Synchronization and Triggering - From Fracture to Earthquake Processes


Introduction

Processes of synchronization and interaction play a very special role in different

physical problems concerning the dynamics of the Earth’s interior; they are of

particular importance in the study of seismic phenomena, and their complexity is

strongly affected by the variety of geological structures and inhomogeneities of the

medium that hamper the course of these processes and their intensity. The attempt

to tackle these problems is a great challenge from experimental, observational and

theoretical point of view.






We present in this Monograph the theoretical and experimental results achieved

in the frame of the European Project “Triggering and synchronization of seismic/

acoustic events by weak external forcing as a sign of approaching the critical

point” (INTAS Ref. Nr 05-1000008-7889); in this Project, which was inspired by

Professor Tamaz Chelidze, our aim was to give grounds for better understanding

and interpretation of dynamical interactive processes of physical fields, both found

in the laboratory experiments as well as in field observations. One of the leading

problems – related to synchronization and interaction of different physical fields

in fracture processes concerns triggering and initiation of rupture and displacements

within the Earth interior. From this point of view, the results from laboratory

studies on synchronization and interaction and those found and involved in field

observations, helped to improve the theoretical background. Reversely, some of

the presented new theoretical approaches have served to stimulate laboratory and

field studies.
