Geophysical methods are powerful tools to explore the subsoil for environmental investigations. Some geophysical methods, such as gamma-ray spectrometry and remote sensing, measure surface attributes; others, such as thermal and some electrical methods are limited to detecting relatively shallow features but may help identify features at greater depth. Geophysical techniques work through applying one of several types of force to the ground, to measure the resulting energy with use of geophysical equipment and infer the geology from this. Q1: 30: 30-6: SPAT0058-1: Observing Earth from space (anglais) Christian Barbier. Pré-requis . For example, detection of a fault at a depth of several hundred feet, does not require the precision in the measurements that is required to design a bridge foundation. Finally, Romanova et al.
