description Almolonga Fumaroles Overview
The Almolonga fumaroles are steam and gas vents in Guatemala's Cerro Quemado-Zunil geothermal area. The site is part of a volcanic and hydrothermal landscape, and a 1981 exploration well recorded a temperature of 260°C at depth. Fumaroles are surface expressions of geothermal systems, where heated fluids and gases escape through fractures or permeable ground, so the name is used in geological descriptions of the area's active heat and gas release.
help Almolonga Fumaroles FAQ
Where are the Almolonga fumaroles?
The Almolonga fumaroles are in Guatemala’s Cerro Quemado-Zunil geothermal area. The site lies within the volcanic and hydrothermal landscape associated with Volcán de Almolonga.
How hot is the Almolonga geothermal system?
A recorded bottom-hole temperature reached about 260°C in 1989. That measurement came from a geothermal exploration well rather than from the surface air at a fumarole.
What do the Almolonga fumaroles indicate?
They are surface vents where steam and volcanic gases escape from the geothermal system. Their presence, together with hot springs and mud pools, shows that heat and fluids remain active underground.
Are the Almolonga fumaroles safe to visit?
Fumarolic areas can contain very hot ground and harmful gases, even when the surface looks quiet. Visitors should follow local access rules and avoid approaching vents or geothermal wells.
