Рассматривается один из возможных вариантов решения проблемы мониторинга начала процесса подготовки землетрясения (ППЗ), основанный на совместном анализе сейсмоакустических и сейсмических сигналов. В целях проведения экспериментов для контроля начала ППЗ построена сеть станций, в которых для получения сейсмической и сейсмоакустической информации из глубинных пластов Земли в качестве канала связи использовались стволы законсервированных нефтяных скважин (1500...5000 м). Установлено, что при фильтрации сейсмических сигналов при применении традиционных технологий теряются информативные признаки, которые возникают в начале ППЗ. Также установлено, что по оценкам дисперсии помехи и взаимнокорреляционной функции между полезным сейсмоакустическим сигналом и ее помехой надежно регистрируется начало ППЗ. Показано, что в течение некоторого времени по тем же характеристикам сейсмических сигналов имеется возможность повторно регистрировать продолжение ППЗ. На основе указанных информативных признаков о начале ППЗ предложена гибридная интеллектуальная система, с помощью которой на основе комбинации сигналов, полученных от сейсмостанций, формируется информация, позволяющая выявить зоны очага ожидаемого землетрясения. Было установлено, что при фильтрации сейсмических сигналов в традиционных сейсмостанциях теряются информативные признаки, которые возникают в период начала ППЗ.

A possible solution to the problem of monitoring the onset of an earthquake preparation process (EPP) is considered by combining the analysis of seismic-acoustic and seismic signals. In order to conduct experiments to monitor the onset of the earthquake preparation process, a network of stations was built in which shafts of suspended oil wells (1500—5000 m) were used as inverted antennas as a communication channel to obtain seismic and seismic-acoustic information from deep strata of the earth. It is found that when filtering seismic signals using traditional technologies, informative attributes that occur at the onset of the earthquake preparation process are lost. It is also found that the onset of the EPP is reliably recorded based on estimates of the noise variance and the cross-correlation function between the useful seismic-acoustic signal and its noise. It is also established that over a period of time, it is possible to repeatedly record continuations of the EPP based on the same characteristics of seismic signals. Based on the specified informative attributes about the beginning of the EPP, a hybrid intelligent system is proposed, where, using combinations of stations that respond to seismic processes, information is generated that allows seismologists to use them as a tool to identify the zones of the focus of the expected earthquake. The importance of the study is that the results obtained have been experimentally confirmed over a long period of time. It was found that informative attributes that emerge at the beginning of the earth-quake preparation process are lost during the filtering of seismic signals by traditional seismic stations.
