Abstract

Summary

Nowadays seismic methods are commonly used in geological research because they give a clear image of the structure at various depths. The resolution of the seismic image depends on the amount of data. Therefore to maximize the use of recorded seismic data the combination of a few seismic methods is proposed. In this paper, an optimal combination of geophysical methods is suggested to study the near-surface geological problems. A standard reflection seismic imaging is supported by multi-channel analysis of surface waves, first breaks traveltime tomography and Ground Penetrating Radar. All these methods are cost-efficient and easy to perform. Using all recorded wavefield, high-quality images are obtained down to 200 m with small additional processing. The Mesozoic bedrock is clearly visible in the seismic imaging as a very strong reflector. Its depression is probably connected to erosion or structure (syncline). Under this horizon, it is possible to find one or two detachments related to the nearby fault. Moreover, the field work was an opportunity to test in-house modifications to seismic source and GPS based timing device, and both systems worked correctly.
