Аннотация: The study is devoted to a detailed analysis of observational data from the GRACE space system to refine the parameters of the focal zone of the 2010 catastrophic earthquake with the magnitude MW = 8.8 which occurred in the subduction zone near the Chilean coast. A technique was developed for con-structing maps of the distribution oПоказать полностьюf the EWH parameter (equivalent water height above the geoid contour) and interpreting their anomalies relative to the source area. It is shown that there is a negative correlation between the value of the geodynamic parameter H (the distance from the hypocenter to the position of the Earth-Moon barycenter) for this strong earthquake with МW = 8.8 and the parameter EWH. Within the framework of the comparative analysis, digital maps of changes in the EWH parameter were also constructed for the studied focal areas of the Chilean earthquakes of 2014 and 2015. © 2021 Copyright for this paper by its authors.
