Figure S2. C(T) calculation for the day of the Tohoku-Oki earthquake.
(a) Snap shot of training (green) and prediction (red) based on the
observed VTEC (black dots) at station 0214 for T = 5:20 UT (vertical
gray line) on March 11, 2011 (DOY70). The time of the mainshock is shown
with vertical black line. The polarities of the VTEC curvature are shown
with broken lines. (b) Calculated C(T) using the 31 stations with the
central station 0214. |
