Perspective view of pancake domes in Alpha Regio,Venus

3-D computer generated perspective view of pancake volcanoes on the eastern edge of Alpha Regio, Venus. This image was created by superimposing Magellan radar images on Venus topography, and colored based on images from the Venera 13 and 14 landers. The viewpoint is at 30S,11.8E at an elevation of 2.4 km. The circular features are "pancake" dome volcanoes, about 25 km in diameter and 750 m high, formed by extrusion of highly viscous lava onto the surface. The vertical exaggeration is 23 times.
