How to fill out seismic refraction lab

How to fill out a seismic refraction lab:

1. Gather the necessary equipment and materials such as a geophone, seismic hammer, cables, and a data acquisition system.
2. Choose a suitable location for conducting the lab, ensuring that the area is free from any potential disturbances or interference.
3. Set up the geophones in a linear array or a desired configuration based on the objectives of the lab.
4. Connect the geophones to the data acquisition system using the appropriate cables and ensure that all connections are secure.
5. Calibrate the equipment by performing a test measurement to ensure accurate data collection.
6. Select the seismic source, which can be a sledgehammer, explosive charges, or a vibrator, depending on the availability and suitability for the lab.
7. Generate seismic waves by striking the ground with the selected seismic source and record the arrival times of the waves at each geophone.
8. Repeat the process multiple times, varying the location and intensity of the source, to collect sufficient data for analysis.
9. Once the data collection is complete, transfer the recorded data from the acquisition system to a computer for further analysis.
10. Process the seismic data using appropriate software, such as seismic refraction interpretation software, to calculate the velocities of the subsurface layers.
11. Analyze the results, interpret the velocity profiles, and draw conclusions about the subsurface geological structure.
12. Prepare a comprehensive report summarizing the lab procedure, data collected, results obtained, and interpretations made.
