Surveys Electrical Surveys Magnetic Surveys Georadar Crosshole Tomography Seiscope Microseismic Monitoring Marine Geophysical Surveys and ROV . Seismic Surveys Of all of the geophysical techniques, the seismic technique is actually the most developed and, when it can be used, the one that gives the most amount of information.
Seismic methods can reduce the investigation costs of nearly all engineering projects.
This method can be used to locate conductive zones by analyzing the signals generated by permanent or portable stations. This method may be used to locate permafrost, water-bearing intervals, and the bedrock surface. These surveys can be used in environmental site assessments to detect buried metallic objects as well as hydrocarbon contamination plumes. The vibrations produced by blasts, pile driving, heavy machinery and transport, not only disturb people, but can also cause damage to surrounding structures. Permissible levels of vibration and noise must established and followed in order to safeguard the site and local communities to avoid costly claims.
