Abstract

Fuzzy logic algorithms were created in GC RAS to search anomalies in geophysical records. On the basis of these algorithms the present article gives the notion of internal and external forces of geomagnetic anomaly, provides an analysis of geomagnetic events according to Intermagnet data and describes a new method of study of the dynamics of geomagnetic perturbations migration.
