| Abstract: | The global seismicity shows a characteristic distance of about 23°. The middle-deep and deep earthquakes in the European and
Asian blocks concentrate on several zones which separate about 23° away from earch other. The shallow strong earthquakes (M
s⩾7) form belts of over 20°, the ends of these belts are near the concentration points of middle-deep and deep earthuakes.
The Circular Pacific island arcs, volcanoes, shallow earthquakes, middle deep and deep earthquakes also show the characteristic
distance of about 23°.
