STRUCTURE OF THE UPPER PART OF THE EARTH'S MANTLE FROM OBSERVATIONS OF EARTHQUAKES WITH INTERMEDIATE DEPTHS OF FOCUS
A study of the earth's mantle was conducted on the basis of earthquakes occurring in the Pamir-Hindu Kush epicentral zone. In order to improve the accuracy of the determinations of the geometric coordinates of the foci, five temporary seismic stations were set up in the immediate epicentral zon...
