   The statement of the problem in the theoretical and experimental way of
   detection of earthquake heralds in different Earth geophysical fields is
   far from solution, therefore using new effective methods of detection of
   short-term heralds of great earth-quakes is a problem of paramount
   importance. The carried out investigations showed that to solve the
   problem of forecasting it is advisable to use method of eigen vectors
   allows to analyze and to use effectively non-dominating energetically
   uncorrelated components of the analyzed signals. It has been got a patent
   of this method - an analyzer of eigen vectors and a signal component
   116242 RU.

   The analysis according to the proposed method of the radon monitoring data
   received at the set of the stations of Kamchatka branch office of RAS
   geophysical service on Petropavlovsk geodynamical proving ground before
   the earthquake with M=6.3 which took place on 30, July of 2010 in
   Avachinsk bay. Showed the efficiency of the developed analyzer for
   exposing heralded anomalies. The developed method is being planned to use
   for processing retrospective data at the first stage, and at the next one
   in the real time conditions in order to raise the estimation efficiency of
   seismic danger in Petropavlovsk-Kamchatsky region. The work was being done
   with support of RFFI grant 11-05-97518, FCP 14B37.21.0668, State Task
   5.2971.2011, FCP 43, SC 74-ОК/11-7.
