Figure 8From: The characteristics of geoelectric fields at Kakioka, Kanoya, and Memambetsu inferred from voltage measurements during 2000 to 2011Apparent resistivity (left) and phase (right) at Kakioka (top), Kanoya (middle), and Memambetsu (bottom). All of the four impedance tensor components at periods of less than 104 s are shown as Z xx (yellow triangles), Z xy (red circles), Z yx (blue squares), and Z yy (green inverted triangles). KAK, Kakioka; KNY, Kanoya; MMB, Memambetsu.Back to article page
