Geology
Geology (from the Ancient Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also refer to the study of the solid features of any terrestrial planet or natural satellite, (such as Mars or the Moon).
Geophysics
Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term geophysics sometimes refers only to the geological applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial relations; and analogous problems associated with the Moon and other planets.
Geology
Measuring nuclear yield depends on multiple parameters - the location and number of instruments, the geology of the area, the location of the seismic station in relation to the test site.

Geophysics
Historically geophysics has been the study of the classical linear equations of physics, Laplace's equation for gravity and magnetics, the wave equation for propagating seismic waves, and the heat equation for thermal problems.

Geology
In collecting the primary geologic data, some personal capacities of the geologist (such as strong physique, perceptive faculties, perseverance, talent for drawing) are generally of much greater importance than in any of the sister sciences, which can rely on the quality of the instruments used in collecting primary data… Hans Cloos (1949) called this way of interrogation [by geologists] "the dialogue with the earth," "das Gespraich mit der Erde."
