Schenk and Bulmer used their observations of Voyager 1 images, measurements of heights on the digital elevation map generated from the images, and analogies to Earth structures to characterize Euboea Montes. According to them, the mountain is one block of crustal material, due to its polygonal, relatively intact shape. The block was raised and tilted (by about 6°) by thrust faulting. This uplift led to a massive landslide along the mountain's northern flank.
