The Santiaguito lava dome has been continually growing since 1922, seen here in December 1993 from the summit of Santa María. Episodic periods of increased growth have occurred from different vents on the dome complex. The Caliente vent is partially seen at the far left, with La Mitad, El Monje, and El Brujo vents located farther west along the 3-km-long crest of Santiaguito.
