Geofizikát

Geofizikát is an interdisciplinary field that studies the physical properties of the Earth and its subsurface by applying principles of physics to geoscience data. It brings together geology, physics, mathematics, and computer science to interpret signals generated by natural and man-made processes within the Earth.

Researchers in geofizikát integrate field measurements, laboratory experiments, and numerical modeling to infer parameters such as density, elasticity, conductivity, and temperature, which govern seismic waves, gravity, magnetism, and electromagnetic signals. This holistic approach aims to reveal subsurface structures, material properties, and dynamic processes that are not directly observable.

Common methods include seismic reflection and refraction, gravity and magnetic surveys, electrical resistivity tomography, magnetotellurics, borehole logging, and ground-penetrating radar. Data collection is often complemented by remote sensing, geological mapping, and laboratory measurements on rock samples to constrain models.

Data analysis in geofizikát often relies on forward modeling and inverse problems to convert surface observables into subsurface models; stochastic methods, Bayesian inference, and machine learning are increasingly used to handle uncertainties and to integrate diverse data types.

Applications span natural resource exploration, groundwater assessment, geothermal energy, geotechnical engineering, environmental monitoring, and natural hazard assessment. The field informs decision-making in mining and oil and gas, informs water resource management, and supports infrastructure planning and risk mitigation.

Geofizikát is typically pursued within geophysics, geology, or earth science programs at universities, with training in physics, mathematics, computer science, and field geology. Fieldwork may involve deploying sensor arrays, calibrating instruments, and long-term data collection, often in collaboration with industry, government agencies, or research institutes.
