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.

According to local press articles referring to information from INETER, the volcano's activity is on the rise, with "lava being close to the surface". The main crater of the volcano appears covered with debris from rockfalls from the crater walls, but visible incandescence, strong degassing sounds and small flames (from combusting gasses) jetting from between cracks on the floor, suggest that lava might be not far underneath and could again lead to the formation of a new lava lake, last observed in 1999. On the other hand, seismic activity has been at low levels and not shown significant variations recently, not suggesting that significant movements of magma towards the surface have taken place. Also, the incandescence of the vent at the main crater has been there for a number of years already. ---
