Concepción (volcano) in the context of "Mudstone"

Concepción (Spanish: Volcán Concepción), also known by its aboriginal name Omeyatecihua from the Nawat language, 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 1,610 m (5,280 ft) tall and rests on a 1-kilometer-thick (0.62 mi) thick base of Quaternary lacustrine mudstones. It is considered a "pristine" volcano because there has been no influence of other volcanoes on its growth, and its cone is highly symmetrical. 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 cause more volcanic growth. This affects the magma chamber which begins the cycle again with growth because of magmatic flow.
