Concepción is one of two volcanoes (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 and rests on a 1-km-thick base of Quaternary lacustrine 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 weaknesses of the crust that the volcano rests on. As it grows from additional magma flow, the volcano grows in mass and exerts 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.[2]

Since 1883, Concepción has erupted at least 25 times; its last eruption was on 9 March 2010.[3] Concepción's eruptions are characterized by frequent, moderate-sized explosions. Active fumaroles are present just north of Concepción's summit crater.
