Fig. 2From: Surface wave group velocity in the Osaka sedimentary basin, Japan, estimated using ambient noise cross-correlation functions(Top) Nine components of the inter-station cross-correlation functions obtained in the frequency range 0.1–0.5 Hz for station pairs a UEMC06–UEMC09 and d UEMC05–UEMC13. The hatched area indicates the time window for plotting the particle motion.
