HiRISE: Ridge in Hesperia Planum
A ridge in Hesperia Planum. Our objective is to look for fault offsets to see if these thrusts are surface breaking or not. Hesperia Planum is a broad lava plain in the southern highlands of Mars. The plain is notable … Continue reading

THEMIS: Labeatis Fossae in Tempe Terra
THEMIS Image of the Day, July 4, 2019. The linear depressions in this VIS image are graben called Labeatis Fossae. Graben are formed when extension between paired faults causes the material to move downward. These are part of a general … Continue reading

THEMIS: Arsia Mons faults, graben, and pit craters
THEMIS Image of the Day, July 1, 2019. Today’s VIS image is located on the lower flank of Arsia Mons. The linear features are tectonic faults. The lava flows originating from Arsia Mons are among the youngest on the surface … Continue reading

Do ice-squeezed aquifers cause marsquakes?
As the Mars InSight lander begins listening to the interior of Mars, some scientists are already proposing that some marsquakes could be signals of groundwater beneath the frozen surface of the Red Planet. The idea, proposed by Michael Manga, a … Continue reading

THEMIS: Crazy craters
THEMIS Image of the Day, June 19, 2019. Today’s VIS image shows two craters located on the margin of Syrtis Major Planum. The two large craters are not circular. The flatter sides are caused by the pressure wave generated by … Continue reading

HiRISE: Nilosyrtis Mensae
Let us now contemplate Nilosyrtis Mensae. There is a fault attached to a trough here; both have the same orientation. This image helps us to understand stress fields on Mars. Beautiful Mars series. [More at links]

HiRISE: The fault in our Mars
This image of northern Meridiani Planum shows faults that have disrupted layered deposits. Some of the faults produced a clean break along the layers, displacing and offsetting individual beds (yellow arrow). Interestingly, the layers continue across the fault and appear … Continue reading
