Land of volcanoes and geological
Seismicity [edit]. Earthquakes that affect Ecuador can be divided into those that result from movement on the subduction interface along the plate boundary, those that result from deformation within the South American and Nazca Plates and those that are associated with active volcanoes. Ecuador lies within the Northern Volcanic Zone where the subduction zone is moving at a rate of 7 cm/yr to the east-northeast, significantly oblique to the trend of this segment of the Andes. Let’s begin with Quito. Wikepedia says of Quito: San Francisco de Quito, most often called Quito, is the capital city of Ecuador in northwestern South America. It is located in north-central Ecuador in the Guayllabamba river basin, on the eastern slopes of Pichincha,[1] an active stratovolcano in the Andes mountains. If earthquakes terrify you, then you may want to avoid Ecuador and the entire ring of fire. The US Geological survey glossary describes the Ring of Fire: The “Ring of Fire”, also called the Circum-Pacific belt, is the zone of earthquakes surrounding the Pacific Ocean — about 90% of the world’s earthquakes occur there. The main active fault zones of Ecuador are SSW-NNE trending dextral strike-slip faults running parallel to the main subdivisions of the Andes, two major SW-NE dextral strike-slip zones, the Pallatanga and Chingual faults, and north-south trending reverse faults such as the Quito fault. Ecuador lies within the Northern Volcanic Zone where the subduction zone is moving at a rate of 7 cm/yr to the east-northeast, significantly oblique to the trend of this segment of the Andes. Publisher. A+E Networks. Quito, Ecuador, the site of many powerful earthquakes through the years, suffers one of its worst when a tremor kills 5,000 people and destroys some of the most famous buildings in South America, on this day in 1859. Quito’s history of earthquakes in modern times began with a monster tremor on February 4, 1797.  Back to Top. Database. The purpose of the database is to provide fault data that can be readily accessed using a variety of search parameters. For this database, we anticipate that the user would want search-and-retrieve capabilities from a personal computer. The fault and fold data will be released in several forms. This open-file report constitutes a traditional hard-copy catalog (database and map) for Ecuador. The Ecuador data will eventually be part of a larger relational computer database for the Western Hemisphere that should be available on the World Wide Web (WWW). The map of Quaternary faults and folds of Ecuador was compiled on an overlay using the Ecuador geologic map as a base; the faults were digitized at a scale of 1:1,250,000. The fault and fold data will be released in several forms. This open-file report constitutes a traditional hard-copy catalog (database and map) for Ecuador. The Ecuador data will eventually be part of a larger relational computer database for the Western Hemisphere that should be available on the World Wide Web (WWW). Ecuador is a land of volcanoes and geological faults so Ecuador does have earthquakes. Here is an excerpt from a full report just emailed to our Ecuador Living subscribers. The recent earthquake in Haiti sent many readers scuttling to their keyboards so they could ask about earthquakes in Ecuador. If earthquakes terrify you, then you may want to avoid Ecuador and the entire ring of fire. The US Geological survey glossary describes the Ring of Fire: The “Ring of Fire”, also called the Circum-Pacific belt, is the zone of earthquakes surrounding the Pacific Ocean — about 90% of the world’s earthquakes occur there. Earthquakes within the downgoing Nazca Plate, such as the M w 7.1 event of August 2010, are generally too deep to cause significant damage in Ecuador although they are felt over a wide area. Ecuador lies within the Northern Volcanic Zone where the subduction zone is moving at a rate of 7 cm/yr to the east-northeast, significantly oblique to the trend of this segment of the Andes. SYNOPSIS AND GEOLOGIC SETTING: The structure belongs to the most important fault system in NW Ecuador. It controls the uplift of basement rocks and the formation of the coastal mountains. The southern section of the Ca averal fault system [EC-07c] is separated from the central section by a 20 km gap. The fault and fold data will be released in several forms. This open-file report constitutes a traditional hard-copy catalog (database and map) for Ecuador. The Ecuador data will eventually be part of a larger relational computer database for the Western Hemisphere that should be available on the World Wide Web (WWW).
