Collapse Features of Olympica Fossae

The depressions in this VIS image likely formed due to both volcanic and tectonic forces. Tectonic forces, like faulting, probably account for the formation of some of the depressions, while collapse into lava tubes and lava flow erosion probably account for the remainder.
