Results of ULF magnetic field measurements near the epicenters of the Spitak (Ms = 6.9) and Loma Prieta (Ms = 7.1) earthquakes: Comparative analysis
O. A. Molchanov,Yu. A. Kopytenko,P. M. Voronov,E. A. Kopytenko,T. G. Matiashvili,Antony C. Fraser-Smith,A. Bernardi +6 more
TL;DR: The characteristics of the magnetic field emissions measured at two magnetic observatories in the Republic of Georgia prior to and after the 6.9 earthquake near Spitak, Armenia, on December 7, 1988, are compared with the apparently similar emissions associated with the 7.1 earthquake that occurred near Loma Prieta, California, on October 17, 1989.

TL;DR: In this article, the spectral density ratio between the horizontal and vertical components (polarization) exhibits an anomalous behavior two weeks before the earthquake, which suggests that this anomalous change might be a possible signal associated with the earthquake preparation phase.
