Not only volcanic features

A very interesting feature lies just about 30 km east of the volcano flank. Here a second, less developed volcano rises (well visible in the color-coded image). Presumably less viscous flows erupted here from a so-called fissure vent, a structure also known from Iceland or Hawaii on Earth.

But not only volcanic features are present within this image mosaic. The large 30 km wide impact crater 60 km north of Jovis shows a so-called fluidized ejecta layer and a fractured crater floor. This means, that the impactor must have hit a water- or ice saturated ground to form this distinctive ejecta layer.
