Volcán Azul (Volcán Blue) consists of three youthful trachybasaltic cinder cones on the jungle-covered Atlantic coastal plain of Nicaragua that were first noted by geologists during an aerial overflight in the 1960s. The three cones, located south of the Río Curinhuás and west of Pearl Lagoon, each have well-defined, steep-walled craters about 50-60 m across. In contrast to the circular rims of the other two cones, the rim of the easternmost cone is breached to the west. The well-defined craters and unusually low vegetation in an area of heavy rainfall and rapid weathering led Williams and McBirney (1965) to estimate that the cones were probably no more than a few thousand years old. Other trachybasaltic to trachytic Quaternary cones along the central Nicaraguan Atlanatic coastal plain are found at Pearl Lagoon and Kukra Hill.
The Global Volcanism Program is not aware of any Holocene eruptions from Volcán Azul. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Volcán Azul page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

|Volcán Azul (Volcán Blue) consists of three youthful cinder cones on the jungle-covered Atlantic coastal plain of Nicaragua. The cones are located at the lower left, west of Pearl Lagoon (right-center) and south of both the Río Grande de Matagalpa (which flows from the upper left to form the small point north of Pearl Lagoon) and the Río Curinhuás (left-center), which flows into the northern end of the lagoon. The three cones, each of which have well-defined, steep-walled craters, were first noted by geologists during an aerial overflight in the 1960s.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
