2007 Aysén Fjord Earthquakes
The 2007 Aysén Fjord earthquakes occurred in Aisén Fjord, Chile from January 22 – April 22. The biggest occurred at 1:53 p.m. (local time) on April 21 and reached a felt intensity of VII (''Very strong'') on the Mercalli intensity scale. On the moment magnitude scale, the earthquake reached a magnitude of 6.2. Ten people disappeared due to a tsunami caused by a landslide, according to ONEMI (Chile's National emergency office), but three bodies were found on April 22 by the Chilean Navy. Earthquakes Starting January 22, Aysén Fjord suffered a series of minor earthquakes. The greatest before April 21 reached VI (''Strong'') on the Mercalli intensity scale and occurred at 3:44 p.m. on April 14. Local fishermen reported seeing steam rising from the fjord. The earthquake expanded to several zones of the country. At 6:22 a.m. (local time) on April 22, an intense earthquake was felt in Santiago, reaching II (''Weak'') on the Mercalli intensity scale.

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 ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

El Mercurio
''El Mercurio'' (known online as ''El Mercurio On-Line'', ''EMOL'') is a Chilean newspaper with editions in Valparaíso and Santiago. Its Santiago edition is considered the country's newspaper of record and it is considered the oldest daily in the Spanish language currently in circulation. ''El Mercurio'' is owned by El Mercurio S.A.P. (''Sociedad Anónima Periodística'' 'joint stock news company'), which operates a network of 19 regional dailies and 32 radio stations across the country. History The Valparaíso edition of ''El Mercurio'' was founded by Pedro Félix Vicuña ( Benjamín Vicuña Mackenna's father) on September 12, 1827, and was later acquired by Agustín Edwards Ross in 1880. The Santiago edition was founded by Agustín Edwards Mac Clure, son of Edwards Ross, on June 1, 1900. In 1942 Edwards Mac Clure died and his son Agustín Edwards Budge took over as president.

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California.

International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collecti ...

Riñihuazo
The Riñihuazo is the name given to the landslide damming of Riñihue Lake on 22 May 1960, after a landslide caused by the Great Chilean earthquake blocked its outflow. According to the chronicler Mariño de Lobera a similar event occurred after the 1575 Valdivia earthquake. During the Great Chilean earthquake, several landslides near Tralcán Mountain blocked the outflow of Riñihue Lake at (). Riñihue Lake is the lowest of the Seven Lakes chain and receives a constant inflow from the Enco River. The blocked San Pedro River, which drains the lake, passes through several towns and the city of Valdivia before finally reaching Corral Bay. Because the San Pedro River was blocked, the water level of Riñihue Lake started to rise quickly. Each meter the water level rose was equivalent to 20 million cubic meters, which meant that 4.8 cubic kilometers of water would release into the San Pedro River (easily overpowering its flow capacity of 400 cubic meters per second) if it ...

List Of Earthquakes In Chile
__NOTOC__ Chile lay in a region which is adjacent to the fast-moving Nazca Plate, and has high tectonic activity. The records for earlier centuries are apparently incomplete. Of the world's 46 known earthquakes with M ≥ 8.5 since the year 1500, one-third occurred in Chile and are shown in the map to the side. Some virtually have the same epicenters like the 1604 and 1868 (in Arica), the 1730 and 1822 (in Valparaíso), the 1751 and 1835 (in Concepción), and the 1575 and 1837 (in Valdivia). The strongest known recorded in modern times was also in Chile, the 1960 Valdivia earthquake.

Liquiñe-Ofqui Fault
The Liquiñe-Ofqui Fault is major geological fault that runs a length of roughly in a NNE-SSW orientation and exhibits current seismicity. It is located in the Chilean Northern Patagonian Andes. It is a dextral intra-arc strike-slip fault. Most large stratovolcanoes of the Southern Volcanic Zone of the Andes are aligned by the fault which allows for the movement of magma and hydrothermal fluids. The fault crosses several transverse faults including the Mocha-Villarrica Fault Zone (MVFZ) and the Biobío-Aluminé Fault Zone. The fault have had periods of ductile deformation associated to pluton emplacement be it either at great depths or by shallow intrusions. The forces that move the fault are derivative of the oblique subduction offshore Chile's coast. This leads to partition of deformation between the subduction zone, the fore-arc and the intra-arc region where the fault lies.There is evidence that the fault broke as a 9.07 subevent in the 1960 Valdivia earthquake.

Puerto Chacabuco
Puerto Chacabuco is a Chilean town in Aisén commune. Administratively it belongs to Aysén Province in Aysén del General Carlos Ibáñez del Campo Region and is located at the head of Aisén Fjord. It is the main port of the region, a port of call for ships sailing to the Laguna San Rafael National Park and the terminus of a Navimag ferry service from Puerto Montt. Before the great burnings of the Patagonian forests and the eruption of Mount Hudson volcano in 1991 Puerto Aisén was the main port in the Aisén Fjord, but the ashes and earth erosion decreased the navigability of Aisén River and the port had to be moved further to the coast where Puerto Chacabuco now stands. Puerto Chacabuco is named after the corvette ''Chacabuco'' with which Enrique Simpson explored the fjords and archipelagoes of Aysén Region in the 1870s. The ship is in turn named after the Battle of Chacabuco in 1817 during the Chilean Independence War. See also * List of towns in Chile This article ...
