The view is centered around the area called the Ares Vallis (below right, the water filled basin). This area shows variety of water related features, e.g. sediments, river canyons, and flat-bottomed crater (characteristic of an ancient water-filled craters). Some water overflowed from the crater that contains them, creating flood across the plain.
Also shown are some meteors impacting the Martian surface.
I am not very sure what is that volcano on the left. Volcanism is important in forming water in Mars. Volcano produces material for a thicker atmosphere, in this visualization, you can even see there’s a plume of gas coming out from the volcano. This process makes the planet warmer and makes it possible for water to form. That volcano is probably part of the Alba Mons volcanic system, although I think Alba Mons should be a little bit to the north.
The color of Mars is not red during that time, because the oxidation of the soil happens when the volcanism stops.
