ABSTRACT: The
high level of noise is a special feature of the geomagnetic field on the
territory of Slovenia. The tension of the Adriatic tectonic microplate, on
which Slovenia entirely lies, was recognized as one of its sources. The
interior of the Earth is also the source of geomagnetic jerks. They are
impulses in the secular variation calculated on the basis of monthly or annual
mean values of variation of the geomagnetic field. The paper presents an
analysis of accelerations in a local magnetic field calculated on the bases of
daily mean values of the magnetic field measured at PIA geomagnetic Observatory
(Piran, Slovenia) in 2020. These accelerations indicate geomagnetic impulses at
the regional level over days or weeks. Then these results are compared with the
registered seismic activity in the West Balkans.
