On the topological similarity of the functionals from the statistics of magnetic field measurements before the earthquake on November 3, 2022, in the Gura Teghii, Romania region

Abstract

. The article investigates the properties of small-scale probability density fluctuations for measurements of X , Y and Z -components of the Earth's magnetic field before the earthquake that took place in November 2022 in the southern European region. A comparison is made of the properties of the statistical functional corresponding to the measurements of the magnetic field for three spatially separated magnetovariational stations located at different geographical azimuths with respect to the point of the epicenter of the indicated event. It is shown that for all stations there is a significant topological similarity of the dependences corresponding to the specified functional, considered as a function of time.
