2006 Kamchatka Earthquakes
The 2006 Kamchatka earthquake occurred on . This shock had a moment magnitude of 7.6 and a maximum Mercalli intensity of X (''Extreme''). The hypocenter was located near the coast of Koryak Autonomous Okrug at an estimated depth of 22 km, as reported by the International Seismological Centre. This event caused damage in three villages and was followed by a number of large aftershocks. Two M6.6 earthquakes struck on April 29 at 16:58 UTC and again on May 22 at 11:12 UTC. These earthquakes caused no deaths; however, 40 people were reported injured. Tectonic setting The northern part of the Kamchatka Peninsula lies away from the convergent boundaries of the Kuril–Kamchatka Trench and the Aleutian Trench but across the boundary between two blocks within the North American Plate, the Kolyma-Chukotka and Bering Sea microplates. This boundary accommodates both active shortening and right lateral strike-slip across a series of large SW–NE trending faults. Earthquake The focal ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Kamchatka Krai
Kamchatka Krai ( rus, Камча́тский край, r=Kamchatsky kray, p=kɐmˈtɕatskʲɪj kraj) is a federal subject of Russia (a krai), situated in the Russian Far East, and is administratively part of the Far Eastern Federal District. Its capital and largest city is Petropavlovsk-Kamchatsky, home to over half of its population of 322,079 ( 2010). Kamchatka Krai was formed on July 1, 2007, as a result of the merger of Kamchatka Oblast and Koryak Autonomous Okrug, based on the voting in a referendum on the issue on October 23, 2005. The okrug retains the status of a special administrative division of the krai, under the name of Koryak Okrug. The Kamchatka Peninsula forms the majority of the krai's territory, separating the Sea of Okhotsk and the Bering Sea in the Pacific Ocean. The remainder is formed by a minor northern mainland portion, Karaginsky Island, and the Commander Islands in the Bering Sea. It is bordered by Magadan Oblast to the west and Chuk ...

History Of The 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 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 UNESCO World Heritage Site. Geography Politically, the peninsula forms part of Kamchatka Krai. The southern tip is called Cape Lopatka.

Kamchatka Earthquakes
Many major earthquakes have occurred in the region of the Kamchatka Peninsula in far eastern Russia. Events in 1737, 1923 and 1952, were megathrust earthquakes and caused tsunamis. There are many more earthquakes and tsunamis originating from the region. Tectonic setting The southern part of the Kamchatka peninsula lies above the convergent plate margin where the Pacific Plate is subducting beneath the Okhotsk Plate along the line of the Kuril–Kamchatka Trench. The rate of convergence between the two plates is about 86 mm per year. Earthquakes are generated by rupture along the megathrust boundary between the two plates, within the descending Pacific Plate and within the overriding Okhotsk Plate. The northern part of the peninsula lies away from the convergent boundaries of the Kuril–Kamchatka Trench and the Aleutian Trench but across the boundary between two blocks within the North American Plate, the Kolyma-Chukotka and Bering Sea microplates.

En Echelon
An echelon formation () is a (usually military) formation in which its units are arranged diagonally. Each unit is stationed behind and to the right (a "right echelon"), or behind and to the left ("left echelon"), of the unit ahead. The name of the formation comes from the French word échelon, meaning a rung of a ladder, which describes the shape that this formation has when viewed from above or below. Military formation Use of the formation dates back to ancient infantry and cavalry warfare, as an alternative to column, line-abreast, or phalanx (box) formations. One of its earliest uses was at the Battle of Leuctra, when the Thebans attacked the Spartan right with a column 48 men deep while their weaker center and right were repelled. The echelon formation may have been used by Hannibal at the Battle of Cannae, Alexander the Great at the Battle of Gaugamela, Frederick II of Prussia, and the Confederate army at the Battle of Gettysburg. The tactic still persists and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Rupture
In seismology, surface rupture (or ground rupture, or ground displacement) is the visible offset of the ground surface when an earthquake rupture along a fault affects the Earth's surface. Surface rupture is opposed by buried rupture, where there is no displacement at ground level. This is a major risk to any structure that is built across a fault zone that may be active, in addition to any risk from ground shaking. Surface rupture entails vertical or horizontal movement, on either side of a ruptured fault. Surface rupture can affect large areas of land. __TOC__ Lack of surface rupture Not every earthquake results in surface rupture, particularly for smaller and deeper earthquakes. In some cases, however, the lack of surface effects is because the fault that moved does not reach the surface. For example, the 1994 Northridge earthquake had a moment magnitude of 6.7, caused major damage in the Los Angeles area, occurred at below the Earth's surface, but did not cause surface ...
