Santa María volcano, currently Guatemala's most active, is seen here in November 1994. The upper SW flank of the 3772-m-high volcano is cut by a large 1-km-wide explosion crater formed during a catastrophic eruption in 1902. Two decades later the Santiaguito lava dome began growing at the base of the crater, forming the elongated ridge seen below the summit and to the left. Santiaguito has been continually active since 1922, with frequent explosive activity accompanying episodic periods of dome growth and lava extrusion.
