Abstract
Abstract ––The wavefield structure is studied from explosions within the Mururoa atoll based on seismic records from four stations (BCAO, KAAO, GRFO, BRVK) located at distances 152.1º, 152.4º, 143.6º, 141.7º, respectively. The cross-correlation analysis was used as the main tool of the similarity of explosion seismograms conducted at different times. It has been concluded that changes in correlation similarity in time are reconcilable with the hypothesis of differential rotation of the Earth’s inner core in the period from 1977 to 1991. The evidence of structural anomalies not only in the inner core but also in the outer core has been demonstrated.
