Abstract

Electromagnetic oscillations generated by surface Love waves in the Earth’s crust were detected by the spectral polarization method at the Mondy and Sodankyla observatories, located at distances of 5390 and 8798 km from the epicenter of the strong Sumatra earthquake of December 26, 2004. Detailed analysis of this event is instructive because it indicates that the difficulty in detecting the coseismic magnetic oscillations predicted by theory is only due to the presence of strong noise. Observations of this type are shown to be significant for experimental studies of mechanoelectromagnetic conversions in the crust.
