Fig. 7

Simulated tsunami wave height and velocity, and induced electromagnetic field around Chichijima Island (star). The left side shows wave height and seawater flow (depth-integrated velocity) as color images and vectors, respectively. The yellow dots indicate the tsunami fronts. The right side shows tsunami-induced magnetic and electric fields as color images and vectors, respectively. The labels on the left side indicate the phases of magnetic field variations. The large arrows indicate representative induced electric currents (purple vectors) and secondary induced magnetic fields (red arcs)
