Distant view of Akan, a group of stratovolcanoes, that lies within a shallow depression. Me-Akan, the active vent, is the steaming volcano on the left. Some volcanologists think the shallow depression is a caldera. Photograph courtesy of and copyrighted by Paul J. Buklarewicz.

Me-Akan is a stratovolcano in the depression and the only active vent. Me-Akan has erupted at least 15 times since about 1800. Eruptions prior to 1955 were weak. The 1955 eruption was phreatic and explosive. The most recent eruption was in 1988. Although it was phreatic, like most eruptions at Me-Akan, it lasted just over a month. Most eruptions at Me-Akan last less than one day. This photo shows a small lake and steaming vents. Photograph courtesy of and copyrighted by Paul J. Buklarewicz.
