0–20 s: comparison with images of different terrestrial and extraterrestrial impact craters. 21–24 s: location of the Silverpit Crater. 25–38 s: top and base Cretaceous Chalk surfaces. The view is from the southeast. 39–56 s: central uplift in the center of the Silverpit Crater, view from southeast. 57–60 s: east–west seismic line showing extensional faults on the western rim of the crater. 60–84 s: top Cretaceous Chalk surface showing extensional fault blocks on the western rim. View from south, below and above this surface. 85–93 s: top Cretaceous Chalk surface with flight over central high from west rim to east rim of the crater. 94 s–108 s: top Cretaceous Chalk Surface showing compressional faults on the eastern rim. Comparison with the expression of faults on east–west seismic line. 109–123 s: east–west seismic line showing central high. Animation through the seismic volume. 124–143 s: top Cretaceous Chalk surface: view of the crater and central high from above. 144–153 s: top Cretaceous Chalk surface: view of the crater and central high from above. Example of the multiple ring features. 154–157 s: image of Tyre Crater on Europa. 158–162 s: summary of key points. 163–168 s: summary of seismic data owners.
