Phylogeny and evolution of ontogeny of the family Oxytomidae Ichikawa, 1958 (Mollusca: Bivalvia)     

O. A. Lutikov  I. E. Temkin  B. N. Shurygin 《Stratigraphy and Geological Correlation》2010,18(4):376-391

We described ontogenies and reconstructed morphogeneses of hinges in some supraspecific taxa of the bivalve family Oxytomidae Ichikawa, 1958 from the Mesozoic of Russia. The phylogeny of the family is reconstructed using evolutionary and cladistic methods. The appearance of the endemic genus Arctotis Bodylevsky, 1960 in the epicontinental seas of Siberia can be explained in terms of gradual transformations of the ligament and byssal apparatus in the Northern Siberian members of Praemeleagrinella Lutikov et Shurygin, 2009 and Praearctotis Lutikov et Shurygin, 2009.  相似文献   

The Gorkha earthquake of April 25, 2015 in Nepal: Tectonic position,aftershock process,and possibilities of forecasting the evolution of seismic situation     

E. A. Rogozhin  A. I. Lutikov  L. E. Sobisevich  To Shen  K. Kh. Kanonidi 《Izvestiya Physics of the Solid Earth》2016,52(4):534-549

The characteristics of the foci for the main shock and strongest aftershocks of the Gorkha earthquake of April 25, 2015 in Nepal are described. The macroseismic data and examples of seismic dislocations are discussed. The progression of the release of seismic energy by the aftershock process is analyzed. The data for the geophysical and seismological precursors of the main shock and the strongest aftershock of May 12, 2015 are presented. These data allowed us to formulate the short-term forecast of this event.  相似文献   

岩石层—大气层—电离层耦合作为震前大气层和电离层短临事件的影响机制

介绍了大气层和电离层震前现象机制的基本观念。简短回顾了观测结果后,我们得出结论：1．流体下层物质（气泡）向上迁移能导致近地表的热水／气体被逐出,并在强度弱化的地区引发地震;2．因此,气泡出现的时间和地点是随机的,但是地震、地球化学异常和前震（地震、SA和超低频电磁异常）是随机关联的;3．大气温度和密度扰动跟随着震前热水／气体释放,导致产生周期为6～60min的大气重力波（AGW）;4．地震引发的大气重力波能导致电离层扰动变化并导致大气层中地平线上无线电波传播、下部电离层低频波扰动和地面超低频辐射衰减的变化。  相似文献   

Great Tohoku earthquake of March 11, 2011: Preliminary seismological analysis     

A. I. Lutikov 《Izvestiya Atmospheric and Oceanic Physics》2011,47(8):971-977

The results of a preliminary analysis of the source zone of the 2011 Tohoku earthquake (M _w = 9.1) near the east coast of Honshu, Japan, are considered. We traced the seismic history of the release of the cumulative scalar seismic moment for the last 110 years and temporal variations in the ordering index for the last 35 years. These parameters are important characteristics of a seismotectonic deformation process. The foreshock activation stage and the initial phase of the aftershock process are studied based on these characteristics.  相似文献   

Strong Earthquakes in 2009–2016 in Central Italy: Tectonic Position,Seismic History,and Aftershock Processes     

A. I. Lutikov  E. A. Rogozhin  G. Yu. Dontsova  M. S. Kuchai 《Izvestiya Physics of the Solid Earth》2018,54(2):233-251

Based on the seismological, geodynamic, and seismotectonic data on the strongest series of earthquakes in 2009–2017 in Central Italy, which were collected by many researchers, mostly Italian, the tectonic position of these events is determined and the seismic history of the region over more than 2000 years of observations of seismic manifestations in Italy is traced in the context of the strong events of the beginning of the 21st century. The aftershock processes of these earthquakes are investigated and, as a result, the possibility of a series of strong aftershocks of the earthquake of October 30, 2016 (M_W = 6.6) is predicted in advance of the actual occurrence of these events on January 18, 2017.  相似文献

Determination of source parameters of strong earthquakes of Kamchatka,the Kurile Islands,and Japan from aftershock sequences     

D. V. Chebrov  A. I. Lutikov 《Izvestiya Physics of the Solid Earth》2007,43(8):669-682

Aftershock sequences of some strong earthquakes of Kamchatka, the Kurile Islands, and Japan are examined. Such source parameters as the length L, along-dip width W, motion on fault D, and stress drop Δσ are determined from the aftershock sequences considered. The values of these parameters were obtained by the formal estimation of linear source parameters (lower bound estimates) and visually (upper bound estimates). The correlation dependences of the obtained parameters on the surface wave (M _S ) and seismic moment (M _W ) magnitudes are calculated.  相似文献

Tectonic position and geological and seismic manifestations of the Gorkha earthquake of April 25, 2015, in Nepal     

E. A. Rogozhin  A. I. Lutikov  Tuo Shen 《Geotectonics》2016,50(5):522-533

The characteristics of sources of the Gorkha earthquake’s mainshock (April 25, 2015, Nepal) and strongest aftershock are given. Macroseismic data and examples of seismic dislocations are provided. The course of seismic energy release during the aftershock process is analyzed. The data on seismological precursors of the mainshock and the strongest aftershock of May 12, 2015, are presented, which allowed the aftershock to be predicted in a short-term interval.  相似文献
