Key Terms

Seismic Waves
Waves of energy that travel through the Earth, used to study subsurface structures.

Example: Seismic waves are generated during an earthquake.

Ground Penetrating Radar (GPR)
A geophysical method that uses radar pulses to image the subsurface.

Example: GPR can detect buried objects and geological features.

Electrical Resistivity
A method that measures the resistance of the ground to electrical current.

Example: Used to locate groundwater resources.

Magnetic Surveys
Techniques that measure variations in the Earth's magnetic field.

Example: Magnetic surveys help identify mineral deposits.

Geohazards
Natural hazards that pose risks to life and property, such as earthquakes and landslides.

Example: Geohazards can be assessed using geophysical methods.

Data Interpretation
The process of analyzing geophysical data to draw conclusions.

Example: Data interpretation is crucial for hazard assessment.
