In 2003–2004, long-term seismic noise observations were launched on Shikotan Island (Lesser Kuril Range) based on the “Shikotan” dormant regional seismic station. The geological and geophysical data on the registration area are reported. Information about the equipment and its technical specifications is given. The precursors to the strongest local earthquakesthat occurred in the Shikotan Island region in January 2005–March 2007 are identified. 相似文献

A combined stochastic correlation model for the pole’s motion of a deformable Earth is constructed using the data of the International Earth Rotation Service and dynamical Euler equations taking into account tidal deformations. The deterministic component of the model describes the main regular dynamical effects, while its stochastic component describes irregular effects obeying statistical laws. Linear differential (requiring solutions of ordinary differential equations), and finite (assuming integrated characteristics) correlation models are constructed for both Gaussian and non-Gaussian random parameters. The stochastic oscillations and trend of the Earth’s proper angular velocity are analyzed, as well as nonlinear stochastic oscillations and the trend of the pole. This approach can be considered quite novel. 相似文献

The paper considers the impact of ship oscillations on the accuracy of radiation flux measurements in the absence of a gyroplatform
and a gimbal suspension. As an example, we discuss the simultaneous determinations of the radiation fluxes and careen during
the 20th mission of the R/V Akademik Joffe. A sampling rate of 10 s was found to be sufficient to neglect the careen when estimating the hourly sums of the short-wave
solar radiation at sun heights exceeding 10°. At smaller sun heights, the careen is able to effect the estimates of the solar
radiation within 20%. Due to the harmonic nature of such oscillations, these errors tend to become low against the instrumental
accuracy if one deals with the hourly and daily means of the short-wave solar radiation fluxes during sufficiently long observations.
In addition, a significant effect occurs at rather low sun and a sea roughness of Beaufort number 4 or higher. A rough sea
is usually associated with the diminishing of the clear sky area and the higher repeatability of the cloudiness conditions,
which reduces the effect of rolling upon the measurement accuracy. 相似文献

In geoarchaeological studies, there is an issue with distinguishing between natural and anthropogenic signals in pedological paleoarchives. With the pedostratigraphy of the Upper Paleolithic site of Kostenki 14, this issue is reflected by problems with the determination of features of pedogenic and pyrogenic processes. This issue was addressed by means of a thorough analysis of the magnetic properties of paleosols accompanied by micromorphological observations. Most of the humic samples were shown to be a result of pedogenesis, but two samples (a Paleolithic hearth sample and a sample from paleosol IIc) had features of intensely burnt material. The difference in the typical intensity of large-scale (natural or human-induced) and local-scale anthropogenic fire allowed for suggesting that the magnetic properties of the burnt sample were the result of an anthropogenically controlled fire event, that is, a hearth. This study shows that the magnetic properties of paleosols can be used to differentiate anthropogenic activity, in particular—burning, from pedogenic processes. This indicator is especially helpful in finding disturbed combustion features when the hearth structure is lost. This methodology used to demonstrate the local human-induced pyrogenic effect at the Upper Paleolithic site can contribute to the discussion of the niche construction effect of human activities in the Pleistocene. 相似文献

Hardware and software are developed for the first base seismic station in the modernized seismic subsystem for tsunami warning
on Kamchatka. The station is formed as a seismic array. The structure of the equipment and its communication systems are described.
The station is introduced into experimental operation. The first results of recording of a local strong earthquake at points
of the Petropavlovsk station are discussed. 相似文献

Decomposition of samples with a poorly soluble complex matrix for the analysis of the trace-element composition with high-resolution inductively-coupled plasma mass spectrometry was designed and tested. Analytical and method problems of the selection and preparation of samples are described and their solutions are proposed. The correctness of sample preparation was verified using analysis of standard rock samples. 相似文献

This paper presents results from a monitoring study in high frequency seismic noise in Kamchatka during 1992–2006 and reports their use for predicting large regional earthquakes (M ≥ 6.0) in an epicentral distance range Δ within 400 km. The prediction is based on an original method using earth tides as the standard external excitation to study patterns of seismic emission. The method as used at present is described in detail. Guidelines are delineated for future refinement of the prediction method. 相似文献

This article provides some astronomical background for a systematic study of the lunar regolith. The Moon, like other atmosphere-less bodies, is the subject to all kinds of cosmic radiation, which are imprinted in the lunar surface. Therefore, the study of the lunar regolith for signs of cosmic radiation can assist to trace the history of changes in these emissions over time. Mostly changes in the solar wind and galactic cosmic rays are very interesting at time intervals from a few tens of millions of years to several billion years. The paper develops the idea of paleoregolith, the possible location of which can be seen on the slopes of some craters (Euler, Bessel) in images obtained by camera of LRO spacecraft (LROC). Because of the complexities of placing a spacecraft on the slopes of craters, some other possible locations of paleoregolith are offered to consideration. To study the recent history of the evolution of the Moon and the inner planets (up to 200 million years) the stored information in impact and volcanic melts, which are widely represented in the LROC images, should be considered. 相似文献

The specialized station of high-frequency seismic noise registration “Nachiki” is described arranged on Kamchatka in 1987.
The instrument-methodical aspects of registration are considered, as well as history of observations development. New principal
experimental results of surveys are represented. The results of use of high-frequency seismic noises are summarized to reveal
strong earthquake precursors in the online mode in 1996–2008. 相似文献
