Figure 11From: The characteristics of geoelectric fields at Kakioka, Kanoya, and Memambetsu inferred from voltage measurements during 2000 to 2011Comparison of Z yx at KAK with and without trend correction. The trends at τ2 = 10−4 (red diamonds) and τ2 = 10−5 (orange circles) are removed from E y, while no trend correction is applied to E y (blue squares).Back to article page
