Perspective view of fractures in Sirenum Fossae in the southern hemisphere of Mars. The view shows the movement of the crust, likely in response to the tectonic stresses linked to volcanic activity of the wider region. In this kind of scenario, fractures divide the crust into blocks: movement along a pair of faults causes the centre section to drop down into ‘graben’.
The scene is part of the region imaged on 5 March 2017 during Mars Express orbit 16688. The ground resolution is about 14 m/pixel and the images are centred at 28°S / 215°E. North is to the right.
