Geophysics

Study physical processes and properties of the Earth using seismic, gravitational, and magnetic measurement techniques.

Field Overview

Geophysics applies the principles, mathematical equations, and diagnostic techniques of physics to explore the invisible subsurface architecture, interior structure, and physical fields of planet Earth. Geophysicists use seismic waves, gravitational fields, magnetic anomalies, and electrical resistivity measurements to image deep underground rock structures non-destructively.

Students master seismic reflection processing, gravity/magnetic surveying, electrical geophysics, borehole geophysics, and geophysical inversion mathematics. Guided by global organizations like the Society of Exploration Geophysicists (SEG) and the Environmental and Engineering Geophysical Society (EEGS), geophysicists locate subsea energy reserves, map earthquake fault zones, and locate groundwater aquifers.

What You Will Learn

  • Seismic Exploration & Processing: Processing 2D/3D seismic wave reflection data to construct subsurface structural imaging profiles.
  • Gravity & Magnetic Surveying: Measuring Earth's local gravitational anomalies and magnetic field variations to identify subsurface ore deposits.
  • Electrical & Electromagnetic Geophysics: Utilizing Electrical Resistivity Tomography (ERT) and Ground Penetrating Radar (GPR) for shallow environmental scans.
  • Seismology & Tectonics: Analyzing earthquake wave propagation (P-waves, S-waves), focal mechanisms, and mantle convection.
  • Geophysical Inversion & Modeling: Applying numerical mathematics to convert physical surface sensor data into 3D subsurface geological models.

Career & Industry Outlook

Subsurface energy exploration, mineral discovery, groundwater locating, geotechnical infrastructure engineering, and earthquake hazard monitoring create strong demand for geophysicists.

Frequently asked questions

Geology relies on direct physical observation of surface rocks, mineral core samples, and field mapping. Geophysics uses physical measurement tools (seismic waves, magnetism, electrical current) to non-destructively image subsurface structures kilometers deep.
GPR is a near-surface geophysical technique that sends high-frequency radar pulses into the ground to detect buried utilities, concrete rebar, archaeological artifacts, and shallow rock features.
P-waves (Primary/Compressional waves) are faster seismic waves that travel through both solids and liquids. S-waves (Secondary/Shear waves) travel slower and can only pass through solid rock materials.
Python, MATLAB, and C/C++ are heavily used by geophysicists for signal processing, seismic wave modeling, and data inversion.
