Seismic Refraction Time Calculation

Introduction to Seismic Refraction Time Calculation

The seismic refraction method is widely used in geophysics to determine the properties of the Earth's subsurface, such as the depth to bedrock or the propagation velocity of seismic waves. This formula calculates the travel time (t) of a seismic wave using the average velocity (v) and the depth (d).

Parameter usage:

• d = Depth to the boundary or interface between subsurface layers
• v = Average seismic wave propagation velocity in the subsurface

Output:

• t = Travel time of the seismic wave

Data validation

The velocity and depth should be positive non-zero numbers, and the velocity must be greater than the depth for meaningful results.

Summary

This formula provides a straightforward calculation for the travel time of a seismic wave in the subsurface, which is crucial for geological investigations and construction projects.
