THEMIS: Tectonics meets volcanism in Claritas Fossae

THEMIS Image of the Day, January 10, 2019. This VIS image shows part of Claritas Fossae. The linear features (fossae) are faults. This region of Mars had very active tectonism and volcanism, resulting in the huge volcanos like Arsia Mons … Continue reading

THEMIS: Tectonic scars in Sirenum Fossae

THEMIS Image of the Day, January 4, 2019. The linear features in this VIS image are graben called Sirenum Fossae. Graben are formed when blocks of material move downward between parallel faults. The faults were created by tectonic stresses in … Continue reading

THEMIS: Tectonic chaos in Claritas Fossae

THEMIS Image of the Day, December 27, 2018. Located between the lava plains of Daedalia Planum and Solis Planum, Claritas Fossae is a graben-filled highland. Graben are formed by tectonic activity. In this region of Mars extensive and long lived … Continue reading

THEMIS: Faulting and collapse in Sirenum Fossae

THEMIS Image of the Day, December 19, 2018. The linear depressions in this VIS image are part of Sirenum Fossae. These depressions are called graben, which form by the down drop of material between two parallel faults. The faults are … Continue reading

HiRISE: Layering and faulting in layered deposits in Candor Chasma

Layering and faulting in layered deposits in Candor Chasma. This observation was a last minute one done as nadir-only, meaning when the camera is pointing straight down at the surface, as opposed to an angle when we want to create … Continue reading

THEMIS: Graben in Sirenum Fossae

THEMIS Image of the Day, November 5, 2018. This VIS image shows a section of Sirenum Fossae. The linear features are called graben, and are a sure sign of tension force in the local crust. Graben are formed by blocks … Continue reading

HiRISE: Possible rock falls on steep slopes

Possible rock falls on steep slopes in Cerberus Fossae. Our goal here is to take “before” images at HiRISE resolution in order to identify fresh rockfalls that might be able to be associated with seismic events or Marsquakes detected by … Continue reading

THEMIS: High on the east flank of Pavonis Mons

THEMIS Image of the Day, October 11, 2018. This false-color VIS image shows the eastern flank of Pavonis Mons. The darker streaks are created by wind action, and the curving lines are faults produced when the volcano “relaxed” under the … Continue reading

THEMIS: Fault-edged blocks of Sacra Fossae

THEMIS Image of the Day, August 2, 2018. The right angle intersections in this VIS image are some of the graben that form Sacra Fossae. The fossae are located on the margin of Lunae Planum near the beginning of Kasei … Continue reading
