-
(1984)Seismic signals from large explosions recorded by Soviet seismic stations in the distance range from 100 to 2800 km during 12-14 years are analysed. Periodic variations of travel times and amplitudes of P and S waves ...
-
(2004)The low-frequency mechanical properties of pure and Ca-doped lead orthophosphate, (Pb1–xCax)3(PO4)2, have been studied using simultaneous dynamical mechanical analysis, X-ray diffraction (XRD), and optical video microscopy ...
-
(2003)Two explosive eruptions occurred on 2 January 1996 at Karymsky Volcanic Center (KVC) in Kamchatka, Russia: the first, dacitic, from the central vent of Karymsky volcano, and the second, several hours later, from Karymskoye ...
-
(2001)The paper considers main peculiarities of neotectonic structure in respect to epicentre distribution in the Russian Far East South. For this purpose, epicentre distribution of earthquakes with M≥1.8 and M≥3.3, the averaged ...
-
(1986)Study of focal mechanisms of earthquakes in the Near and Komandorsky Islands indicate that there are several distinct zones of tectonic activity. South of the Near Islands, normal faulting occurs in the trench east of 172°E ...
-
(2000)Gradual restriction of fracturing toward the plane of the future main rupture and its subsequent localization near this plane are qualitatively described by the avalanche unstable-fracturing model of earthquake precursors. ...
-
(2005)The block-lava effusion at Volcán de Colima, México began on November 20, 1998, after 12 months of seismic activity, and ended about 80 days later. Three types of seismic events were observed during the lava effusion. ...
-
(2002)The seismicity of Chukotka forms the central part of a Trans-Bering seismic belt that extends from the Koryak highlands through the Seward Peninsula to central Alaska. The seismicity of the Chukotka section has been recorded ...
-
(1997)Newly compiled Russian and U.S. seismological data support an independent Bering block in motion relative to the North American plate. This motion is likely to be driven by the westward extrusion of southwestern Alaska, ...
-
(2003)A statistical analysis of the relative distance and time delay separating pairs of earthquakes is performed, to determine how a seismicity system evolves dynamically following a stress perturbation (earthquake). We analyse ...
-
(2004)This paper presents a further development of mathematical model, an asymptotic theory and an appropriate numerical algorithm to study the vector VLF point source field propagation problem within the non-uniform Earth–ionosphere ...
-
(1989)The objective of combined seismometric and tectonophysical investigations is to construct the dynamic models of the lithosphere from the study of its deformation elements and to research stress and deformation relationships ...
-
(1989)The patterns of electric current passage through rocks are still not completely understood. Also by no means fully understood, are the geoelectric phenomena produced by the passage of seismic waves. Earlier studies devoted ...
-
(1989)The study of seismoacoustic noise has revealed many scientific and practical applications of this phenomenon. The noise data can be used in prediction of rock-bursts in mines, of earthquakes and other dynamic processes in ...
-
(2004)We summarize seismogenic structures in four regions of active convergence, each at a different stage of the collision process, with particular emphases on unusual, deep-seated seismogenic zones that were recently discovered. ...
-
(2000)This study of seismogeodynamics and seismicity in North Eurasia was based on the idea of a structural, dynamic, and energy unity of the geophysical medium and of seismogeodynamic processes operating in it. This unity is ...
-
(2002)We present a semi-analytical, semi-numerical method to simulate wave propagation in piecewise heterogeneous media that the Earth presents. Wave propagation in such media will highlight the reflections/transmissions at ...
-
(1989)Seismogravitational oscillations are movements of the earth in which inertial and gravitational accelerations of similar magnitude are generated on its surface. These include the lowest-frequency characteristic oscillations ...
