International Union of Geodesy and GeophysicsThe International Union of Geodesy and Geophysics (IUGG; French: Union géodésique et géophysique internationale, UGGI) is an international non-governmental organization dedicated to the scientific study of Earth and its space environment using geophysical and geodetic techniques. The IUGG is a member of the International Science Council (ISC), which is composed of international scholarly and scientific institutions and national academies of sciences.International Association of Volcanology and Chemistry of the Earth's InteriorThe International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) is a learned society that focuses on research in volcanology, efforts to mitigate volcanic disasters, and research into closely related disciplines, such as igneous geochemistry and petrology, geochronology, volcanogenic mineral deposits, and the physics of the generation and ascent of magmas in the upper mantle and crust.
Seismic sourceA seismic source is a device that generates controlled seismicenergy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite, or it can use more sophisticated technology, such as a specialized air gun. Seismic sources can provide single pulses or continuous sweeps of energy, generating seismic waves, which travel through a medium such as water or layers of rocks.
Seismic waveA seismic wave is a mechanical wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake), volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy. Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones (in water), or accelerometers.
International Association of Geomagnetism and AeronomyThe International Association of Geomagnetism and Aeronomy (IAGA) is an international scientific association that focuses on the study of terrestrial and planetary magnetism and space physics. IAGA is one of the eight associations of the International Union of Geodesy and Geophysics. It is a non-governmental body funded through the subscriptions paid to IUGG by its member countries.

Outline of geophysicsThe following outline is provided as an overview of and topical guide to geophysics: Geophysics – the physics of the Earth and its environment in space; also the study of the Earth using quantitative physical methods.
Liviu ConstantinescuLiviu Constantinescu (26 November 1914 – 29 November 1997) was a Romanian geophysicist, professor of geophysics, member of the Romanian Academy. He was the cofounder, together with Sabba S. Ștefănescu, of the Romanian school of geophysics. BiographyHe was born in Ighișu Vechi, Transylvania (a village now in Sibiu County), the son of Romulus Constantinescu, a sixth-generation Christian Orthodox cleric.
Vladimir Keilis-BorokVladimir Isaacovich Keilis-Borok (July 31, 1921 – October 19, 2013) was a Russian mathematical geophysicist and seismologist. BiographyKeilis-Borok was born in Moscow, Soviet Union. His father, Isaak Moiseevich Keilis, was a jeweler. His mother, Ksenia Ruvimovna Borok, was from Lithuania. Both were Jewish. In 1948, he received a Ph.D. in mathematical geophysics from the Academy of Sciences in Moscow.
GeophysicsGeophysics () is a physical science concerned with the processes and properties of Earth and its surrounding space environment, studied using quantitative and observational methods. It focuses primarily on Earth’s shape and its gravitational, magnetic, and electromagnetic fields. It also studies internal structure, composition, and dynamics, and their surface expression in tectonics, volcanism, and rock formation.
