A wave group which is most attractive in the transversal component and is dispersed has been observed on the occasion of the experiment of seismic waves generated by small sized simple explosions using three-component seismometers.
For the purpose to ascertain that this type of wave group is a kind of Love waves, the following investigations were made; i) whether SH waves are produced simultaneously or not, ii) the comparison of the observed dispersion curve to the calculated, iii) generation characteristics of the waves in question, with special respect to the differences of shot depths and of charge amounts, and iv) the coherence of the other surface waves.
Finally, remarks on excitation mechanism of the Love waves by means of the explosions are added.
