The symmetrical Visoke volcano is the NE-most of a cluster of large stratovolcanoes at the southern end of the Virunga Range on the border of the Democratic Republic of Congo and Rwanda. The 3711-m-high stratovolcano contains a 450-m-wide lake in its summit crater. A NE-SW-trending fissure zone has produced many cinder cones NE of the trachyandesitic volcano. An eruption in 1957 formed two small cones on the north flank, 11 km from the summit.

The symmetrical Visoke volcano is the NE-most of a cluster of large stratovolcanoes at the southern end of the Virunga Range. The 3711-m-high stratovolcano contains a 450-m-wide lake in its summit crater (left center). Lobate lava flows descend the flanks of the volcano. A NE-SW-trending fissure zone has produced many cinder cones NE of the volcano (top). An eruption in 1957 formed two small cones on the north flank, 11 km from the summit.
