Relationship between temporal changes in Vp and Vs. a–c Show variations in Vp and Vs during the observation period at NU.MIK, N.THNH, and N.MKBH, respectively. The blue lines indicate variation during the low precipitation period; the orange lines show variation during the high precipitation period indicated in Fig. 4. Furthermore, d shows short-term velocity change associated with the rainfall indicated in Fig. 4 for NU.MIK. The circular and triangular marks indicate the beginning and end of the period, respectively
