Earth-Mars Volcano Comparisons: Elevation Color-Mapped Mars
on April 22, 2004
Despite the 2:1 relative size difference between Earth and Mars, the Martian volcano, Olympus Mons, dwarfs Earth's Mauna Loa, Hawaii volcano. When measured from the ocean floor, Mauna Loa is approximately 10km. high compared to Olympus Mons at 23km. This animation is one element of the Earth-Mars comparison. It shows Mars' differing terrain via an elevation color map. Yellow indicates the mean elevation. Green, blue, and purple are low lying areas. Red, brown, and white are the highest elevations. This animation is match-framed to animations #2864 through #2872 and uses the same color map as animation #2866.
