There are several fine examples of compound martian lava flow fields. This one is just west of the volcano Hecates Tholus, within Elysium Planitia (33°N, 214°W). Several lava flows more than 100 kilometers in length can be found (the direction of flow in this image is from the bottom to the top of the slide). The insert compares these martian flows to the recent activity at Pu’u O’o on the East Rift Zone of Kilauea, Hawaii. Shown in red are the Pu’u O’o lavas erupted between 1983 and 1986, and in blue are the flows erupted from the Kupaianaha lava pond between 1986 and 1991 (slide #19). The distance between the Kupaianaha vent and the coast is approximately 10 kilometers. Mosaic of Viking Orbiter 651A07-14.
