Coincident GPR and ultra-shallow seismic imaging in the Arkansas River Valley, Great Bend, Kansas
The primary objective of the work-in-progress reported here is to compare near-surface imaging results using ultra-shallow (upper 3 m) seismic-reflection techniques and ground-penetrating radar (GPR) at an alluvial site near Great Bend, Kansas. Although various seismic and GPR surveys have been used for near-surface imaging, little i s known about how the two techniques might work in concert fo...
متن کاملGPR and seismic imaging in a gypsum quarry
Ž . A combination of ground penetrating radar GPR and seismic imaging has been performed in a gypsum quarry in western Europe. The objective was to localize main cracks and damaged areas inside some of the pillars, which presented indications of having reached stress limits. The GPR imaging was designed from classical profiles with GPR processes and a customized, PC-based image-processing softw...
متن کاملNear-surface VSP surveys using the seismic cone penetrometer
We have found that high-quality vertical seismic profile (VSP) data can be collected for near-surface applications using the seismic cone penetrometer. Conemounted accelerometers are used as the VSP receivers, and a sledgehammer against the cone truck baseplate is used as a source. This technique eliminates the need to drill a borehole, thereby reducing the cost of the survey, and results in a ...
متن کاملCover Sheet Near-surface Interface Detection for Coal Mining Applications Using Bispectral Features and Gpr
The use of ground penetrating radar (GPR) for detecting the presence of near-surface interfaces is a scenario of special interest to the underground coal mining industry. The problem is difficult to solve in practice because the radar echo from the near-surface interface is often dominated by unwanted components such as antenna crosstalk and ringing, ground-bounce effects, clutter, and severe a...
متن کاملNear - Source Imaging of Seismic Rupture
The nature of failure in earthquakes is one of the most fundamental questions in geophysics. We approach this problem using near-source seismic recordings of strongground motion to image the rupture process of earthquakes. We apply the technique to three well-recorded earthquakes in California and interpret the results in terms of earthquake rupture dynamics. To calculate theoretical seismogram...
