Santa Ana volcano rises beyond the summit crater of Izalco volcano, which formed beginning in 1770 on the northern flank of Santa Ana.  Fumarolic activity producing the faint steam plume in the right foreground continues at Izalco, but has diminished considerably since the cessation of its 200-year-long eruptive period in 1966.  A complex of four nested craters gives the summit of Santa Ana a flat profile.  The slopes of Cerro Verde, a satellitic cone of Santa Ana, are seen at the right.
