From: Characteristics of the stress and barometric seismograms produced by the 2011 Tohoku Earthquake (M9.0) and vertical movements derived from barometric seismograms

Fig. 4

Comparison between the barometric variations derived from the vertical movements observed at the time of the Tohoku Earthquake on March 11, 2011, and the observed barometric variations. The upper portion shows the vertical movements at the TOKI-GPS observation point. In the lower portion, the red line shows the barometric record at the SN-3 observation point, the green line shows the barometric record at the STG200, and the black line shows the barometric variations computed by differentiating the vertical movements observed at TOKI-GPS
