Fig. 9

Comparison and cross-correlations between precipitation and ground water level (GWL), and those between precipitation and seismic velocity. The GWL station of this example is shown in Fig. 1f and the seismic station closest to the GWL station is used for comparison. a Relationship between unfiltered precipitation and GWL. b Relationship between band-pass filtered precipitation and GWL. c Relationship between band-pass filtered precipitation and GWL with precipitation shifted earlier by 5 days. d The relationship between band-pass filtered precipitation and seismic velocity change (normalized) with precipitation shifted earlier by 9 days
