Time series of the internal temperature of 8 stations during DOY 90–660. The top panel also includes TJT1-2 during an observation period from April 30 to May 24, 2011. The temperature of TJT1-2 is shifted by + 0.06 °C to meet the background temperature level of TJT1. The Mw 9 mainshock occurrence is indicated by solid vertical lines at DOY 434.2403. Time windows between the dashed lines indicate those shown in the next figure (i.e., Fig. 7)
