Geological Summary

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 Volcan Azul. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Volcan 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.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
