Abstract
The purpose of the work is to establish the correlation between the change of absolute rotation poles of major tectonic plates based on continuous GNSS stations data. The work investigates 2804 continuous GNSS stations located on Pacific, North American, Eurasian, African, Antarctic, Australian and South American plates during 2002-2021. The components of recent horizontal displacements of continuous GNSS stations have been determined and a map of their distribution pattern has been constructed. The absolute rotation pole in ITRF2014/IGS14 reference frame of the studied tectonic plates has been determined. The obtained values are in good agreement with modern plate models. The definition of average annual rotation poles has been developed and thei r analysis has been carried out to research the dynamics of their change in time. It has been established that the change in the average annual rotation poles of the North American, African and South American plates occurs synchronously, while their change is asynchronous to the Pacific plate. Simultaneous changes in the average annual rotation poles of Antarctic and African plates were have also been identified.
期刊介绍:
Acta geodynamica et geomaterialia (AGG) has been published by the Institute of Rock Structures and Mechanics, Czech Academy of Sciences since 2004, formerly known as Acta Montana published from the beginning of sixties till 2003. Approximately 40 articles per year in four issues are published, covering observations related to central Europe and new theoretical developments and interpretations in these disciplines. It is possible to publish occasionally research articles from other regions of the world, only if they present substantial advance in methodological or theoretical development with worldwide impact. The Board of Editors is international in representation.
