Kamchatka Peninsula - Wikipedia, the free encyclopedia The Kamchatka Peninsula is a part of the Russian Kamchatka Oblast (along with a part of the continent, the Komandorskiye Islands and Karaginsky Island). Kamchatka Peninsula (Russian: полуо́стров Камча́тка) is a 1,250-kilometer-long peninsula in the Russian Far East, with an area of 472,300 km². In early August 2005, the Priz class AS-28 Deep Submergence Rescue Vehicle of the Russian Navy was disabled in a submarine accident near Kamchatka and sunk to the seafloor, requiring an international effort to rescue the crew. en.wikipedia.org /wiki/Kamchatka   (399 words)

Kamchatka earthquakes Both earthquakes occurred at approximately the same location where the Pacific Plate subducts the Okhotsk Plate at the Kuril-Kamchatka Trench. Kamchatka earthquakes were a pair of megathrust earthquakes occurring off the coast of the Kamchatka Peninsula, in Russia on October 16, 1737, and on November 4, 1952, in the magnitude of 9.3 and 9.0 respectively, with resulting tsunamis following. The depth of the trench at the point of the earthquakes is 7000 - 7500 meters. www.firebird.cn /wiki/Kamchatka_earthquakes   (125 words)

Oceanic trench Trenches along with volcanic arcs and zones of earthquakes that dip under the volcanic arc as deeply as 700 km are diagnostic of convergent plate boundaries and their deeper manifestations, subduction zones. Trenches distant from an influx of continental sediments lack an accretionary prism, and the inner slope of such trenches is commonly composed of igneous or metamorphic rocks. Trenches are centerpieces of the distinctive physiography of a convergent plate margin. www.worldhistory.com /wiki/O/Oceanic-trench.htm   (3784 words)

IKIP: Island Info Volcanic activity and uplift in the region of the Lesser Kuril Ridge intensified during the Paleocene and Eocene as the Kula-Pacific Ridge was subducted into the Kuril-Kamchatka Trench, and it was probably during this period that the Lesser Kuril Ridge emerged from the sea (Kimura and Tamaki, 1985). This subduction zone initiated the formation of the Kuril-Kamchatka Trench and the subsequent volcanism that created the Academy of Sciences Rise (now located in the central Sea of Okhotsk) and the Lesser Kuril Ridge. The Greater Kuril Ridge includes the Shiretoko Peninsula of eastern Hokkaido, all of the remaining Kuril Islands, from Kunashir north to Shumshu, and the southern tip of the Kamchatkan Peninsula. artedi.fish.washington.edu /okhotskia/ikip/Info/geohist.html   (1389 words)

Kuril Islands - Wikipedia, the free encyclopedia The Kuril Trench is an oceanic trench that runs about 200 km east of the Kuril Islands. The Kuril Islands (Russian: Кури́льские острова́, Kuril'skie ostrova), also known as Kurile Islands, stretch northeast from Hokkaidō, Japan, to Kamchatka, separating the Sea of Okhotsk from the North Pacific Ocean. The Kuril Islands were inhabited by the Ainu from time immemorial until they were expelled from the northernmost by the Russians in the 18th century. www.leessummit.us /project/wikipedia/index.php/Kurile_Islands   (351 words)

innovations-report - Forum for Science, Industry and Business These eddies are generated to the east of Japan and move to the north along the Kuril-Kamchatka Trench involving water masses from the bottom to the surface. One of the eddies was an old-timer, it was moving along the Kuril-Kamchatka Trench to the northeast for a period of 5 years since 1986. On the basis of unique observations on eddies from Russian, Canadian, and Japanese ships, the scientists established that the eddies brought the increasing amounts of warm salty water from the southern parts of the ocean, and their dimensions and velocities grew considerably within the last decade. www.innovations-report.com /print/print_en01.php3?id=7868&ctyp=1   (487 words)

394 Petrographic, geochronological and structural evidence suggests that the Bani Hamid metamorphic sole is derived from Tethyan pelagic (Hawasina) and trench fill complex (Haybi) sediments, with intercalated basaltic extrusives, accreted to the base of the ophiolite during intra-oceanic subduction. The extensional mechanisms in the Ryukyu back-arc basin (IBE) and near the Manila Trench (MTF) reveal nearly trench-perpendicular extensions, with s3 axes trending N168°E and N86°E, respectively; s1 axes plunge 76° or steeper (normal faulting mode). The metamorphic sole of the Khawr Fakkan block of the Semail ophiolite, exposed in the Bani Hamid area of the United Arab Emirates, appears to represent the oldest preserved phase of metamorphism in the ophiolite belt, and is characterised by UHT assemblages in metasedimentary and metabasaltic material. camb.demonhosting.co.uk /JConfAbs/4/394.html   (12638 words)

Skiing the Pacific Ring of Fire and Beyond: Kamchatka & Kuril Islands Kamchatka is one of the most varied and active volcanic regions in the world. Kamchatka has long been cloaked in myth and mystery, extended over the last half century by its isolation as a secret Soviet military region closed to all foreigners. Only a few of the Kurils are inhabited, and access is quite difficult to all except the southernmost island, Kunashir (home to the strikingly beautiful somma-volcano of Tyatya). www.skimountaineer.com /ROF/Region.php?region=Kamchatka   (688 words)

S096706539787526.abstract.en Oceanic features detected along the basin-wide trajectory include a quasi-permanent anticyclonic eddy over the Kuril-Kamchatka Trench, open-ocean wind-driven inertial oscillations, coastal-trapped diurnal shelf waves, semidiurnal tidal currents, transient cyclonic and anti-cyclonic eddies, through-strait flows, and wave-like mesoscale meanders. A near-surface satellite-tracked drifter launched off the east coast of the Kuril Islands on September 4, 1993 began a 2.5-year odyssey across the North Pacific Ocean. The single drifter track delineates the dynamically-rich variability of upper ocean currents, emphasizes the marked difference in flow dynamics between boundary and open ocean regions, and provides a time-scale for the movement of surface waters across the entire North Pacific. www.elsevier.com /cdweb/journals/09670653/articles/44/11/S096706539787526.abstract.en   (104 words)

Geology.asp A massive earthquake caused the windward side of the Koolau volcano to break away and slide down the side of the volcano and into the deep sea. The linear arrangement of the Hawaiian chain resulted from the formation of a series of islands as the Pacific tectonic plate moved northwestward over a volcanic hot spot. This conveyor belt-like progression of islands raises the possibility that islands now eroded and sunken could have at one time supported life and provided colonists for newly arising islands to the southeast. cramp.wcc.hawaii.edu /Study_Sites/Oahu/Kaneohe_Sector/Jokiels_Illustrated_Scientific_Guide_to_Kaneohe_Bay/Geology.asp   (2001 words)

Sakhalin TWC For the period of 1958 - 1998 in Sakhalin and Kuril Isls there were registered 42 tsunami, 34 of them were generated in near-source zone (Kuril-Kamchatka Trench, Japan and Okhotsk seas) and 8 - in distant regions of the Pacific. Tsunami waves are generated not in all cases of occurring of major earthquakes near coast but considering that generation probability is high, Tsunami Warning are issued always when magnitude is greater or equal threshold (for the Kuril-Kamchatka Trenh, Japan and Okhotsk seas threshold is 7.0). In Kuril Isls 2-nd Kuril Strait (where Severo-Kurilsk is situated) is similar to such bay. www.science.sakhalin.ru /Tsunami/Index.html   (1510 words)

Deep current measurements at 38°N east of Japan While the transports were similar to those of the Izu-Ogasawara and Kuril-Kamchatka trenches, whose ends connect with the Japan Trench, the current structure resembles that at the Izu-Ogasawara Trench rather than that at the Kuril-Kamchatka Trench. Below 2000 m, the deep transports above the trench were southward 5.5 Sv and northward 13.5 Sv, and the boundary was at the deepest point of the trench. Its northward transport was estimated to be 6.2 Sv, and the total northward transport was estimated to be 19.7 Sv at 38°N. A pair of oppositely flowing deep currents is confirmed in the Japan Trench. www.agu.org /pubs/crossref/2005/2004JC002288.shtml   (279 words)

Kuril Islands --  Britannica Concise Encyclopedia - The online encyclopedia you can trust! The Kurils were originally settled by the Russians in the 17th–18th centuries. The archipelago extends for 750 miles (1,200 km) from the southern tip of the Kamchatka Peninsula (Russia) to the northeastern corner of Hokkaido island (Japan) and separates the Sea of Okhotsk from the Pacific Ocean.

From the history of far eastern coral faunas study, VII International Congress Deep-sea solitary scler­actinian corals from Kuril-Kamchatka and Aleutian Trenches were studied by N.B. Keller in 1976 – 1997. Nevertheless, the rich asso­ciation of pennatulides (Kophobelemnon, Umbellula) was discovered in Kuril-Kam­chatka Trench in 6100 – 6200 m. The facts show the morphological variability of young deep-sea inhabitants and, on the contrary, the strong specialization of the ancient corals. www.vitiaz.ru /congress/en/thesis/120.html   (506 words)

Okhotsk Plate It is bounded on the north by the North American Plate, on the east by the Pacific Plate at the Kuril-Kamchatka Trench and the Japan Trench, on the south by the Philippine Plate at the Nankai Trough, on the west by the Eurasian Plate, and possibly on the southwest by the Amurian Plate. The Okhotsk Plate is a continental tectonic plate covering the Sea of Okhotsk, the Kamchatka Peninsula, and Eastern Japan. It was considered a part of the North American Plate, but recent studies show that it is an independent plate. www.tocatch.info /en/Okhotsk_Plate.htm   (112 words)

Eddies advected by time-dependent Sverdrup circulation in the western boundary of the subarctic North Pacific It has been reported that several eddies frequently exist along the Kuril-Kamchatka Trench (K-K Trench, hereafter), the western boundary of the subarctic North Pacific. Lagged correlation maps of the altimeter-derived sea level anomalies (SLAs) along the trench indicate that the southern eddies on the whole move northeastward along the K-K Trench and the northern eddies, on the other hand, move southwestward. The time series of the tracked 7 eddies shows similar seasonal variation to those of the first empirical orthogonal function (EOF) of the SLA maps and to those of the Sverdrup transport at 40°N. In addition, when more than two eddies remotely exist in the studied area, they show coherent moving patterns. www.agu.org /pubs/crossref/2003/2003GL017652.shtml   (291 words)
