Basic magnetic properties of rocks under the effects of mechanical stresses
TLDR
In this article, the effects of mechanical stresses on the magnetization of the earth's crust can be classified in two categories: (a) the reversible effect which disappears when the stress is removed; and (b) the irreversible effect which causes an irreversible enhancement or an irreversible demagnetization of remanent magnetization.About:

The seismomagnetic effect
TL;DR: In this article, the authors calculate local variations in the geomagnetic field, which are produced by stress changes in crustal rocks, from the stress patterns and the piezomagnetic properties of the rocks down to the Curie point isotherm.

Earthquake Energy, Earthquake Volume, Aftershock Area, and Strength of the Earth's Crust
TL;DR: In this article, the authors deduced the energy of the largest possible earthquake from the spatial distribution of the stress energy within the earth's crust, which was then combined with the magnitude energy relation due to GUTENBERG and RICHTER, yielding a formulaE=6×102×A1·5.

Effects of Uniaxial Compression on Remanent Magnetization
Mitiyasu Ohnaka,Hajimu Kinoshita +1 more
TL;DR: In this article, the effect of directional stress on the remanent magnetization of magnetite bearing rocks and nickel polycrystallites was investigated and a nearly reversible change in intensity was found when the direction of compression is perpendicular to that of TRM.

Theory of the magnetic susceptibility of stressed rock
TL;DR: In this paper, the authors calculated the stress dependence of magnetic susceptibility of igneous rock from the multidomain theory of magnetic grains, assuming that the magnetic mineral is pure magnetite whose saturation magnetization, magnetocrystalline anisotropy and saturation magnetostriction are known.
