Onekotan
Onekotan (russian: Онекотан; Japanese 温禰古丹島; Onekotan-tō, occasionally Onnekotan-tō, ain, オネコタン or オネコタㇴ) is an uninhabited volcanic island located near the northern end of the Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. Its name is derived from the Ainu language for "large village”. It is the second largest island, after Paramushir, in the northern subgroup of the Kurils. It is administratively included in the Severo-Kurilsky District of Sakhalin oblast, Russia. Geography and geology Onekotan is roughly rectangular, with a length of , and a width ranging from .

Nemo Peak
Nemo Peak (russian: Пик Немо) is a stratovolcano located at the northern end of Onekotan Island, Kuril Islands, Russia. It is truncated by two nested calderas, with the cone of Nemo Peak itself rising in the southwest end of the youngest caldera and a crater lake partially filling the northeast part, named Ozero Chernoye. Geography Nemo Peak lies on Onekotan Island, in the Kuril Islands. Nemo Peak lies on the northern end of the island; the southern end is occupied by Tao-Rusyr Caldera. These two volcanoes together have erupted about of tephra, covering the entire seafloor of the Sea of Okhotsk. Geology Nemo Peak has formed several calderas. Two older ones reach diameters of and overlap each other, with an average elevation of the floor of . The Sovetskii ridge limits these calderas to the east. A pre-Nemo volcano is known as Mednyi. Glacial erosion has affected the older volcanic centres. Ignimbrites fill these calderas. Within this caldera lies a stratovolc ...

Tao-Rusyr Caldera
Tao-Rusyr Caldera (russian: Тао-Русыр) is a stratovolcano located at the southern end of Onekotan Island, Kuril Islands, Russia. It has 7.5 km wide caldera formed during a catastrophic eruption less than 10,000 years ago (reported ages range from 5,550 to 9,400 Before Present). The waters of Kol'tsevoe Lake (russian: Кольцевое озеро, Ring Lake) fill the caldera, along with a large symmetrical andesitic cone, Krenitsyn Peak, that rises as an island within the lake. This volcano was named after Captain Pyotr Krenitsyn of the Imperial Russian Navy. The most recent eruption, in 1952, formed a small lava dome on the island's coast. Krenitsyn Peak has a summit crater 350 m wide and is the highest point of the volcano and on the entire Onekotan Island. Another caldera, Nemo Peak, lies at the northern end of the island, and it also contains a central cone and crater lake. The caldera forming eruption yielded about of material and destroyed the upper parts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kharimkotan
Kharimkotan (russian: Харимкотан); Japanese 春牟古丹島; Harimukotan-tō, alternatively Harumukotan-tō or 加林古丹島; Karinkotan-tō) is an uninhabited volcanic island located from Onekotan near the northern end of the Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. Its name is derived from the Ainu language, from “village of many Cardiocrinum”. Geology Kharimkotan is roughly oval, measuring by with an area of . The landscapes of the island are quite diverse; however, a significant part of the island's surface is covered with fine yellow ash, resembling desert dunes. On the north-western cape are the ruins of an Ainu village and in the north of the island, on the shore of Severgin Bay, is the abandoned settlement of Severgino. There are a number of small freshwater lakes. Kharimkotan is separated by the Sixth Kuril Strait from Onekotan, located 15 kilometers to the northeast, and by the Severgin Strait from Shiashkotan, lo ...

Makanrushi
Makanrushi (russian: Маканруши; Japanese 磨勘留島; Makanru-tō) is an uninhabited volcanic island located near the northern end of the Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. Its name is derived from the Ainu language. Geology Makanrushi is roughly rectangular, with an area of The island consists of a dormant or extinct stratovolcano, Pik Mitaka -(russian: влк.Митака ; Japanese 三高山; ''Mitakayama''), which rises to above sea level. The island has steep cliff sides and no sandy beaches, making landing very difficult and dangerous even in calm weather. Makanrushi is 28 km away from Onekotan. Makanrushi thus lies behind the main currently-active arc of Kuril Island volcanoes. History Makanrushi appears to have never been inhabited. It appears on an official map showing the territories of Matsumae Domain, a feudal domain of Edo period Japan dated 1644, and these holdings were officially confirmed by the Tok ...

Fourth Kuril Strait
The Fourth Kuril Strait () is a very deep strait separating the islands of Onekotan and Paramushir in the Kuril Islands, Russia. It is 46.7 km (about 29 mi) wide. It was formerly known as the Amphitrite Strait. The flood tidal current in the strait sets west-northwest, while the ebb flows in the opposite direction. These currents may reach over two knots.National Geospatial-Intelligence Agency. (2014). ''Sailing Directions (Enroute): East Coast of Russia''. U.S. Government, Springfield, Virginia. History Between 1849 and 1874, the strait was the most common route for American whaleships entering and exiting the Sea of Okhotsk on their way to and from cruises for bowhead and right whales Right whales are three species of large baleen whales of the genus ''Eubalaena'': the North Atlantic right whale (''E. glacialis''), the North Pacific right whale (''E. japonica'') and the Southern right whale (''E. australis'').

Pyotr Krenitsyn
Pyotr Kuzmich Krenitsyn (russian: Пётр Кузьмич Креницын) (1728 – July 4, 1770), spelt "Krenitzin" in the United States, was a Russian explorer and Captain/Lieutenant of the Imperial Russian Navy. Following Vitus Bering's 1741 tragic venture he was the first to conduct an expedition to Alaska and the Aleutians. Krenitsyn was sent, together with Mikhail Levashev, by Russian Empress Catherine II to explore the northern parts of the Pacific Ocean and particularly the area around the Bering strait in four ships. Krenitsyn was the commander of the ship ''St. Catherine'' and Levashev commanded the ship ''St. Paul''.Coxe, William. Account of the Russian Discoveries Between Asia and America. Life Krenitsyn and Levashev surveyed the eastern part of the Aleutian island chain until the cold weather set in. Krenitsyn wintered in the strait between Unimak and the Alaska Peninsula.

Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute.

Caldera Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ...
