The efficiency of a seismic station is assessed firstly by considering the threshold response in terms of bodywave magnitude ( m pv min ) at given distances and under given noise conditions and, secondly, by considering the possibility of recording P, S and L waves whose periods and amplitudes differ from those of the first arrival. The study covers the interaction between signal spectra, noise spectra and the frequency response of available instruments. An international programme to improve knowledge of the relevant parameters is suggested.
