Asperity distribution and earthquake occurrence in the southern Kurile Islands arc [PDF]

open access: yesPhysics of the Earth and Planetary Interiors, 1987
The seismicity in the southern Kurile Islands arc is characterized by a complex overlapping of aftershock zones of a few great and many large earthquakes (Ms ≧ 7.0). The spatial relationships of these aftershock zones can be explained in terms of a simple pattern of fault plane heterogeneity.

SPECTRAL ANALYSIS OF ENERGY DISTRIBUTION AT TSUNAMI WAVE PROPAGATION IN OKHOTSK SEA BASIN [PDF]

open access: yesScience of Tsunami Hazards, 2017
The presence of residual subduction zone under Kuril island arc makes a region of Kuril ridge islands be potential seismic-danger since underwater earthquakes in subduction zone with magnitude М > 6 are usually tsunamigenic.

K-Ar dating of magmatic rocks from the Urup Island, Kuril Island Chain

open access: yes, 2004
An isotope-geochronological study of Neogene-Quaternary igneous rocks from the Urup Island (Greater Kuril Ridge) was carried out. It was established that magmatic activity in the island developed during the last 10 my and it was not interrupted by long ...

Reconstructing Along‐Strike Variability of Retreating Accretionary Margins Using Detrital Isotopic Proxies in Patagonia and Japan

open access: yesTectonics, Volume 45, Issue 9, September 2026.
Abstract Retreating accretionary systems are common features of convergent plate margins. They are characterized by upper plate extension and backarc basin formation, which often forms diachronously and asymmetrically along‐strike. This study tests the hypothesis that this along‐strike variability in backarc basin formation is reflected in detrital and

ON TRANSVERSE PETROGEOCHEMICAL ZONALITY OF MESOZOIC VOLCANITES IN THE ORE FIELDS OF THE TRANSBAIKALIAN SEGMENT OF THE MONGOLO-OKHOTSK FOLD BELT

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2020
The relevance of the work is caused by the need to study the regularities of mineralization formation in the Transbaikalian segment of the Mongol–Okhotsk fold belt. The aim of the work is to establish the conditions of formation, to identify the presence

Upper mantle properties of the southern part of the Kuril Island arc according to detailed seismological data

open access: yes, 1965
The southern part of the Kuril Islands is typical of an island arc. The structure of the earth's crust in that region has been well studied by seismic sounding. The present paper gives a short synthesis of data about the properties of the mantle obtained

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 2—Model Evaluation and Uncertainty Analysis

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Despite millions of ship soundings, bathymetry from satellite derived gravity is still necessary to fill in approximately three quarters of the global oceans. The methods used to carry out this inference have not changed significantly since the 1990s; however new methodology involving Machine Learning (ML) improves the bathymetric predictions ...
