In the 20th century, geophysical methods were developed for remote exploration of the solid Earth and the ocean, and geophysics played an essential role in the development of the theory of plate tectonics. Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards and environmental protection. [4]
Geophysics can be described as all of the following: An academic discipline – branch of knowledge that is taught and researched at the college or university level. . Disciplines are defined (in part), and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties to which their practitioners
Near-surface geophysics is the use of geophysical methods to investigate small-scale features in the shallow (tens of meters) subsurface. It is closely related to applied geophysics or exploration geophysics. Methods used include seismic refraction and reflection, gravity, magnetic, electric, and electromagnetic methods.
In 1898, a Geophysical Institute was founded at the University of Göttingen, and Emil Wiechert became the world's first Chair of Geophysics. [3] An international framework for geophysics was provided by the founding of the International Union of Geodesy and Geophysics in 1919.
Cecil H. Green (British-born American, 1900–2003) – exploration geophysics geophysical entrepreneur and philanthropist; Maurice Ewing Medal (SEG) Harsh Gupta (Indian, 1942– ) – methodology for discriminating normal earthquakes from reservoir-induced ones, study on the genesis of stable continental region earthquakes; Padma Shri , Shanti ...
Studying dynamo models has utility in the field of geophysics as doing so can identify how various mechanisms form magnetic fields like those produced by astrophysical bodies like Earth and how they cause magnetic fields to exhibit certain features, such as pole reversals. The equations used in numerical models of dynamo are highly complex.
In 1994 he presented research at a geophysics conference stating that the slip-sliding geologic plates that cover the Earth might once have moved thousands of times faster than they do today. [2] In 1997, U.S. News & World Report described him as "the world's pre-eminent expert in the design of computer models for geophysical convection". [3]
