Earthquake‐related electromagnetic phenomena have recently been considered a promising candidate for short‐term earthquake prediction. There has accumulated a lot of evidence of precursory signatures in a wide frequency range (DC to VHF), but the ULF geomagnetic change is one of the most promising phenomena. We review our results on seismogenic ULF emissions; and characteristics of those emissions and methodologies to detect abnormal changes in ULF electromagnetic field associated with earthquakes. © 2007 Wiley Periodicals, Inc.
