- Аннотация: The traditional approach of GPS investigations is determining trends which are connected with the motion of tectonic plates. At the same time, a global GPS network provides the possibility of investigating statistical properties of high-frequency earth surface tremor in different parts of the world. Based on the results of coherence and correlation analysis of noise components of daily 3-component GPS time series, representing measurements of earth surface displacements at 1097 stations, we have found that during 2010-2011 there was a significant increase in the average level of noise coherence or correlation with dominant periods 7-9 days of surface tremor in 9 regions of the earth, and in some of these regions the average level of coherence or correlation is still high and does not return to the previous level. The increase of the average level of coherence and correlation could be detected on the graphs purely visually, while the middle time point of the time interval in which the ascending occurred is detected more precisely by a formal method based on the use of the Fisher ratio. Keywords GPS noise, spectral coherence measure, correlation, synchronization, Fisher ratio.
