Volcán Azul volcano

Volcán Azul (also known as Volcán Blue) a group of 3 cinder cones located on the Atlantic coastal plain of Nicaragua. The volcanic cones are in an area covered by dense rainforest and were discovered during an aerial survey in the 1960s.

Note: There is another Cerro Azul volcano in Chile.

Background:

The youthful trachybasaltic cinder cones are located south of the Río Curinhuás and west of Pearl Lagoon. The cones have well-defined, steep-walled craters which are about 50-60 m across. The easternmost crater is open to the west, the other 2 are circular.
Based on the fresh vegetation and relatively low vegetation cover, it is thought that they could have formed only a few thousands years ago.
Other trachybasaltic to trachytic Quaternary cones along the central Nicaraguan Atlanatic coastal plain are found at Pearl Lagoon and Kukra Hill.
