The extraregional seismotectonic method for prognosis estimation of se
ismic potential (M(max)) is presented. Information on the recent struc
ture and state of the Earth's crust is used as the initial data for pe
rforming the seismotectonic analysis. The Earth's crust typification i
s performed applying computer procedures of cluster analysis for the t
erritory of the major part of Europe of the adjacent aquatories and Ce
ntral Asia Application of the method results in an essential improveme
nt of the prediction of the site and strength of expected earthquakes
within seismically active territories and also makes possible the esti
mation of the seismic potential of weakly active regions from the same
methodological standpoint.
