Relatively homogeneous distribution of ambient seismic noise sources. a Azimuthal dependence of the stacked monthly CCFs presented in Fig. 5 on the normalized amplitudes. For BB station pairs in the 1–10-s period band, SP station pairs in the 0.2–5-s period band, and integrated BB and SP station pairs in the 1–3-s period band. b Two examples of the stacked monthly CCFs versus interstation distance for the BB station pairs corresponding with JNU and TKD
