Reflection Seismic Survey
Main Purpose: To map the subsurface layers by recording the reflections of seismic waves.
How It Works: A seismic wave is generated at the surface, and as it travels through the Earth, it is reflected by different layers of rock. The time it takes for these waves to return to the surface is recorded and analyzed to create detailed images of the subsurface structures.
Main Uses:
1.Oil and Gas Exploration: Identifying potential reservoirs and faults that may contain hydrocarbons.
2.Mineral Exploration: Locating mineral deposits, such as gold, coal, and metals, by mapping the geological structure.
3.Geotechnical Engineering: Assessing the soil conditions for construction projects or infrastructure development.
4.Seismic Hazard Assessment: Identifying faults and predicting potential seismic hazards in earthquake-prone areas.
Refraction Seismic Survey
Main Purpose: To measure the properties and depths of subsurface layers based on seismic wave refraction.
How It Works: In refraction surveys, seismic waves travel through different subsurface layers and are refracted (bent) at boundaries between materials with different velocities. The time it takes for the waves to return to the surface is measured to calculate the velocity of seismic waves in each layer and estimate the layer's depth.
Main Uses:
1. Site Investigations: Mapping the depth and nature of bedrock and unconsolidated materials for civil engineering projects like dam construction or roadbuilding.
2. Groundwater Studies: Identifying the location of aquifers or groundwater resources by studying the subsurface layers.
3. Environmental Surveys: Assessing the depth and distribution of contaminants or pollutants in the ground.
Surface Wave Seismic Survey
Main Purpose: To analyze the surface waves and estimate the properties of shallow subsurface layers.
How It Works: Surface waves (such as Rayleigh or Love waves) travel along the Earth's surface and are sensitive to near-surface materials. By measuring the velocity of these waves, researchers can infer the stiffness and composition of shallow subsurface materials.
Main Uses:
1.Seismic Site Characterization: Evaluating the stiffness and shear-wave velocity of near-surface materials, which is important for earthquake engineering.
2.Foundation Design: Providing information for the design of foundations for buildings and infrastructure by understanding the near-surface soil conditions.
3.Environmental Monitoring: Studying the impact of surface contamination or remediation activities on shallow ground layers.
