Part of the Geoplanet: Earth and Planetary Sciences book series (GEPS)


This work continues a series of papers published in Izvestiya, Physics of the Solid Earth, in 2003–2006 and devoted to the detection and study of periodic oscillations in the seismic flow and synchronization effects arising before strong earthquakes [Sobolev, 2003, 2004; Sobolev et al., 2005; Sobolev and Lyubushin, 2006; Lyubushin and Sobolev, 2006]. These studies were essentially based on the concepts of the dynamics of nonequilibrium media, including self-organization of the seismic process [Nicolis and Prigogine, 1977; Bak et al., 1989; Sornette and Sammis, 1995; Ott, 2002]. It is assumed that, in a metastable lithosphere immediately before an earthquake, natural periodic oscillations arise and/or oscillations from external sources are selectively amplified, with the microseismic field showing collective behavior.
