Atla Regio

Atla Regio

Fig. 7.19 . Fractures, seen as bright, thin lines, criss-cross the volcanic deposits in part of the Atla region of Venus. The fractures are not buried by the lava, indicating that the convulsive tectonic activity post-dates most of the volcanic activity. This Magellan radar image is approximately 350 kilometers across, and centered at 9 degrees south latitude and 199 degrees east longitude. Several circular volcanoes, surrounded by radar-bright lobes, are also present. This region is named Atla after a Norse giantess, mother of Heimdall. (Courtesy of NASA/JPL.)
