Volcán Tacaná, also known as Volcán Tacina in Mexico, the Tacaná Volcano, or simply Tacaná, is an active stratovolcano that is located in the San Marcos Department of Guatemala and in the Cacahoatán and Unión Juárez Municipalities of Chiapas, a Mexican state. It reaches an elevation of 13,320 feet and is part of the Central America Volcanic Arc. It is one of many volcanoes in the Central American Core volcanic chain, which helps support diverse and sensitive ecosystems.
Volcán Tacaná holds a crater that reaches 5.6 miles in length and many smaller calderas and lava domes along its summit. Many of its past eruptions are classified as moderate phreatic eruptions, although it is capable of producing large explosive eruptions like the one that occurred in 70 AD. This volcano can be accessed from Guatemala, on the southern side of the volcano from Finca Navidad, or from many areas in Mexico including Unión Juárez and Talismán Bridge. Visitors can reach the summit of Volcán Tacaná in about ten hours. Although its last known eruption occurred 1986, future eruptions are thought to be possible and could endanger more than 250,000 citizens.
