Characteristics of the seismicity in depth ranges 0–33 and 34–70 km before ten large and great (M
w
= 7.0−9.0) earthquakes of 2000–2008 in the Sumatra region are studied, as are those in the seismic gap zones where no large
earthquakes have occurred since at least 1935. Ring seismicity structures are revealed in both depth ranges. It is shown that
the epicenters of the main seismic events lie, as a rule, close to regions of overlap or in close proximity to “shallow” and
“deep” rings. Correlation dependences of ring sizes and threshold earthquakes magnitudes on energy of the main seismic event
in the ring seismicity regions are obtained. Identification of ring structures in the seismic gap zones (in the regions of
Central and South Sumatra) suggests active processes of large earthquake preparation proceed in the region. The probable magnitudes
of imminent seismic events are estimated from the data on the seismicity ring sizes. 相似文献

Peculiarities of formation and seasonal dynamics of hydrological structure of the Sheksna River Deep of the Rybinsk Reservoir
are considered. The contribution of various genetic water types, including run-offs of the town of Cherepovets, to the formation
of its water masses is established on the grounds of model calculations. It is shown, that the hydrological structure effects
the distribution of hydrobionts in sewage disposal areas. The assessment of the contribution of Cherepovets run-offs to the
change of total water salinity of the deep is given. 相似文献

Presented are the first results of the development of long-range forecast of forest fire risk on the territory of the Russian Far East. Used are the main concepts presented in the papers of G.R. Bregman and B.M. Ginzburg. Forest fire risk parameters in Khabarovsk territory, Jewish autonomous region, and Amur region for the previous years are reconstructed using the heat-balance methods. Carried out is the first stage of the research based on the synoptic statistical method: the typical fields are singled out of meteorological variables in the troposphere and lower stratosphere in the midlatitudes of the Northern Hemisphere from the Azores to the Aleutian Islands. Presented is the automated system developed by the authors and separating these meteorological fields significant for the forecast of forest fire conditions on the vast territory. 相似文献

The Mesozoic-Cenozoic rhythmic continental sedimentary rocks are analyzed for every particular period and epoch from the Triassic
to the Pliocene. The maximal distribution areas of rhythmic deposits are within the latitudinal zone of 20°-40°. Investigation
of rhythmic Mesozoic-Cenozoic carbonate-containing deposits of Europe and North America enables us to attribute rhythmicity
to climate change owing to insolation and eustatic variations of oceanosphere’s level, on the one hand, and to compare duration
values of the rhythmic unit and rhythmic sequence with cycles of orbital precession, ecliptic plane inclination, and the eccentricity
of the Earth’s orbit, on the other hand. 相似文献

The variations in the structural, textural, mineralogical, and geochemical (isotope) features of Lower to Middle Jurassic siliciclastic sediments along the Chanty-Argun River in Mountainous Chechnya and Georgia are discussed. This profile transects areas with various types of deformed sediments, from the northern comparatively weakly deformed and altered zone, to the southern zone of intense deformation and cleavage. Southward along the profile, these alterations are accompanied by the evolution of clay mineral assemblages, as well as polytypic modifications of micas and their crystallinity index. Increasing intensity of rock alteration and cleavage leads to a change of the K–Ar system, which results in a substantially rejuvenated isotope age of the sediments with a simultaneous increase of their stratigraphic age. 相似文献

The results of the search for Apollo, Amor, and Aten asteroids with the orbits close to those of meteoroids of the δ-Cancrids meteor complex (code DCA), which consists of the northern (code NCC) and southern (code SCC) branches, are presented. The search for small bodies in close orbits was performed on the basis of a multifactorial method of combining several criteria: Drummond orbital similarity criterion, Kholshevnikov metric, and parameters of the dynamic evolution of the orbits using two catalogs of meteor orbits (Japan Meteor Society, SonatoCo, and CAMS Meteoroid Orbit Database v2.0, CAMS) obtained from television observations. Asteroids in close orbits with the meteoroid orbits of the northern NCC and southern SCC branches of the δ-Cancrids are identified only in the Apollo group. The following asteroids are common for the NCC and SCC branches: 2015 PU228, 2014 YQ34, 2017 YO4 (according to the CAMS orbit catalog); Hephaistos 1978 SB, 2003 RW11, 2006 BF56, 2011 SR12, 2014 RS17, 2001 YB5 (SonatoCo catalog). The asteroid 85182 (1991 AQ) is identified only with the northern NCC branch but in two catalogs of meteor orbits. 相似文献
