The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Tacaná volcano on the Mexican-Guatemalan border is a symmetrical stratovolcano rising 1800 m above its base and forms the NW end of the Central American Volcanic Belt.
Tacana consists of overlapping volcanic edifices, reflecting a migration of vents from the NE to the SW over time. The youngest vent is the San Antonio lava dome in a crater on the upper SW flank, which was the site of most recent activity.
Historic eruptions of Tacaná were small phreatic explosions in 1855, 1878, 1949–1950 and 1986, from both Tacaná and San Antonio. The eruption in 1950 was the largest and produced pyroclastic flows.
Active fumaroles are found at 3600 m altitude and hot springs in various locations at the base of the volcano.
A number of shallow earthquakes has occurred recently under the volcano. The largest was a magnitude 4.0 event at 5 km depth under the eastern flank. No reports of unusual activity at the volcano are available.
Batu Tara photos: A remote island in the Flores Sea of Indonesia formed by a single volcano that has been in strong strombolian eruption for years. We regularly lead expeditions to there where we camp several days to observe it.
