SEISMICITY EVOLUTION AND ORDERITY CHANGE IN WHOIE PROCESS OF MAJOR EARTHQUAKE
Gu Haoding;Sun Wenfu The Seismological Bureau of Liaoning Province
Making use of seismic frequency as order parameter, We establish the master equation of order arameter, which repesents reqular evolution of seismicity, by means of adiabatic elimination principle. With resulting solutions of the master epuation, they canexplain various seismicity phenomena and orderity change in whole proceas of major earthquake. It is specially significant for the system's fluctuation to be able to expand by oneself and to become a decisive factor of propeling phase trasition or sudden change at trasition point.
