Determination of the nature of seismic waves using combined systems of surface and borehole observations
Authors:
Abstract
Since 1961, the reflected wave method (RWM) seismic survey has been successfully applied to study the Pechenga structure of the Baltic Shield. In the wave fields registered in this area by the systems of elongated hodographs, along with longitudinal P waves, intensive direct transverse S waves are established. This allows us to expect the registration of reflections of different types: longitudinal, transverse, and exchange. When interpreting the wave field in these conditions, much attention is paid to determining the type of recorded waves. ...
