The Dali and Diana Chasma system consist of deep troughs that extend for 7400 kilometers (4600 mi) and are very distinct features on Venus. Those chasma connect the Ovda Regio and Thetis Regio highlands with the large volcanoes at Atla Regio and thus are considered to be the Scorpion Tail of Aphrodite Terra. The broad curving scarp resembles some of Earth’s subduction zones where crustal plates are pushed over each other.
