摘要：

Specific electromagnetic signals in the ULF range, which were observed in seismoactive regions prior to some strong and moderate earthquakes, are discussed with respect to the earthquake prediction problem. Characteristic features of such "seismogenic" ULF emissions are pointed out and compared with differential peculiarities of the ULF emissions of space origin. A new magnetometer technique for locating ULF emission sources is described. Methods are proposed for ULF data processing to investigate preparation activity within the earthquake source region, and to distinguish seismogenic signals from the background of space pulsations. Possible generation mechanisms of the ULF electromagnetic signals in seismic hazard systems are discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
