Have there been any major fatalities associated with the eruption of the Santa Maria volcano in the past?
One under-studied example is the 1902 Plinian eruption of Santa María volcano, Guatemala. Sources from the time tell us that volcanic ash from the eruption travelled thousands of kilometres and that associated hazards may have caused several thousand fatalities.

What was the name of the volcano that erupted 1902?
The eruption of Santa Maria volcano in 1902 was one of the largest eruptions of the 20th century, forming a large crater on the mountain’s southwest flank. Since 1922, a lava-dome complex, Santiaguito, has been forming in the 1902 crater.
What happened in the 1902 eruption of Santa Maria?
The eruption of Santa Maria volcano in 1902 was one of the largest eruptions of the 20th century, forming a large crater on the mountain’s southwest flank. Since 1922, a lava-dome complex, Santiaguito, has been forming in the 1902 crater. Growth of the dome has produced pyroclastic flows as recently as the 2001—they can be identified in this image.
