Abstract

An analysis of long-term series of observations of the natural pulsed electromagnetic field of the Earth in a network of 10 registrars, located on the Black Sea to the Caspian Sea within the seismic areas of the North Caucasus region, marked characteristic regional features of the behavior of diurnal and seasonal variations of geophysical fields. Developed a method for detecting anomalies with the offset intensity seasonal background. Do an attempt to analyze the relationship anomalies with the activation of the «hot» seismic regions in Central and Eastern Caucasus.
