摘要：

ULF electromagnetic emissions from the Spitak (Armenia) earthquake site have been detected. Observations were carried out at the Dusheti and Vardzia (Georgia) observatories at distances 120-200 km from the epicentre in a frequency range 0.005-1 Hz. It is shown that the emission appears several hours before the main shock and some of the powerful aftershocks and is not connected with geomagnetic pulsations of magnetospheric sources.
