Active Volcanoes on Venus?

THIS ARTICLE in a newspaper tells of an interpretation of ring structures on Venus, found using radar, as being volcanic in origin. They call them coronae structures - the trench surrounding the peaks. The researchers think the coronae are fields of lava flows and major faults.

They suggest that such structures can only be produced by volcanic activity. And many of them were active in the last few million years.
