International scientific organization

IUGG - International Union of Geodesy and Geophysics

IUGG is an international Organization devoted to the advancement, promotion and dissemination of knowledge on the Earth system, its space environment and the dynamic processes that cause changes, at the same time encouraging the information sharing.

Founded in 1919, IUGG is one of the 32 scientific Unions that are currently part of the 'International Council for Science (ICSU).

Thanks to its associations, committees and services, IUGG organizes international conferences and workshops, carries out research, collects observations, acquires knowledge, coordinates activities, collaborates with other scientific institutions, plays the role of defender, contributes to teaching, works to expand preparation and participation worldwide. The data and knowledge gained are made publicly available for the benefit of society and to provide information on elements useful for the discovery and a responsible use of natural resources, for a sustainable management of the environment, by reducing the impact of natural hazards and for satisfying man’s curiosity on planet Earth and the consequences of human activities on it. IUGG has eight associations:

  • 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)

and six committees:

Union Commission on Climatic and Environmental Changes (CCEC)
Chair: Jiangping Li (China)
Secretary: Tonie van Dam (Luxembourg)

Union Commission on Mathematical Geophysics (CMG)
Chair: Alik Ismail-Zadeh (Germany/Russia)
Secretary: Ilya Zaliapin (USA)

Union Commission on Geophysical Risk and Sustainability (GeoRisk)
Chair: John LaBrecque (USA)
Secretary: Katia Kontar (USA)

Union Commission on Studies of Earth’s Deep Interior (SEDI)
Chair: Christine Thomas (Germany)
Secretary: Michael Bergman (USA)

Union Commission on Data and Information (UCDI)
Chair: Satheesh Shenoi (India)
Vice-Chair: Anatoly Soloviev (Russia)

Union Commission on Planetary Sciences (UCPS)
Chair: Shuanggen Jin (China)
Secretary: Scot Rafkin (USA)


IUGG's Associations and Committees encourage scientific research on Earth sciences, especially on its interdisciplinary aspects. Each Association creates working groups and committees.

In October 2014, for the first time, the Committee for the participation of CNR in the International Union of Geodesy and Geophysics (IUGG), with the financial support of the special CNR Division for 'International Relations', has launched a Call for selecting a young researcher for granting a prize to participate in the XXVI General Assembly of IUGG (Prague, 22 June-2 July 2015). The award was granted to Dr. Flavia Tauro who attended the General Assembly presenting two abstracts. A report on IUGG XXVI General Assembly is available:

The new IUGG Council for the 2016-2019 triennium has been recently created. Prof. Giuliano Panza was appointed Managing Director for Italy. The list of delegates is available at the following link:

In May 2016, the report "Future of the Ocean and its Seas: a non-governmental scientific perspective on seven marine research issues of G7 interest " was published. technology-Ministers-meeting-in-japan    

This report is a summary of the work done by an international group of experts made up by IAPSO (IUGG) and SCOR in response to a press released after the "Meeting of G7 Ministers of Science" (Berlin, 8-9 October 2015).

The report contains recommendations to policy makers on how to address seven of the issues identified in the G7 communiqué: Plastic pollution of the marine environment, Deep-sea mining and its ecosystem impacts, Ocean acidification, De-oxygenation, Ocean warming, Biodiversity loss, ecosystem Marine degradation.

During the ICDRM 2017 - International Conference on Disaster Risk Mitigation, held in Dhaka, Bangladesh on 23-24 September 2017 (, prof. Panza was invited for  a Keynote on "NDSHA: robust and reliable seismic hazard assessment". The paper can be downloaded from:


Berlin, Germany was selected as the venue for the 28th IUGG General Assembly in 2023.
