A Stratified Double-Difference Dynamic Tomography of 3D Velocity Field for Deep-Buried Large Underground Cavern

Key Points

• Dynamic tomography successfully captures the 3D velocity field of large underground caverns with high precision.
• The analysis shows significant variations in velocity, enabling improved understanding of cavern structures.
• Using a stratified double-difference approach, data is processed to enhance accuracy and resolution in measurements.
• These insights may pave the way for advancements in geophysical studies and underground resource management.
