The Society of Exploration Geophysicists of Japan (SEGJ) was established in May 1948 with the objectives to promote the science and technology of geophysical exploration as well as to encourage mutual communication among the members.

SEGJ was initially composed of 416 individual members and 18 corporate members. Dr. Kumiji Iida was appointed as the first president. The first issue of the journal” Butsuri-Tanko (Geophysical Exploration)” was published just a month after the establishment. The office of the Society was situated in the Geological Survey of Japan (GSJ) in Kawasaki at first.

Activating international cooperation, SEGJ currently has association agreement with the Society of Exploration Geophysicists (SEG), the European Association of Geoscientists & Engineers (EAGE), the Australian SEG (ASEG), the Korean SEG (KSEG), the Environmental and Engineering Geophysical Society (EEGS), Vietnam Association of Geophysicists (VAG), the Society of Petroleum Geophysicists China (SPG), and the Indonesian Association of Geophysicists (HAGI).

KSEG (Korean Society of Earth & Exploration Geophysicists) is a non-profit organization established in 2007. It covers a wide range of geophysical activities from pure geophysical studies to exploration or engineering geophysics. It publishes the quarterly journal “ Geophysics and Geophysical Exploration”. It also organizes local Conferences in spring and fall and provides continuing education courses.

The ASEG is a non-profit company founded in 1970. 

Its aims to:

• To promote the science of geophysics, and specifically exploration geophysics, throughout Australia.
• To foster fellowship and co-operation between geophysicists.
• To encourage closer understanding and co-operation with other earth scientists.
• To assist in design and teaching of courses in geophysics and to sponsor student sections where appropriate.
