Fig. 2From: Temporal change in seismic velocity associated with an offshore MW 5.9 Off-Mie earthquake in the Nankai subduction zone from ambient noise cross-correlationReference cross-correlations between station pairs within the five DONET1 nodes. Each node is labeled with the station pair and the propagation direction in positive time. The red lines represent velocities of 0.9Â km/s (outer pair) and 1.5Â km/s (inner pair). a KMA. b KMB. c KMC. d KMD. e KMEBack to article page
