Magellan Probe: radio image of Landslides in Navka Region

Caption NASA originale:"The Magellan spacecraft has observed remnant landslide deposits apparently resulting from the collapse of volcanic structures. This Magellan radar image is centered about 25,4° south latitude and 308° east longitude in the southwestern Navka Region of Venus. The image shows a 17,4 Km (approx. 10,8 mile) diameter volcanic dome on the plains. The dome is approximately 1,86 Km (approx. 1,2 mile) in height and it has a slope of about 23°. The northwest and northeast flanks of the dome have collapsed to form landslides that have deposited debris on the plains. The image shows an area 110 Km (approx. 68 miles) across and 100 Km (approx. 62 miles) in length".
