What types of sensors can detect underground structures?

Various types of sensors can be used to detect underground structures, depending on the specific characteristics of the structure and the desired level of detail in the detection. Ground-penetrating radar (GPR) uses electromagnetic pulses to detect variations in subsurface materials, making it ideal for locating buried objects and structures. Seismic sensors can detect changes in ground vibrations caused by underground structures, such as tunnels or pipes. Magnetic sensors are commonly used to locate objects with metal components, while acoustic sensors can detect changes in sound waves from underground structures. Additionally, infrared sensors can detect temperature variations in the ground, which can indicate the presence of buried structures. By combining multiple sensor technologies, researchers and engineers can effectively detect and map underground structures with high accuracy.
