Transient hot spots on Venus: Best evidence yet for active volcanism

Posted by Emily Lakdawalla on 2015/06/18 06:42 CDT | 3 comments

In a paper released in Geophysical Research Letters today, Eugene Shalygin and coauthors have announced the best evidence yet for current, active volcanism on Venus. The evidence comes from the Venus Monitoring Camera, which saw transient hot spots in four locations along a system of rifts near Venus' equator. They saw the hot spots in two distinct episodes in 2008 and 2009.
