Masaya volcano 25 km SE from Managua is one of Nicaragua's most active and usual volcanoes.
In contrast to most other volcanoes in subduction zones, it has been erupting mainly fluid basaltic lava. At the time of the Spanish Conquistadors, it contained an active lava lake and it is reported that there were attempts to extract the volcano's molten "gold."
Masaya is a complex consisting of a 6×11.5 km large caldera with steep, up to 300 m high walls, and a group of young cones at the NW end including Nindirí and Masaya volcano proper. There are multiple summit craters including the currently active Santiago crater, the site of the current activity. caldeira 635 m / 2,083 ft Nicaragua, 11.98°N / -86.16°W Condition actuelle: en éruption (4 sur 5) Masaya webcams / données en temps réel | ReportsMasaya livres
