STRUCTURAL FEATURES OF THE EARTH INNER CORE ON THE BASE OF LATE CODA AFTER THE MYANMAR EARTHQUAKE ON 28 MARCH 2025
Abstract
The paper presents the results of express analysis of the late coda of the Myanmar earthquake by seismic interferometry method. Anomalies corresponding to waves I1*, I2*, c*, ScS*, are observed in the calculated correlograms based on data from 880 world stations. It is shown that the travel time features of the I2* correspond to anisotropy with a fast axis in the direction of the Earth rotation axis. On the correlograms of the stations for the Alaska region, the I2* wave is weakly expressed, which is probably related to attenuation in the inner core.
