The results of statistical analysis of perturbations of geoacoustic emission using the method of superposed epoch. It is shown that 45,8% perturbation of geoacoustic emission arise in the daily range of 2,5 to strong earthquakes.
The results of simulation of characteristics of atmospheric ?- and ?-radiation fields due to radioactive decay of soil radionuclides are represented. Monte-Carlo method was used for simulation. Secondary radiation and cascade nature of radiation interaction with air were taking into account. Features in vertical profiles of ? - and ? - radiation absorbed doses and flux densities in ground atmosphere are discussed in detail.
In this paper, we study the boundary value problem for loaded differential equations of fractional order with the Barrett operator in the main part.
ПРИНЦИП ЭКСТРЕМУМА И ЕДИНСТВЕННОСТЬ РЕШЕНИЯ ЗАДАЧИ ДИРИХЛЕ ДЛЯ УРАВНЕНИЯ ЛАВРЕНТЬЕВА-БИЦАДЗЕ С ДВУМЯ ПАРАЛЛЕЛЬНЫМИ ЛИНИЯМИ ИЗМЕНЕНИЯ ТИПАЗ.В. Кудаева

Описана маломодовая модель в которой реализуются различные известные режимы космических динамо-систем, в частности, различные режимы инверсий. Источником регулярных инверсий в модели служит ее внутренняя динамика. Нарушение этой цикличности, сбои в работе динамо-машины, выход на режим хаотических инверсий вызываются флуктуациями параметров, которые интерпретируются как результат спонтаного когерентного сложения высших мод. Простота модели позволяет легко модифицировать ее для различных небесных тел.
In the simulation of passionarii impulses, we should consider redistribution of passionarii energy between seven ethnic subsystems (passionarii, harmonious people, subpassionarii, organization, science and technology, culture and art, landscape). Each passionary subsystem is characterized by a certain level of the passionary energy, which increases or decreases depending on the subsystems interactions.
The work was a mathematical model that describes the effect of the sliding attachment (stick-slip), taking into account hereditarity. explicit finite-difference scheme for the corresponding. Cauchy problem was constructed. Built on the basis of its waveform and phase trajectories
РАСЧЕТ ПАРАМЕТРОВ СЕЙСМИЧЕСКОГО РЕЖИМА НА ОСНОВЕ ВЕРОЯТНОСТНОЙ МОДЕЛИ КАТАЛОГА ЗЕМЛЕТРЯСЕНИЙ КАМЧАТСКОГО РЕГИОНАV.V. Bogdanov & A.V. Pavlov
Simple formulas were obtained on the basis of a probabilistic interpretation of Kamchatka region earthquake repetition law. Using these formulas the number of seismic events falling within an unrepresentative interval energy class (magnitude) was calculated and the expected time of an earthquake with a magnitude exceeding the maximum registered values for the period of instrumental observations was estimated.
The whistlers pattern recognition algorithm in the spectrogram of VLF-radiation and algorithm of the filtering of pulse signals in the spectrograms are proposed.
The paper shows the new methods of analysis of ionospheric and magnetic data using developed by the authors models of multicomponent constructions (MCM models). During periods of high solar activity ionosphere and geomagnetic data is analyzed according to ground stations
The paper presents the results of investigation of cyclone impact on ionosphere parameters. Ionosphere state was observed by the automatic sounding equipment applying low-orbital navigational spacecrafts in the conditions of low seismicity
Problem of high-energy particles flux origin in clouds is discussed. Conditions in which dark lightning preceding the ordinary one and creating additional ionization, fluxes of fast electrons with MeV energy prior to the earthquake detected among lightning initiating ball-lightning, glow, sprites are considered. All above phenomena appear to be of general nature founded on quantum entanglement of hydrogen bonds protons in water clasters inside clouds.

To investigate high frequency geoacoustic emission, a receiving system based on a compound vector receiver was installed in Kamchatka. It allows the authors to determine the direction of sound wave arrival. In the result of the data analysis for the period from August 2008 to January 2016, it was determined that geoacoustic emission directivity anomalies occur during the majority of the earthquakes with Ks >9.0 in the South of Kamchatka.

Statistical estimates of the effect in the electric field of the surface layer of the atmosphere parameters, such as time of the beginning, time of a maximum, its intensity and duration, were obtained. It was shown experimentally that the diurnal variation maximum of atmospheric electric field intensity is associated with air temperature height distribution. Power spectra of time variations of electric field intensity in the near ground atmosphere and of the horizontal component of geomagnetic...
Spectral analysis of electromagnetic noise radiation in the VLF range at three fixed frequencies for the period from 1997 to 2015 have been carried out. Periodograms with diurnal components associated with the periods of the Earth rotation relatively the Sun and the stars have been obtained. It has been shown that the Sun х-radiation and the galaxy х-radiation affect daily variations of VLF radiation.
The data obtained by the World Wide Lightning Location Network (WWLLN) in the territory of Zabaykal’e are compared with the data received by the equipment for observations of Earth’s natural pulse electromagnetic field installed in Buryatia. Diurnal and seasonal dependence of lightning strokes observed in Zabaikal’e territory were obtained. It was shown that the maxima in diurnal variation registered by the instrumentation in Buryatiya coincide with the main world lightning sources.
