context_page_description: The volcano Tacaná is the second highest peak in Central America at 4,060 metres, located in the Sierra Madre de Chiapas of northern Guatemala and southern Mexico. It is also known in Mexico as Volcán Tacina.
context_section_description: Tacaná is a stratovolcano (composite volcano) that is surrounded by deeply dissected plutonic and metamorphic terrain. It has a 9 km (5.6 mi) wide caldera, with its elongated summit dominated by several lava domes and three large calderas breached to the South.
  Mild phreatic eruptions of Tacaná took place in historical times. Its most powerful known explosive activity, which included pyroclastic flows, occurred at about 70 AD (± 100 years). That large explosion has resulted in Tacaná being classified with a volcanic explosivity index of 4 by the Smithsonian National Museum of Natural History's Global Volcanism Program.
