Fig. 3From: Spatial and temporal influence of rainfall on crustal pore pressure based on seismic velocity monitoringa Example of unfiltered and filtered seismic velocity changes. The colour of the unfiltered velocity change represents the stretching correlation coefficient. b Precipitation, c sea level, and d atmospheric pressure during the study period at the station shown in Fig. 1f. e, f Comparisons of precipitation with changes in sea level and atmospheric pressure, respectively, at the station shown in Fig. 1f. Signals are normalizedBack to article page
