Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Santa Maria
Santa María volcano, the most active in Guatemala, has a sharp-topped, conical profile that is cut on the SW flank by a large, 1-km-wide crater formed during a catastrophic eruption in 1902. The large dacitic Santiaguito lava-dome complex (center) has been growing at the base of the 1902 crater since 1922. Lava flows can be seen extending down the flank of the compound lava dome, whose growth is accompanied by a frequent minor explosions, along with periodic lava extrusion, larger explosions, pyroclastic flows, and lahars.
