description Reventador fumaroles Overview
The Reventador fumaroles are persistent gas vents located on El Reventador, an active stratovolcano in the Ecuadorian Andes. These fumaroles release primarily steam and sulfur gases, creating visible plumes that can be observed from considerable distances. The volcanic activity intensified dramatically following the volcano's major eruption in 2002, which generated ash columns reaching 17 kilometers high. These ongoing fumarolic activities represent the continued degassing of the volcanic system.
help Reventador fumaroles FAQ
Where are the Reventador fumaroles?
They are gas vents in and around the crater of El Reventador, an active stratovolcano in Ecuador's Cordillera Real. The Smithsonian Global Volcanism Program lists the volcano at about 3,562 meters and describes fumaroles in the crater and concentric cracks near the rim.
What gases come from Reventador fumaroles?
Fumaroles mainly release water vapor and volcanic gases such as sulfur dioxide, with the exact mix changing as the hydrothermal system and eruption state change. A 1990 field report recorded abundant small fumaroles that were quiet and reached about 71 degrees Celsius.
Do Reventador fumaroles mean the volcano is erupting?
Not by themselves, because fumarolic activity can continue during a quieter interval and does not prove that lava is erupting at that moment. Reventador also has a history of stronger events, including the 2002 eruption that produced a 17-kilometer-high column.
Can I visit the Reventador fumaroles?
The vents are in an active, remote volcano rather than a normal developed attraction, and access can change with weather, ash, explosions, or official alerts. The Instituto Geofísico EPN and Ecuadorian authorities monitor the volcano, so current guidance matters more than a fixed itinerary.
