Interaction of volcanism, seismicity and tectonics as a geodynamic process

   The study of space-time geodynamic patterns within the world's most active
   regions, conducted by the authors in recent years, made it possible to
   justify the wave nature of the phenomenon of migration of seismicity and
   volcanism. The data on migration, obtained by the authors, indicate the
   existence of relationships between speed and energy characteristics of
   seismic and volcanic processes; the slopes of such dependencies are
   ''sensitive'' to geodynamic conditions in the regions under the study, to
   compression and tension. Together with the data on energy of movement of
   tectonic plates, the revealed regularities allow the authors to consider
   interrelated (interacting) seismic, volcanic and tectonic processes as a
   part of a single planetary geodynamic process. These results will allow a
   fundamentally new physical models of block geomedium be constructed to
   explore its wave properties.

   Sciences, Grant 12-III-А-08-164, and Russian Foundation for Basic
   Research, Grant 12-07-31215.
