Concepción (volcano) in the context of Nawat

The Central American Volcanic Arc (often abbreviated to CAVA) is a chain of volcanoes which extends parallel to the Pacific coastline of the Central American Isthmus, from Mexico to Panama. This volcanic arc, which has a length of 1,100 kilometers (680 mi) is formed by an active subduction zone, with the Cocos plate subducting underneath the Caribbean plate, the North American plate and the Panama plate. Volcanic activity is recorded in the Central American region since the Permian. Numerous volcanoes are spread throughout various Central American countries; many have been active in the geologic past, varying in intensity of their activity according to different factors.

Maderas (Spanish: Volcán Maderas), also known by its aboriginal name Omeyateite from the Nawat language, is a volcano in Nicaragua. With a height of 1,394 metres (4,573 ft), it is the smaller of the two volcanoes which make up the island of Ometepe in Lake Nicaragua. Unlike Concepción, the other volcano on the island, Maderas has not been active in historical times. Its crater contains a crater lake.

The slopes of Maderas are one of the few places on the Pacific side of Nicaragua where cloud forests grow. The only other place where this ecosystem can be found is the Mombacho volcano. Cloud forests are characterized by a rich plant and animal life, made possible by the high levels of humidity in the climate. Prehistoric petroglyphs have been found at the Maderas volcano.

Ometepe is an island formed by two volcanoes rising out of Lake Nicaragua, located in the Rivas Department of the Republic of Nicaragua. Its name derives from the Nawat words ome (two) and tepetl (mountain), meaning "two mountains". It is the largest island in Lake Nicaragua.

The two volcanoes (Concepción and Maderas) are joined by a low isthmus to form one island. Ometepe has an area of 276 square kilometres (107 sq mi). It is 31 kilometres (19 mi) long and 5 to 10 kilometres (3.1 to 6.2 mi) wide. The island has an economy based on livestock, agriculture, and tourism. Plantains are the major crop.
