Scientists take new look at the Tharsis Rise

The Tharsis region on Mars is an enormous volcanic upland located on Mars' equator, at the western end of Valles Marinerus and what a team of geologists now suggest as a large volcanic structure that stretches 4,350 miles (7,000 kilometers) across the red planet. The Olympus Mons, Arsia, Pavonis, and Ascraeus volcanoes are mere cones to one major volcantic struture meaning the gigantic raised plateau, known as Tharsis Rise, is the new volcanic record holder, the study authors say, [National Geographic].

Obvious on the map are the major Tharsis volcanoes: Olympus Mons (18° N, 228° E), Alba Patera (40° N, 250° E) and the volcanic chain consisting of Ascraeus, Pavonis and Arsia montes - now theorized to be cones of the large volcanic structure of the Tharsis Rise.
