THEMIS: Fractures on Pavonis Mons’ flank
THEMIS Image of the Day, October 31, 2017. This image shows part of the western flank of Pavonis Mons. The linear features are faults. Faulting usually includes change of elevation, where blocks of material slide down the fault. Paired faults … Continue reading

THEMIS: Pit craters on Ascraeus Mons
THEMIS Image of the Day, September 4, 2017. This image shows a collapse feature on the southeastern flank of the volcano. The circular/scalloped margin of the collapse is typical for ceiling collapse into a lava tube. However, the potential lava … Continue reading

THEMIS: Tectonics in Sirenum Fossae
THEMIS Image of the Day, May 3, 2017. Today’s false color image shows part of Sirenum Fossae. The linear depressions in this image, called graben, were formed by tectonic activity. The THEMIS VIS camera contains 5 filters. The data from … Continue reading

THEMIS: Varieties of geo-chaos in Gorgonum
THEMIS Image of the Day, May 2, 2017. Today’s false color image shows part of Gorgonum Chaos. Chaotic regions form when groundwater escapes to the surface, undermining it and causing the ground to collapse. The linear depression at the bottom … Continue reading

THEMIS: Tempe Fossae graben in false color
THEMIS Image of the Day, April 14, 2017. Today’s false color image shows a section of Tempe Fossae located in Tempe Terra. This is a graben that formed when subsurface forces pulled the ground apart, and a portion of the … Continue reading

THEMIS: Faulting & graben in Claritas Fossae
THEMIS Image of the Day, January 13, 2017. Today’s VIS image shows graben called Claritas Fossae. These are caused when the ground is pulled apart, and the land between parallel faults drops down. More THEMIS Images of the Day by … Continue reading

THEMIS: Tectonics in Sirenum Fossae
THEMIS Image of the Day, January 12, 2017. The linear depressions in this VIS image are graben. Graben are formed from tectonic activity with large blocks of material moving downward between paired faults. The crater in the bottom half of … Continue reading

THEMIS: ‘Channels’ in Icaria Fossae
THEMIS Image of the Day, December 8, 2016. The channel-like features in this VIS image are tectonic graben. The graben (called Icaria Fossae) are located in Terra Sirenum. The graben are caused by tectonic forces that faulted the bedrock, allowing … Continue reading
