Note on effect of ripple firing on spectra of quarry shots
Series of controlled quarry shots were recorded at distance of approximately 900 ft to ascertain effect of ripple firing on amplitude and spectra of seismic waves; measurable reduction in amplitude of compressional and shear waves was observed at some frequencies; this effect was not so pronounced for surface waves.
