Figure F10. Horizontal component spectra from the seafloor, buried, and borehole installations at Ocean Seismic Network (OSN)-1 are compared with the spectra from the buried installation at Hawaii-2 Observatory (H2O) and the Kipapa, Hawaii (KIP) GSN station on Oahu. The sediment resonance peaks in the 0.3-8 Hz band are up to 35 dB louder than background and far exceed the microseism peak at 0.1-0.3 Hz. The fact that the resonant peaks are considerably higher for horizontal components than for the vertical component is consistent with the notion that these are related to S-wave resonances (Scholte modes).
