THEMIS: The graben of Ceraunius Fossae

Ceraunius Fossae graben (THEMIS_IOTD_20190612)THEMIS Image of the Day, June 12, 2019. This VIS image shows part of Cerunius Fossae. The linear depressions are fault bounded features called graben.

These features form from tectonic forces that are pulling apart the surface, created space for material to “slide down” along the fault. Here the tectonic stress comes from a large, but low, volcanic feature named Alba Mons.
