Application of the graphs theory for estimation of interconnections of the earthquakes in the Crimean-Black Sea region

© V.B. Spirtus

Notions of T- and R-connectivity of seismic events have been introduced and on their base formalized criterion of earthquakes neighborhood has been proposed. Methodic problems of discrimination of interconnected events with the help of graphs theory have been considered. A set of test calculations for the earthquakes of the central part of the Crimean-Black Sea region have been conducted. It has been demonstrated that in the matrix of orgraph contiguity all the significant activation periods al of seismic activity occurred in 1984, 1990, 1998 and 2009 are reflected. For the Crimean earthquakes of 1984 and 1998 the chains of interconnected events have been distinguished about two years long, which confirm the migration of low rank events to the site of future strong one.
