Concepción

Concepcion

Stratovulcano · Nicaragua · 1700 m

Concepción is one of Nicaragua's most active volcanoes. It forms the NW half of Ometepe island in Lake Nicaragua and is seen here from the SE from the isthmus connecting it to Madera volcano, which forms the SE end. Spatter cones, and scoria cones have formed during flank eruptions. Concepción has had frequent recent moderate explosive eruptions, many of which have originated from a summit crater.

Sintesi geologica

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.

Sintesi da Wikipedia
