International Union of Geodesy and Geophysics

The International Union of Geodesy and Geophysics (IUGG) is a global organization that promotes the study of Earth's physical properties, processes, and systems—such as how our planet's shape, gravity, magnetic fields, and internal structure work. It unites scientists from around the world to share research, develop standards, and address Earth's dynamic behaviors, including earthquakes, climate change, and oceanography. By fostering international collaboration, the IUGG advances our understanding of Earth’s processes, helping societies better prepare for natural hazards and manage the planet’s resources sustainably.
