Аннотация: The paper is devoted to the analysis of the features of the EWH parameter change over the geoid using satellite measurements of the GRACE space system. These local gravitational anomalies are studied depending on the geometrical characteristics of the focal zones of the strongest underwater earthquakes in the period 2003-2016. The statistical processing of satellite observations data using the histogram and maximum entropy methods was performed. Completed interpretation and obtained estimates showing differences and similarities in observational data, due to the peculiarities of the structure of the studied geomedia and the corresponding focal areas. The final result is a statistical description of the space of anomalies of the gravitational field of the Earth as a whole and features of local gravitational anomalies over the focal zones of underwater strong earthquakes in the period from 2003 to 2016. © 2019 The Author(s).
