Seismologists usually describe the change in the amplitude of seismic waves with distance R in terms of a power equation such as A =B/Rn. This equation is often used to analyze experimental results on underground explosions. ...
We consider the movement of free blocks in a rock body undergoing deformation. To identify the principal qualitative phenomena accompanying this process, a simple model is used. A cubic block interacts with neighboring ...
Assuming that the earthquake focus is a rock volume filled with aftershocks, the author considers the concept of the center C of an earthquake and the distance ri from it to any point on the earth's surface. For this purpose ...
Since the 1950's, a large body of information has been collected on the structure and geophysical characteristics of Antarctica. Data from seismic stations both in the interior of the continent and on its coast indicate ...
