About Santiaguito
Santiaguito is a cluster of lava domes on the western flank of the Santa María volcano in Quetzaltenango Department, Guatemala, and is one of the country’s most active volcanic complexes. It formed as a direct consequence of the catastrophic 1902 Santa María eruption.
Following the 1902 eruption of Santa María, lava-dome growth at Santiaguito began in the decades that followed and continued through the 20th and 21st centuries, creating multiple overlapping domes through repeated extrusion and collapse.
Santiaguito sits on the western flank of Santa María in western Guatemala’s highlands, within Quetzaltenango Department, accessible from local towns and routes used by visitors and volcanological teams.
- Ongoing activity: Dome growth began in the early 20th century after the large 1902 eruption of nearby Santa María; the complex has produced frequent ash plumes and pyroclastic flows since then.
What to See#
- Caliente dome: The active vent known as Caliente is the most frequently active dome within the complex and produces regular Vulcanian-style explosions and lava extrusion.
