for Snow and Ice (ICSI) and the Union Commission on Cryospheric Sciences (UCCS) are superseded.

In April 1862, the “Mitteleuropäische Gradmessung” was initiated by a “preliminary consultation” of representatives of the states of Prussia, Austria and Saxony. It was established at the constituent conference in Berlin, October 1864, as the first international scientific association of significance and expanded to the “Internationale Erdmessung” (Association Géodésique Internationale) in 1886. At the first General Assembly of the IUGG in Rome, May 1922, it became one of the constituent Sections of the Union. It took its present name at the IUGG General Assembly in Stockholm, August 1930.

At the Sixth International Congress of Geography (London, 1895), G. Gerland (Germany) presented E. v. Rebeur-Paschwitz’ ideas on the necessity of an international cooperation in seismology. At the Seventh Congress (Berlin, 1899) a Commission séismologique permanente was created. The first meeting of the Commission was held in Strasbourg in 1901 under the name of Première Conférence Séismologique Internationale. Subsequent conferences were held in Strasbourg (1903) and Berlin (1905). During the 2nd Strasbourg meeting, an international convention had been drafted to form the Association Internationale de Séismologie by signatures of member states. After being signed by 18 states the convention came in power on 1 April 1904. It consisted of a permanent Bureau located in Strasbourg, General Assemblies and a Commission Permanente. The Commission Permanente was formed during the Berlin conference and met in Rome (1906), The Hague (1907), Zermatt (1910), Manchester (1911), and Strasbourg (1922). General Assemblies were held jointly in The Hague, Manchester, and Strasbourg. The Association was dissolved by the Strasbourg General Assembly. At the first IUGG General Assembly (Rome, 1922), seismology became one of the constituent Sections of the Union. It changed its name to International Association of Seismology at the IV IUGG General Assembly (Stockholm, 1930) and took its present name at the IX IUGG General Assembly (Bruxelles, 1951). For a detailed account of the history of the International Association of Seismology and Physics of the Earth’s Interior, see: J. H. Hodgson, Our Association, its Past as a Guide to its Future (Comptes Rendus de l’AISPIT, n15, Première Partie, 12-28, 1967); J.-P. Rothé, Fifty Years of the International Association of Seismology (1901-1951) (BSSA, 71, 905–923, 1981); R. Adams, International Seismology (in International Handbook of Earthquake & Engineering Seismology, ed. by Willie Lee et al., 29-37, 2002); and J. Schweitzer & T.
