Fig. 2From: Spatial variation in coda Q and stressing rate around the Atotsugawa fault zone in a high strain rate zone, central JapanExample of the estimation of coda Q−1. (a) Locations of an epicenter (star) and a station (square). Lines show Quaternary active faults. (b) Velocity waveforms of three components recorded at the station in (a). Hatched parts are time windows shown in (c). (c) Fitting of Eq. (1) (gray lines) to RMS amplitudes (black lines) at the 1.5 Hz frequency band.Back to article page
