About this image

Today's image shows the eastern flank of Ascraeus Mons. Several tectonic fractures and collapse features, as well as lava flows, are visible in the image. The collapse features vary in shape from circular to linear outlines. The majority of the collapse features don’t interact with the surface lava flows, indicating that the collapse features were formed after the main emplacement of lava flows from the summit and near summit vents. Ascraeus Mons is the northernmost of the three aligned Tharsis volcanoes and is the tallest at 18 km (11 miles), for comparison Mauna Kea - the tallest volcano on Earth - is 10 km tall (6.2 miles, measured from the base below sea level).
