Abstract:

Enhancement of P waves is obtained by the suppression of microseisms with a combination of vertical linear strain seismograph and vertical inertial seismograph outputs. Significant suppression is observed at sites where the predominant microseisms consist of essentially single-mode Rayleigh waves in contrast to that observed at a site where the microseismic noise is compositionally more complex. A description is given of the vertical linear strain seismograph used in these investigations. Consideration is given to the use of a vertical transverse strain seismograph at sites where the microseismic noise field is complex. Author
