'''Concepción''' is one of two [[volcano]]es (along with [[Maderas]]) that form the island of [[Ometepe]], which is situated in [[Lake Nicaragua]] in [[Nicaragua]], [[Central America]].
Concepción is an active [[stratovolcano]] that forms the northwest part of the Isla de [[Ometepe]]. Concepción is 1600 m tall that rests on a 1-km-thick base of [[quaternary]] [[Lacustrine plain|lacustrine]] [[Mudstone|mudstones.]] It is considered a "pristine" volcano because there has been no influence of other volcanoes on its growth. The growth of the volcano comes in phases based on in weaknesses of the crust that the volcano rests on. As it grows from additional magma flow, the volcano grows in weight and pressure on the crust. This causes shifts which in turn causes more volcanic growth. This affects the magma chamber which begins the cycle again with growth because of magmatic flow<ref>{{Cite journal|title = The volcano-tectonic evolution of Concepción, Nicaragua|url = http://link.springer.com/article/10.1007/s00445-002-0256-8|journal = Bulletin of Volcanology|date = 2003-05-01|issn = 0258-8900|pages = 248-266|volume = 65|issue = 4|doi = 10.1007/s00445-002-0256-8|language = en|first = Andrea|last = Borgia|first2 = Benjamin van Wyk de|last2 = Vries}}</ref>.
Concepción is an active [[stratovolcano]] that forms the northwest part of the Isla de [[Ometepe]]. Since 1883, Concepción has erupted at least 25 times; its last eruption was on 9 March 2010.<ref>{{cite web|url=http://www.abc.net.au/news/stories/2009/12/12/2769772.htm|author=ABC News|title=Volcano eruption covers villages in ash|accessdate=2009-12-11}}</ref> Concepción's eruptions are characterized by frequent, moderate-sized explosions. Active [[fumaroles]] are present just north of Concepción's summit crater.▼
