Analysis of the influence of tidal strain on seismic velocity changes (dv/v) (IMAGE)
Caption
Figure 2. (A) Daily resolution dv/v after removing the influence of environmental factors. (B) The average spectral ratio results along the array. The location of the fault fracture zone is denoted by red lines. (C) Comparison of the spectra of dv/v at hourly resolution (blue curve) and the tidal strain in the vertical component (brown curve). (D) Comparison of the average dv/v of stations within the fault fracture zone and monthly vertical tidal strain time series. The purple dashed line marks the perigee date. (E) Comparison of diurnal dv/v time series with vertical tidal strain. (F) Comparison of semidiurnal dv/v time series with vertical tidal strain.
