Temperature records and pressure variations during DOY 429–449. a, b, and c denote dynamic pressure vibration, residual pressure, and tidal loading pressure (see texts in Sect. 3.3), respectively, at TJT1 and GJT3. In a, the dynamic pressure vibration amplitudes are calculated as root-mean-square amplitudes in respective 1-h time windows. Times of several distinct pressure spikes are marked by vertical dashed lines which are also attached to the other panels. Centroid-moment-tensor solutions of several aftershocks corresponding to the pressure spikes are attached. No reasonable solution is found corresponding to a pressure spike on DOY 438. The moment magnitude, mechanism, and distance from TJT1 are shown. Those parameters are based on the Global Centroid Moment Tensor catalog (Ekström et al. 2012). Large static pressure steps due to the Mw 9 mainshock in b and c are shifted to see small pressure changes before and after the mainshock in the same frames. d and e denote the estimated water temperature of TJT1 and GJT3, respectively. The onsets of the subevents of TJT1 and corresponding tidal loading levels are plotted by green circles and lines in d and c, respectively
