description Tacaná Fumaroles Overview
The Tacaná fumaroles are geothermal vents located on the slopes of the Tacaná volcano, a stratovolcano on the border between Mexico and Guatemala. These features emit steam and volcanic gases, with a significant increase in activity occurring during a phreatic explosion in May 1986 that opened new vents. The site is monitored by seismological agencies as an indicator of the volcano's internal activity. The area is accessible to hikers and serves as a site for vulcanological observation in Central America.
help Tacaná Fumaroles FAQ
Where are the Tacaná fumaroles located?
They are geothermal vents on the slopes of Tacaná, a stratovolcano on the Mexico and Guatemala border. The volcano lies in Chiapas, Mexico, and adjoining Guatemala. [Smithsonian Global Volcanism Program](https://volcano.si.edu/volcano.cfm?vn=341130)
What happened at Tacaná in May 1986?
A phreatic explosion on May 8, 1986 opened a fumarolic vent during a seismic crisis. Gas emission continued from the vent after the explosion. [Smithsonian Global Volcanism Program](https://volcano.si.edu/volcano.cfm?vn=341130)
What do the Tacaná fumaroles emit?
They emit steam and volcanic gases from heated ground on the volcano's slopes. Fumarolic activity indicates heat and gas movement near the volcanic system, but it does not by itself mean that lava is erupting. [Smithsonian Global Volcanism Program](https://volcano.si.edu/volcano.cfm?vn=341130)
Is Tacaná a volcano or a fumarole field?
Tacaná is the volcano, while the fumaroles are individual geothermal vents on its slopes. The volcano is a stratovolcano shared by Mexico and Guatemala, and the May 1986 event created an important new vent. [Smithsonian Global Volcanism Program](https://volcano.si.edu/volcano.cfm?vn=341130)
