A new elastic model for ground coupling of geophones with spikes

Ground coupling are terms that describe the transfer from seismic ground motion to the motion of a geophone. In previous models, ground coupling was mainly considered as a disk lying on top of a half-space, not considering the fact that in current practice geophones are spiked and are buried for optimal response. In this paper we introduce a new...

A theoretical and experimental approach to the geophone-ground coupling problem based on acoustic reciprocity

Prestack time-time image map

In this paper we present a method for obtaining the pre-stack image map in the horizontal time – vertical time domain. Our approach is based on a data analysis in the double Radon domain, where the spatial complexity of the subsurface leads to a recognizable structure. Conventional velocity analysis is avoided by quantifying the scaling...
