Kambalny
Kambalny (russian: Камбальный) is a stratovolcano located in the southern part of the Kamchatka Peninsula, Russia. It is the southernmost active volcano of Kamchatka. It has erupted mafic rocks. It has a summit crater as well as five cinder cones on its flanks which are the source of lava flows. The volcano probably formed during the early Holocene and aside from the summit crater also features an explosion crater on the southwestern side of the summit. Three large collapses of the edifice occurred around 6300 BP; between the first two volcanic activity restored the cone, while the third occurred on the ridge on which Kambalny was constructed. The longest of these landslides travelled . The total volume of these landslides, , is the largest of all Holocene landslides, but it was buried at Kambalny proper by later volcanic activity. The collapse scar in the ridge is still visible and was the site of later landslides when Kambalny volcano was active. Kambalny is part of ...

Kurile Lake
Kurile Lake (russian: Кури́льское о́зеро, Kuríl'skoye Ózero) is a caldera and crater lake in Kamchatka, Russia. It is also known as Kurilskoye Lake or Kuril Lake. It is part of the Eastern Volcanic Zone of Kamchatka which, together with the Sredinny Range, forms one of the volcanic belts of Kamchatka. These volcanoes form from the subduction of the Pacific Plate beneath the Okhotsk Plate and the Asian Plate. Before the Kurile Lake caldera formed, the Pauzhetka caldera was active during the Pleistocene, and was the origin of the 443,000 ± 8,000 years old Golygin ignimbrite. The Kurile Lake caldera erupted 41,500 years ago, and another small eruption occurred between 9,000 and 10,000 years ago; then 6460–6414 BC a very large eruption took place, forming the present-day caldera and the Kurile Lake ignimbrite and deposited ash as far as away. This eruption has a volume of , making it a VEI 7-class eruption and one of the largest during the Holocene. Subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamchatka Peninsula
The Kamchatka Peninsula (russian: полуостров Камчатка, Poluostrov Kamchatka, ) is a peninsula in the Russian Far East, with an area of about . The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and the Karaginsky Island, constitute the Kamchatka Krai of the Russia, Russian Federation. The vast majority of the 322,079 inhabitants are ethnic Russians, although about 13,000 are Koryaks (2014). More than half of the population lives in Petropavlovsk-Kamchatsky (179,526 in 2010) and nearby Yelizovo (38,980). The Kamchatka peninsula contains the volcanoes of Kamchatka, a World Heritage Site, UNESCO World Heritage Site. Geography Politically, the peninsula forms part of Kamchatka Krai. The southern tip is called Cape Lopatka. (Lopatka is Russian for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seismic Station
A seismometer is an instrument that responds to ground noises and shaking such as caused by earthquakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a recording device to form a seismograph. The output of such a device—formerly recorded on paper (see picture) or film, now recorded and processed digitally—is a seismogram. Such data is used to locate and characterize earthquakes, and to study the Earth's internal structure. Basic principles A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected. The relative motion between the weight (called the mass) and the frame provides a measurement of the vertical ground motion. A rotating drum is attached to the frame and a pen is attached to the weight, thus recording any ground motion in a seismogram. Any movement from the ground moves the frame. The mass tends not to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
