An ash column rises above Santiaguito lava dome in March 1988.  Explosive eruptions such as these are typical of activity that has occurred at the growing lava dome since 1922.  The Santiaguito dome was constructed at the base of a large crater, seen here in profile from the Pacific coastal plain to the SE.  The crater cuts the SW flank nearly to the summit of conical Santa María volcano. Photo by Lee Siebert, 1988 (Smithsonian Institution).
