On the method of assessment of seismotectonic potential

B. Assinovskaya

Abstract: 

In the scope of this work we have investigated the interrelation of seismicity with geological features and rock mechanical properties mainly on the example of the eastern part of the Baltic Shield. It has been found that earthquake occurrence depends on the rock lithology, its age and the geological evolution of the region. The empirical relationship between energy strength and maximum magnitude are offered. It was revealed that occurrence of the largest earthquakes of the region is connected with undeformed granitized blocks of the crust or granitoid batholithes that have been associated with compression processes. It is known that the typical Archean granite-greenstone highly fractured crust shows a layered formation with variable deformational properties and reduced efficient brittleness. The maps of energy strength, seismic potential and maximum magnitude of the north part of the Kola Peninsula were compiled.
