Earthquakes, EQs, are among the natural phenomena that bring, along with floods, hurricanes, etc., a lot of damage annually, although in the whole world less than hydrometeorological phenomena, simply because they are rarer. EQs refer to the type of natural phenomena for which the connection with the ANK34 scales is not directly obvious, although here, as elsewhere, large events are much rarer than small ones, the degree of their heterogeneity is not the same, depending on external conditions, for example, on the place of the event. Below we will show that this is a consequence of the first ANK34 scale. This situation can be traced using the methods of similarity theory and dimensions. The vast majority, more than 90%, of strong EQs occur in certain areas confined to the boundaries of lithospheric plates. Convection in the mantle is non-uniform in space (and time over millions of years), entraining the plates, generates stresses at their boundaries. These stresses are relieved during the EQs by the formation of ruptures in the fragile earth's crust. At the turn of the 1940s, the law of repeatability of EQs depending on their strength, called the Gutenberg-Richter law (Law G-R) was empirically established.
