Variations of geomagnetic response functions in Japan
© I.I. Rokityansky, V.I. Babak, A.V. Tereshyn, 2015
Peculiarities of measurements have been described for response functions (RF), historical review of RF application in Japan has been
given together with general condition of earthquake forecast (EQ). Detailed analysis of vast material of processing obtained under conditions
of strong disturbances has been fulfilled. Anomalies of response functions have been distinguished, which occurred during several years before
catastrophic EQ Tohoku, which might be probably recognized as medium-term precursors of that EQ. Anomaly of electric conductivity has
been revealed under the central part of Boso peninsula (Tokyo suburb) in the area of complicated junction of three lithosphere plates.
Key words: earthquake precursors, electromagnetic response functions, vectors of induction, electric conductivity of lithosphere.
