Abstract The gravitational stresses caused by the density inhomogeneity of the Earth's crust in the Central Kuriles area are calculated. The general trend of the spatial variation of the stress field and its local perturbations due to the structural and density differentiation of the Earth’s crust were revealed. It is concluded that there are areas...

In recent years, the satellite altimeter technology allows to enhance the marine investigation in any area. Up to now, many scientific studies have attempted to improve the accuracy and resolution of altimeter-derived gravity anomalies and have produced a gravity grid with interval of 1' × 1' for most the oceans all over the world. However, this gr...

Present-day stress filed in the Hoang Sa archipelago and adjacent areas is determined through the earthquake’s focal mechanism parameters that have been recorded during a time period of more than 100 years. The geometric parameters of the faults (such as the location, strike and dip angles as well as depth, length…) are determined by satellite-deri...

The modern gravimetry methods are capable of measuring gravity with an accuracy of up to 10–10 of the normal value, which is commensurate with the accuracy of the up-to-date methods of displacement measurements by satellite geodesy. Significant changes, e.g., in the coseismic displacements of the Earth’s surface are recorded in the zones of large e...

Based on the combined analysis of the seismologic and other geophysical data (the gravity and magnetic fields and the acoustic basement topography), it was revealed that the largest earthquakes that occurred in the region of the Central Kuril Islands in 2006, 2007, and 2009 were related to the block structure of the Earth’s crust. The aftershocks o...

The combined gravimetric, altimetric, and seismic data used for calculating the crust thickness beneath the Sea of Japan revealed its different types in this region: oceanic and continental with different degrees of destruction. It is shown that the crust thickness derived from satellite altimetry is well consistent with that calculated from the da...

Seven zircon fission-track ages and 30 magnetic susceptibilities were measured on welded pyroclastic rocks from the Bogopol and Sijanov Groups of the Cretaceous to Paleogene volcanic rocks in the southeastern part of the eastern Sikhote Alin volcano-plutonic belt, Far East Russia. The fission-track ages range from 42. 7 Ma to 64. O Ma which indicat...

The method of revealing probable areas of future strong earthquakes (“seismic gaps”) was first proposed with the Kuril‐Kamchatka island arc (KKA) as an example [1]. The method is based on the following principle: sources of the strongest ( M ≥ 7.7) earthquakes have a significant tendency not to overlap each other. Based on this principle, potential...

We present palaeomagnetic results from Lower Cretaceous rocks in Bikin area of the Alchan basin (46.5°N, 134.7°E), Sikhote Alin orogenic belt, Far Eastern Russia. A high-temperature magnetization component with maximum unblocking temperatures at about 590°C was isolated from six sites of dacite welded tuffs in the Albian Alchanskaya Formation. The...

In 1996, an airgun-ocean bottom seismometer survey was carried out in the northern part of the central Japan Basin. The crustal thickness in the central part is about 9 km, including a sedimentary layer with thickness of 1.5 km, and increases eastward. The obtained crustal structure is slightly different from those of typical ocean basins. The thic...

Four distinct components of natural remanent magnetization were isolated from a single site in welded tuffs in the Upper Cretaceous Kisin Group of the Sikhote Alin mountain range, Russia. In order to contribute toward a basis for an interpretation of multicomponent magnetization, rock magnetic experiments were performed on the welded tuffs. All fou...

The Japan Sea is a back-arc basin in the northwestern Pacific and is now one of the most well studied marginal seas in the world in terms of its seismic crustal structure. The Japan Sea seems to possess areas of various stages of back-arc opening process. Understanding of each stage is critical in reconstructing the back-arc opening process. One of...

Gravitational modeling was carried out on the basis of the results of geophysical research of recent years and the geodynamic state of the crust in the northwestern part of the Sea of Japan was computed. Crustal zoning was made more precise on the basis of the genetic types along a profile extending from the South Primorie shelf across the submarin...

Welded tuffs in the Upper Cretaceous Kisin Group have been collected for paleomagnetic study from 24 sites in Sikhote Alin, eastern Russia. Normal paleomagnetic directions from 11 sites are regarded as primary directions, whereas reversed paleomagnetic directions from 13 sites are ascribed to secondary origin. The normal directions of the Kisin Gro...

Welded tuffs in the Bogopol and Sijanov groups were sampled at 27 sites from 12 caldera formations in the Sikhote Alin mountain range around Kavalerovo (44.3°N, 135.0°E) for chronological and paleomagnetic studies. KAr age dates show that the welded tuffs erupted between 66 Ma and 46 Ma. All sites yield reliable paleomagnetic directions, with unblo...
