This image is a composite of 30 orbits recorded by the Magellan spacecraft in April 1991 superimposed on Pioneer Venus topography (the small gray triangular wedge in the upper right hand corner of the image). This image, with a resolution of 120 meters (370 feet), centered on the equator at 288 degrees east longitude and shows the complex deformation associated with faulting in Devana Chasma. These faults have a relatively uniform spacing of approximately 5 kilometers (3 miles) and are part of 100 to 180 kilometer (60 to 108 miles) wide zone of deformation. A group of bright (rough) lava flows 70 kilometers by 280 kilometers (42 by 168 miles) flow down the raised west flanks of the Devana Chasma rift valley. The new Magellan data reveal remarkable detail and complexity in this deformed terrain. Analysis of images from areas such as Devana Chasma is expected to improve our understanding of the global tectonic forces affecting Venus.
