Abstract:The electric and magnetic variations observed during the earthquake of March 11, 2011 that occurred in the Pacific close to the northeastern coast of Honshu Island in Japan are analyzed. The variations in the electric voltage were measured at the decommissioned submarine telecommunication cable laid on the bed of the Sea of Japan. The neighboring observatories recorded the anomalous geomagnetic variations during the studied time interval; the sources and spatial location of these anomalies are studied. The seismic signals were identified from the seismograms recorded by the broadband seismometer STS-2 at the nearest seismic station.
