Santiaguito
Guatemala
Level 4
Santiaguito is the name of the dome complex that grew inside the collapse scar left by the catastrophic eruption and partial collapse of Santa María stratovolcano in 1902. Its currently active dome is called Caliente (the "hot one"). Symmetrical, forest-covered Santa María volcano is one of the most prominent of a chain of large volcanoes that rises dramatically above the Pacific coastal plain of Guatemala. Santa Maria erupted catastrophically in 1902 destroying its former summit. Santa Maria is a popular excursion destination and the summit offers spectacular views onto erupting Santiaguito.
