The Seismic Method measures earth's elastic property by observing propergation of seismic wave sourced by hammer-hitting, weight dropping or explosives. The data are sensed by a series of geophones along a line, and recorded by a digital recorder. A portable PC controls the recording and stores data.
A RAS-24 digital recorder by Seistronix records 24 channels of data at a time. The configuration is flexible and ideal for high-resolution shallow survey for environmental and engineering applications, as well as resource survey to the depth of approximately 50 metres.
The data are processed in-house with Parallel Geoscience's SPW system for reflection and refraction surveys and SurfSeissoftware by Kansas Geological Survey for surface wave analysis.
