Examples of time-series data from station 1 TYE (location in Fig. 3) around the time of the 2011 Tohoku-Oki earthquake. a Hourly values of atmospheric pressure and precipitation. b Hourly values of strain showing the original (upper) and corrected (lower) data. For data correction, tidal changes and the effects of atmospheric loading were removed by using the BAYTAP-G program (Tamura et al. 1991). c Enlargement of the records shown in (b) around the time of the mainshock. The sampling rate was 20 Hz. The linear trend has been removed. d The same data after application of a low-pass filter of 250 s
