What characteristic visible in space imagery accounts for the structure's slightly elongated shape?
Answer
Tectonic stresses acting on the structure after the initial impact
Images often highlight the elliptical shape of the visible dome, which has an axial ratio of about 1.5 to 1, attributed to tectonic stresses acting on the structure after the initial impact.
