• Venusian Volcanic Features

Scientists nicknamed this type of volcano a tick. About 65.6 kilometers (41 miles) across at the base, this volcano has a flat, concave summit 34.8 kilometers (22 miles) in diameter. The sides of the volcano are characterized by radiating ridges and valleys. The rim of the volcano to the west appears to have been breached by dark lava flows that emanated from a shallow summit pit 5.4 kilometers (3.4 miles) in diameter and traveled west along a channel. A series of coalescing, collapsed pits 2 to 10 kilometers (1.2 to 6.2 miles) in diameter is 10 kilometers (6.2 miles) west of the summit rim. The black square represents missing data.
