It is shown that these strain ellipses indicate more strain than could be due to the bulge building alone.
About 10 percent of the Tharsis surface bulge exhibits elliptical impact craters, which are the largest strain markers in the solar system.
The amount of horizontal strain on the Martian Tharsis bulge is quantified in order to provide further information on the tectonic evolution of this province. Quantitative analysis of the extensional tectonics of Tharsis bulge, Mars - Geodynamic implications
