Ganis chasmata, Venus: Site of active volcanism?
In 2008 and 2009, Venus Express saw transient hot spots in this region of Venus, a site near the equator called Ganis Chasma. There are enormous volcanoes in this area (Ozza Mons at lower right and Maat Mons at lower left) but the hot spots were along the fissures that cross the image from upper left to lower right. The whole region visible here is about 2000 kilometers square. This image is made from data from the Magellan mission, which ended in 1994.

Here's an annotated version of the map.
