Gula Mons

Towering 4 km (3 mi) above the surface in NW Eistla Regio is the shield volcano Gula Mons. This type of volcano is similar to those found on the Hawaiian Islands; possibly resulting from hot material rising from the interior and heating the crust. Shield volcanoes form when hot, fluid lava erupts non- explosively. The radar-bright area in Eistla Regio consists of both the summit and radial troughs and scarps extending to the northeast down the slope of Gula Mons. Regional expansion of the crust is obvious in this area because of the presence of graben.
