A vigorous steam plume, seen here from the east in September 1996, rises above Pico Central, the glacier-clad summit of Huila volcano. The 5364-m-high volcano is Colombia's highest active volcano. Long-term, persistent steam plumes occurred at Huila prior to the onset of eruptive activity in 2007. Before then, only a single 16th century eruption was known during historical time.
