Shield volcanoes on Venus

Shield volcanoes on Venus

. Approximately 200 small volcanoes, ranging in diameter from 2 thousand to 12 thousand meters, can be identified in this Magellan radar image. They are shield-type volcanoes constructed mainly from eruptions of fluid lava flows similar to those that produce the Hawaiian Islands and sea floor volcanoes on Earth. These small volcanoes are the most abundant geological features on the surface of Venus, believed to number in the hundreds of thousands and perhaps millions. (Courtesy of JPL and NASA.)
