tance to the singular source. Space-time local anomalies
are superimposed on the background level of the carrier
signal, which is determined by the global processes of
electromagnetic dynamics of shells of the Earth. The
cause of local variations may be associated with elec-
tromagnetic phenomena accompanying the geodynamic
processes in the lithosphere-atmosphere-ionosphere.
Important characteristics of the anomalous phenome-
non are the spatial and temporal scale of variations. The
anomalous behavior of the apparent distance to the gen-
eralized source in the energy methods of calculation
manifested not less than two weeks before the catastro-
phic earthquake. Changes curves were recorded during
the three months. Regular declining of the apparent dis-
tances and decrease field homogeneity, coinciding with
the lull seismic activity time intervals, can be interpreted
as the emergence in these periods, and an additional per-
turbation of the magnetic field. This effect is registered
synchronously at all stations, and has a spatial dimension
not less than the size of the entire structure. In turn ab-
normal manifestations, which are caused by activization
zones 11 March 2011, localized in the vicinity of the
station Kakioka, in the measurements of the remote sta-
tions are manifested weaker.
The main result of the study is the fact that, according
to the measurements of the magnetic field of three ob-
servatories in Japan for 2009-2011, the regular variations
of the apparent distances to the effective singular source,
associated with the rhythm of the geodynamic processes
in the vicinity of the station Kakioka, were recorded.
Most strongly the apparent distance decrease manifested
in connection with the activation of seismicity of the
region, including the catastrophic earthquake on March
11, 2011 with the magnitude M = 9.1.
Singular generalized source diagnoses measure elec-
tromagnetic heterogeneity of lithosphere and the iono-
sphere in the vicinity of the magnetic observatories. The
system of three observatories proved itself as a kind of
magnetic locator electromagnetic phenomena associated
with seismic activity in the vicinity of the observatory
Kakioka.
