Discussion paper: Electrostriction and magnetostriction arising under the action of large-scale interplanetary magnetic field inhomogeneities on the Earth

Abstract

[1]  When the interplanetary magnetic field polarity changes, the Earth experiences the influence of the interplanetary field, which gives rise to short bursts of intensity of neutron emission from the Earth. This is likely to be associated with deformation of the Earth's crust that can be caused by electrostriction and magnetostriction arising under the action of large-scale interplanetary magnetic field inhomogeneities on the Earth's magnetosphere. In all probability, no increase in the Earth's seismic activity occurs in this case.
