Karisimbi is the highest of the Virunga volcanoes in Central Africa in the border region of Rwanda and DR Congo. It is the 11th highest mountain of Africa and currently in a dormant stage. There are no confirmed historical eruptions.
Its name stems from word "amasimbi" in local Kinyarwanda dialect and means snow. The mountain is believed to be home to spirits and there are many legends associated with it.

Introduction:

Karisimbi, the highest of the Virunga volcanoes, is a complex volcano with a symmetrical sharp-peaked summit. The 2-km-wide Branca caldera, located SE of the 4507-m-high summit, is filled by viscous lava flows and two explosion craters. The large, 1.2-km-wide Muntango pit crater is located south of the summit of the basanitic-to-trachytic volcano. A broad lava plain, formed from lava flows erupted within the caldera and along a chain of parasitic cones, extends SW. More than 100 parasitic cones erupted along a NNE-SSW zone that extends to the shores of Lake Kivu. The youngest Potassium-Argon date obtained is about 10,000 years before present (de Mulder, 1985). The youngest eruptions from Karisimbi produced a group of dome-shaped parasitic vents east of the caldera, which fed viscous lava flows that traveled as far as 12 km to the east, and lava flows from the SW-flank satellitic lava vents.
