Geological summary

Volcán Concepción is a symmetrical basaltic-to-dacitic stratovolcano that forms the NW half of the dumbbell-shaped island of Ometepe in Lake Nicaragua and is connected to neighboring Madera volcano by a narrow isthmus. A steep-walled summit crater is 250 m deep and has a higher western rim. N-S-trending fractures on the flanks have produced chains of spatter cones, cinder cones, lava domes, and maars located on the NW, NE, SE, and southern sides extending in some cases down to Lake Nicaragua. It was constructed above a basement of lake sediments, and the modern cone grew above a largely buried caldera, a small remnant of which forms a break in slope about halfway up the N flank. Frequent explosive eruptions during the past half century have increased the height of the summit significantly and have kept the upper part of the volcano unvegetated.

From Wikipedia

Concepción, also known by its aboriginal name Omeyatecihua from the Nawat language, is one of two volcanoes that form the island of Ometepe, which is situated in Lake Nicaragua in Nicaragua, Central America.
