Striking plate
for "P and/or "S" waves
3D Borehole geophones
Crosshole energiser
Hammer Switch / Starter Geophone Exploration Seismograph Refraction Suvey Method
Determining soil properties Elastic moduli of soil and rock and hence give soil properties and site characterization.
Estimate overburden thickness or depth to bedrock
Mapping geologic strata and anomalous conditions
Solve many engineering problems based on lateral or vertical variation and contrasts. Exploration Seismograph Refraction Suvey Method Advantages
Can cover big areas compared with drilling, however dose not cancel it.
Provides data to depths of 100 m or more
Provides 2D cross-section of P-wave or S-wave velocity for the subsurface
The source of seismic energy can be small as simple as 7-kg sledgehammer
Exploration Seismograph Reflection Suvey Method
Primary application is for determination of depth and thickness of geologic strata
Mapping structural and geologic conditions such as subsurface faults
Recent applications have attempted to use higher frequencies to identify smallertargets such as caves or tunnels.
Advantages about Exploration Seismograph Reflection Suvey Method
Provides a high resolution cross-section of soil/rock along profile line
Depth range as shallow as 10 m to greater than 300 meter .
Both P-waves and S-waves can be measured with the appropriate equipment
