50 YEARS OF CONTINUOUS THREE-DIMENSIONAL RECORDING OF THE BROADBAND SPECTRUM OF SEISMIC WAVES IN SLOVENIA
Abstract
Since 1969, the three-dimensional instrumental broadband recording of seismic ground vibrations has been continuously operating at the Astronomical Geophysical Observatory (AGO) on Golovec in Ljubljana. In that year, two types of measurements began, using top quality analogue seismographs for the time, which, together, non-linearly covered the broadband range of ground vibrations and could record both nearby earthquakes and teleseisms. This article describes the background, the measuring equipment and the operating procedures of this equipment.
