При исследовании связи электромагнитных и сейсмотектонических процессов по данным трех разнесенных по широте и долготе обсерваторий обнаружены электромагнитные импульсы в диапазоне частот от 0 до 5 Гц, которые наблюдались за минуты до землетрясения. Проведен детальный морфологический и статистический анализ результатов, рассмотрены их общие и индивидуальные особенности. На конкретных примерах иллюстрируется появление сигналов перед разрушительными землетрясениями в Японии, Китае, Румынии и в ряде других сейсмоактивных регионов. Обсуждаются затронутые в работе проблемы, полученным результатам дается качественное объяснение.

In the study of the relationship between electromagnetic and seismotectonic processes, we analyzed the data of three observatories located at large distances, considering both latitudes and longitudes, and detected electromagnetic impulses in the frequency range from 0 to 5 Hz, which were recorded minutes before earthquakes. Detailed morphological and statistical analysis was carried out, and common and specific features were considered. Se­veral cases are discussed to illustrate the occurrence of electromagnetic precursor signals before the recorded devastating earthquakes in Japan, China, Romania and other seismically active regions. A qualitative explanation is given for the study results.
