What are the Scopes of geophysics


Scopes of geophysics Geophysics plays a vital role in meeting the needs of society, such as mitigating natural disasters, protecting the environment as well as finding mineral resources.

Geophysics can be used in many fields such as Natural hazard studies,Resource exploration,Engineering,Environmental application. Natural hazard studies Geophysics studies earthquake. It understand past earthquakes and their impact on society. It Monitor seismic activity. It aslo monitor volcanic activity, Landslides/Mudslides/Rockfalls. Resource exploration Mineral exploration is vital in many countries to increase the income of their people, and their economy relies upon discovering minerals. The minerals excavated are iron, copper, gold, silver, molybdenum, zinc, coal, uranium, sulfide, tin, chromite, potash, etc. geophysical methods are playing an important role in mineral investigation, groundwater investigation and hydrocarbon exploration.

Engineering Geophysical methods provide accurate data about the structure of the subsurface valuable information in the field of engineering. We gather non-destructive measurement data by means of airborne geophysics, along the earth’s surface as well as in or from tunnels and boreholes. It uses in Geophysical subsoil investigation to determine the layer model and the homogeneous areas.Ground surveys and monitoring in areas prone to landslides, geological hazards and karst areas.Geological exploration of tunnel routes.Seismic exploration for tunnel driving.Borehole tomography for detailed exploration of the subsoil, e.g. in the foundation engineering of large structures.

Environmental application Geophysics is used to assess groundwater pollution and in monitoring changes in water quality and groundwater.

Geophysics can aid the investigation of pollution of the groundwater resource and of actual and potential pathways in the subsurface.
