Seismic Electric Signals and 1/f "noise" in natural time (P.A. Varotsos, N.V. Sarlis, E.S. Skordas)
Comment from Prof. Varotsos: It might be worthwhile to be added that actually after 4 days, i.e., on February 14, 2008, a major earthquake occurred which -according to USGS http://neic.usgs.gov/neis/qed/ had a magnitude 6.9 and
epicenter at 36.64N 21.83E. The predicted region in our arXiv paper was
36.0-38.6N, 20.0-22.5E, and hence the earthquake -which is the largest
earthquake in Greece during the last twenty years- occurred inside the
predicted area.
