Dissymmetry in the Earth's megarelief within the Western Pacific region

Abstract

High symmetry is typical of the planetary relief structure at the level of the oceanic and continental hemispheres, of Gondwana and Laurasia, of oceans and mid-oceanic ridges. Western Pacific region is characterized with breaks in symmetry at all the levels, all of them being superimposed there. The data suggest that the tectonosphere in the region contains some elements of structure and geodynamics which control most important transformations of the Earth's appearance there.
