Geophysics is a field of natural science that uses the principles and techniques of physics to investigate the Earth and its surrounding space environment. It aims to understand the Earth’s physical properties and processes, including its shape, internal structure, gravitational and magnetic fields, as well as dynamic phenomena such as plate tectonics, volcanism, and the formation of rocks(Geophysics | Seismology, Plate Tectonics & Geodynamics | Britannica, 2025).
Applied geophysics plays a vital role in exploring subsurface resources such as groundwater, minerals, oil, and gas. It is also essential for assessing earthquake hazards, supporting engineering projects, and managing environmental risks. Since the Earth’s deep interior cannot be directly observed, geophysicists depend on remote sensing, data analysis, and computational modeling to study the planet’s physical structure and dynamic processes(What Is Geophysics?, n.d.).
This multidisciplinary field integrates principles from geology, physics, and environmental science, playing a crucial role in both advancing Earth science research and supporting practical applications such as resource management and hazard mitigation.
Geophysics is the foundational science that guides decisions in mining, oil & gas, and hazard mitigation. What specific geophysical method (e.g., magnetics, gravity, seismic) do you believe is most critical for unlocking future mineral reserves, and why?
