Applications of Downhole Seismic Logging:

• Earthquake site response modeling
• Foundation design for dynamic (vibratory) loads
• Enhancement and quality control of surface seismic interpretations

Applications of Seismic Reflection:

• Depth to bedrock
• Depth to water table
• Fault location
• Mapping buried stream channels
• Other irregular bedrock topography
