Frequency Modulation of 0S2-C

Authors: Herbert Weidner

Precision measurements of the 0S2 quintet after the 2004-12-26 earthquake show that the middle spectral line near 309.3 µHz is frequency modulated. The strongest modulation frequencies are phase-locked and depend on the geographic location. By proper choice of the integration length the center frequency can be determined with high precision.
