Hydrothermally altered ground in the foreground is part of 2 km² geothermal field on the southern flank of Momotombo volcano. The Patricio Arguello Ryan geothermal plant at one point produced 25% of the electrical power of Nicaragua. Summit crater fumarolic activity increased following development of the geothermal field.
