Introduction: Progress of Seismology in Polar Region

Abstract

Several kinds of seismological investigations have been conducted in the polar region, which include the areas of both the Arctic and the Antarctic regions, in various depth ranges from the surface layers to the deep interiors of the Earth. The polar region has an advantage in order to seek inside the physical condition of the Earth as a “window” viewed from high latitudes. In this chapter, historical issues and progress of seismic research and its observations in the polar region are demonstrated during the last halfcentury from the era of the International Geophysical Year (IGY 1957–1958).
