The data collected from a geophysical survey is analysed to draw meaningful conclusions out of that. Analysing the spectral density and the time-frequency localisation of any signal is important in applications such as oil exploration and seismography.
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]
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
Works completed by engineering geologists include; geologic hazards assessment, geotechnical, material properties, landslide and slope stability, erosion, flooding, dewatering, and seismic investigations, etc. [3] Engineering geology studies are performed by a geologist or engineering geologist that is educated, trained and has obtained ...
Geologists, can be generally identified as a specialist in one or more of the various geoscience disciplines, such as a geophysicist or geochemist. Geologists may concentrate their studies or research in one or more of the following disciplines: Economic geology: the study of ore genesis, and the mechanisms of ore creation, geostatistics.
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

John Tuzo Wilson (October 24, 1908 – April 15, 1993) was a Canadian geophysicist and geologist who achieved worldwide acclaim for his contributions to the theory of plate tectonics. He added the concept of hot spots, a volcanic region hotter than the surrounding mantle (as in the Hawaii hotspot).
These professionals are qualified to perform the role of or interact with engineering geologists. Their primary focus, however, is the use of engineering geology data, as well as engineering skills to: Design advanced exploration programs, environmental management or remediation projects including: Groundwater extraction and sustainability,
