Abstract
The set of parameters of geophysical fields and geodynamic events before the strongest Okhotsk Sea earthquake May 24, 2013 with MW = 8,3 and a focal depth of 630 km in this paper analyzed. In the temporary vicinity of the earthquake (May 19-20), there was a temporary synchronization of geodynamic processes in areas of the Kamchatka Peninsula, separated by hundreds of kilometers. The simultaneous occurrence of anomalies in the behavior of tilts, in the dynamics of flow of subsoil radon, conditional deformations of remote foreshock activation in Avacha Bay, speaks of a single geodynamic process on a regional scale, preceding the earthquake. A possible reason for the observed in-phase geodynamic phenomena may be the “geodeformation wave” that arose at the last stage of the preparation of the Okhotsk Sea earthquake.
