Santa María Volcano
Quetzaltenango
Santa María Volcano, located near Quetzaltenango in Guatemala's western highlands, is a prominent active volcano within the Sierra Madre mountain range. Known locally before the Spanish conquest as Gagxanul, meaning "Naked Volcano," it has a complex geological history dating back over 100,000 years. The volcano's most famous event is its colossal 1902 eruption, which was one of the largest eruptions of the 20th century with a Volcanic Explosivity Index of 6. This eruption dramatically reshaped the volcano, creating a deep crater about one kilometer wide and 300 meters deep. The eruption ejected vast amounts of pumice and ash, impacting areas as far as California and causing devastating local effects including darkness lasting over two days and significant loss of life. Santa María remains a notable geological feature, formed by tectonic activity at the subduction zone of the Cocos and Caribbean Plates, and continues to be a significant point of interest for volcanology and tourism.

Histoire
Santa María Volcano's formation began approximately 103,000 years ago through multiple eruptive phases that built its large cone structure.
It was dormant for at least 500 years before its historic eruption in 1902, which was preceded by significant seismic activity earlier that year.
The 1902 eruption was catastrophic, resulting in thousands of deaths and widespread destruction.
Post-eruption, the region experienced social upheaval and land confiscations impacting indigenous communities.
The volcano remains active and is a key feature of Guatemala's volcanic landscape.
