Abstract

A forecast of an earthquake should identify the first stages of earthquake development: nucleation and stick-slip. We show that a forecast cannot be achieved by seismic measurements due to their high attenuation, but can be obtained by judicial filtering of electromagnetic radiation. Results show that electromagnetic radiation emitted from fractures (FEMR) during the early stages of an earthquake is less attenuated than seismic measurements due to the high frequencies involved, but could be cluttered by external noise. Based on our previous studies, an analysis of FEMR constructed on a profile of individual pulses can remove part of the clatter.
