Radar image of Sapas Mons volcano,Venus. The bulk of the volcano is seen as the radar-bright area at the bottom of the frame. This indicates large lava flows. At the top right edge of the volcano is a large circular impact crater. Many of the flows seem to have originated from the flanks of the volcano,rather than the cone. This type of pattern is seen in Hawaiian-type volcanoes on Earth. Sapas Mons is about 400 kilometers across at its base,and rises 1.5 km above the local terrain. It is located within the Atla Regio,a broad equatorial rise at 188 degrees east longitude. The data for this image were gathered by the Magellan radar-mapping spacecraft in 1991 | |
