The Santiaguito Volcano was created in the wake of the Santa María Volcano’s 1902 eruption. This eruption destroyed Santa María’s former summit and left some 5,000 people dead. It was one the largest eruptions of the 20th century. The massive Santiaguito dome-complex has been growing ever since and is accompanied by continuous explosions every 20 minutes, adventurous travelers hike up Santiaguito itself, some guiding companies will get you within a quarter mile of the crater.
