Elysium Mons

Today's VIS image shows a cross section of Elysium Mons, including part of the summit caldera. Unlike the Tharsis volcanoes to east, there are very few identifiable lava flows on the flanks of the Elysium Mons. In profile the volcano looks like Mt. Fuji in Japan. Mt. Fuji is a stratovolcano. A stratovolcano, also known as a composite volcano, is a conical volcano built up by multiple layers of lava and ash erupting solely from the summit caldera. The Tharsis volcanoes are shield volcanoes, which will host flank eruptions, but rarely ash eruptions. Elysium Mons is 12.6km (7.8 miles) tall. For comparison, Mt. Fuji is 3.7 km (2.3 miles) tall.
