What is Geophysics?
Geophysics is the physics of the earth and is therefore a subsidiary science of physics. Geophysicists use physical methods to explore the interior of the solid earth and the atmosphere, to understand the dynamic processes (e.g. earthquakes, volcanic eruptions) and to find natural resources hidden beneath the earth's surface which are needed for daily life. Geophysics is therefore a science in which physical investigation methods are applied to the terrestrial body.
What do geophysicists do?
In contrast to other natural sciences, in which research is carried out in an idealized laboratory environment, the body of investigation of geophysical research is sometimes difficult to access. Measurement expeditions take geophysicists to sometimes inhospitable and remote places. One of the most geophysically significant observations is that of elastic waves excited by earthquakes or artificially produced sources. The measurement of the earth's magnetic field and gravity field as well as electrical measurements allow conclusions to be drawn about the properties of rocks.
How do geophysicists work?
Geophysicists use supercomputers to process the large amounts of data obtained from field measurements to establish complex computer simulations for the data interpretation. For this reason, the training in computer and programming skills is an important part of the course.
