Оптические характеристики термосферы и мезосферы
Шевцов Б. М., Пережогин А. Н., Середкин И. Н.
Используя лидарные сигналы на длинах волн 561 и 532 нм в диапазоне высот 30-400 км, путем решения обратной задачи восстанавливаем коэффициенты рассеяния света, соответствующие этим длинам волн, что позволяет сравнить оптические характеристики термосферы, мезосферы и верхней стратосферы и ...
Аппроксимация законов распределения времён ожидания форшоков на основе дробной модели деформационной активности
Шереметьева О.В,, Шевцов Б.М.
В статье рассматриваются два алгоритма построения последовательностей форшоков, связанных с главным событием заданной энергии, на основе ранее разработанной авторами статистической модели деформационного процесса. Для исследования используется каталог землетрясений КФ ЕГС РАН (01.01.1962 − 31. ...

Observation of the State of the Near-surface Lithosphere Layer based on the Analysis of the Dynamics of the Geoacoustic Emission Signal Characteristics
Senkevich Y. I., Mishchenko M. A., Solodchuk A. A.
The main cause for the occurrence of seismic phenomena is associated with tectonic movements of the earth’s crust. Such displacements generate elastic waves propagating in the lithosphere. These waves are called geoacoustic emission. ...
Mathematical Model of the Formation of Geoacoustic Emission Zones in the Elastic Approximation of the Medium
Gapeev M.I., Solodchuk A.A
Geoacoustic emission is the emission of elastic waves by rocks as a result of their dynamic restructuring. Geoacoustic emission zones are areas of the Earth’s crust surface with relative deformations from to . ...
Mathematical Model of High-Frequency Geoacoustic Emission
Solodchuk A.A., Gapeev M.I., Sergienko D.F., Parovik R.I.
Geoacoustic emission is an indicator of the stress-strain state of the lithosphere, so it plays an important role in the development of methods for predicting strong earthquakes in seismically active regions such as Kamchatka. ...

Fractional Criticality Theory and Its Application in Seismology
B.M. Shevtsov, O.V. Sheremetieva
To understand how the temporal non-locality («memory») properties of a process affect its critical regimes, the power-law compound and time-fractional Poisson process is presented as a universal hereditary model of criticality. ...
Hereditary Mathematical Model of the Dynamics of Radon Accumulation in the Accumulation Chamber
D.A. Tverdyi, E.O. Makarov, R.I.Parovik
Mathematical modeling is used to study the hereditary mechanism of the accumulation of radioactive radon gas in a chamber with gas-discharge counters at several observation points in Kamchatka. ...
mplicit Finite-Difference Scheme for a Duffing Oscillator with a Derivative of Variable Fractional Order of the Riemann-Liouville Type
V.A. Kim, R.I.Parovik, Z.R. Rakhmonov
The article considers an implicit finite-difference scheme for the Duffing equation with a derivative of a fractional variable order of the Riemann–Liouville type. The issues of stability and convergence of an implicit finite-difference scheme are considered. ...

On the Impact of Geomagnetically Induced Currents on the Energy System of the Altai Republic and Siberia
Uchaykin E. O., Gvozdarev A. Yu., Kudryavtsev N. G., Yadagaev E. G.
An assessment of power-transformer overload in the power system of the Altai Republic and the Sayano-Shushenskaya HPS resulting from geomagnetically induced currents (GICs) has been performed. ...

Problems of processing of raw data from magnetic observatories: will modern mathematical technologies help?
Khomutov S.Y.
Various aspects of the measurements and processing of raw magnetic data obtained at observatories are considered. It is noteworthy that the processing can be executed through simple mathematical methods and algorithms at almost all stages. ...
