Fig. 7 Topographic profiles of Ahuna Mons and models.
Topographic profiles of Ahuna Mons and models. (A) Average, half topographic profile of Ahuna Mons (from Fig. 2) shown in diamonds, compared with a calculated profile of a static volcanic dome (blue line). The model profile is calculated with carapace tensile strength of 107 Pa, thickness of 450 m, and ductile material density of 1680 kg m–3. The blue line is dashed where talus material covers the profile. The constant slope of the talus material is highlighted with a black line (35°). (B) Same as (A) but with a calculated profile from a dynamic model of volcanic dome (red line). Key values for the model curve are initial radius of 5.6 km, initial height of 8.2 km, initial actual viscosity of 4 × 1015 Pa s, and a relaxation time of 4 × 102 years. The red line is dashed where talus material covers the profile. O. Ruesch et al. Science 2016;353:aaf4286 Copyright © 2016, American Association for the Advancement of Science
