Shasta, California

Much like Kilimanjaro (the tallest mountain in Africa), Shasta is a monster of a volcano. Unlike Kilimanjaro, Shasta is an subduction-related volcano rather than a rift volcano, but they are very similar otherwise. Shasta has a prominent parasitic cone - Shastina - that has grown on the side of the larger edifice - and even a satellite cone to the west in Black Butte (north is to the bottom of the NASA Earth Observatory image). Both of these cones erupted during the Holocene (last 10,000 years). However, the last significant eruption at Shasta was only 216 years ago, when the volcano produced a VEI 3 eruption with pyroclastic flows and lahars speading in the valley surrounding the volcano.
