A powerful explosion on April 20 sent ash and toxic gases into the atmosphere and ejected large boulders that narrowly missed illegal hikers.
Location and Origin
- Location: Located in western Guatemala near the city of Quetzaltenango (Xela).
- Formation: It formed in the wake of the catastrophic 1902 eruption of the Santa María Volcano, which was one of the largest eruptions of the 20th century.
- Nature: It is not a single cone but a lava dome complex growing within the 1.5-km-wide crater scar left by Santa María.
- Dome Complex: Consists of four distinct domes: Caliente (currently active), La Mitad, El Monje, and El Brujo.
- Elevation: Reaches approximately 2,523 metres (8,277 feet).
- Active Vent: All current activity is concentrated at the Caliente vent, which has been continuously erupting since 1922.
Scientific Monitoring
- Agencies: Monitored primarily by INSIVUMEH (Guatemala's national institute for volcanology) and the Global Volcanism Program of the Smithsonian Institution.
- Alert Status: Currently maintained at Orange Alert (High Instability).
Safety Warning for Travelers
- Restricted Access: Climbing the actual Santiaguito dome is strictly prohibited and considered a "death wish" by local authorities.
- Safe Viewing: The recommended way to see the activity is from the Santiaguito Mirador (lookout) on the flank of the adjacent Santa María volcano.
- Lahar Risk: Visitors must stay away from riverbeds south of the volcano during rain, as mudflows can be hot and destructive.
