Mantle Plume on Mars

Caption

Artist's impression of an active mantle plume – a large blob of warm and buoyant rock – rising from deep inside Mars and pushing up Elysium Planitia, a plain within the planet's northern lowlands. Volcanism at Elysium Planitia originates from the Cerberus Fossae, highlighted in red, a set of young fissures that stretches for more than 800 miles across the Martian surface. Recently, NASA’s InSight lander found that nearly all Martian quakes, or marsquakes, emanate from this one region.
