On the Possible Relationship of a Set of Statistically Revealed Quasi-Linear Local Trends of Variations in the Magnetic Field Parameters Prior to Earthquakes in Seismically Active Zones of the Black Sea, Caucasus, and Western Asia

The article examines the properties of a statistical functional constructed from a set of measurements of the H -component of magnetic field measurements. A set of quasilinear objects with very similar parameters has been identified. Based on the hypothesis of the correspondence of these structures...

Summary:The article examines the properties of a statistical functional constructed from a set of measurements of the H -component of magnetic field measurements. A set of quasilinear objects with very similar parameters has been identified. Based on the hypothesis of the correspondence of these structures to seismic processes, authors estimate the characteristic time intervals for the phases of increase and decrease in the level of compression of lithospheric plates in probable preparation zones for impending earthquakes. It is shown that the statistical approach in geophysical problems can be used to assess seismic hazard in a given region in near real time.
