Overview

This monograph contains experimental and theoretical considerations on synchronization and triggering in laboratory fracture experiments and in earthquake processes. Non-linear dynamics and the physics of rotational motions reveal such ordering in geophysical processes and observed time series. Presented experiments with electromagnetic and mechanical forcing show synchronization of the slip instabilities observed as acoustic burst emissions. New observational results, based on a net of broadband seismic stations, indicate the hidden periodicities and multiple coherence effects in the low frequency microseismic oscillations observed tens of hours before the earthquakes. These results are supported by observational evidence on synchronization between shear oscillations and rotation motions in microseismic fields before earthquakes occur.
