Fig. 12From: Spatial and temporal influence of rainfall on crustal pore pressure based on seismic velocity monitoringa The correlation map between seismic velocity change and pore pressure. b The map of diffusion parameter for each depth (1, 1.5, 2, 4, 6, and 8Â km). The stations with negative correlations smaller than 0.2 are not included on the map. The colour bar in each panel represents the different range of hydraulic diffusion rateBack to article page
