Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Fort Portal
These grass-covered tuff cones are among the many of the Fort Portal volcanic field in Uganda. The carbonatite lavas and tuffs were erupted from about 50 cones and maars, some of which now contain crater lakes. Photo by Nelson Eby (University of Massachusetts).

The carbonatite lavas and tuffs of the Fort Portal volcanic field in Uganda, NE of Mount Ruwenzori between Lake Albert and Lake Edward, consists of a group of tuff cones and maars covering an area of about 145 km2. About 50 volcanic vents, some of which now contain crater lakes, were erupted through Precambrian gneiss in an WSW-ENE-trending area north of the town of Fort Portal. Several additional vents are located in the Kasekere (Rusekere) area to the NE. Radiocarbon dates of about 4,700-4,000 years ago were obtained from ash deposits in the volcanic field. Holmes (1950) noted that Kasensankaranga Crater in the Fort Portal area means "spewer of roasted material," implying observed activity.
