   "abstract": "Independent knowledge of the physical processes that occur with seismic events can be obtained from observations of electric and magnetic fields generated by these complex processes. During the past few decades, we have seen a remarkable increase in the quality and quantity of electromagnetic (EM) data recorded before and during earthquakes and\u00a0volcanic eruptions. This paper describes the most significant recent data and the implications these data have for different generating mechanisms. We note that, despite several decades of relatively high quality monitoring, clear demonstration of the existence of precursory EM signals has not been achieved, although causal relations between coseismic magnetic field changes and earthquake stress drops are no longer in question. This paper extends discussions of tectonomagnetism and tectonoelectricity, over the various parts of the\u00a0electromagnetic spectrum\u00a0from radio frequencies (RF) to submicrohertz frequencies, that are covered in Johnston (1989, 1997), Park\u00a0et al.\u00a0(1993),\u00a0Park (1996)\u00a0special journal issues (Johnston and Parrot, 1989, 1998;\u00a0Parrot and Johnston, 1993), and books (Hayakawa and Fujinawa, 1994).",
