Research on the Earth's Interior Conducted by Russia after IGY: The Geotraverse Project and "Intermargins"

Abstract

Fifty years have passed since the International Geophysical Year (IGY) of 1957.58, one of the most important and noble initiatives in the history of science and in the history of humanity in general. IGY became the model for subsequent international scientific initiatives in various fields of solid Earth research, including the Upper Mantle Project (1961.71), the Geodynamic Project (1971.80), the Geotraverse Project (1987.2003), and the "InterMARGINS" Project (2003). The Russian investigations as part of the Geotraverse Project and "InterMARGINS" were aimed at research into the deep structure of the continental margins of East Eurasia, which are characterized by high seismicity, volcanism, and natural cataclysms hazardous to people living there.
